<blockquote>Vítejte zpět u tématu ochrany GC kolony! Pokud jste zmeškali <a target="_blank" rel="noopener noreferrer" href="https://gcms.cz/article/6767">první část</a> nebo si chcete své znalosti osvěžit, další tipy k ochraně GC kolony najdete <a target="_blank" rel="noopener noreferrer" href="https://gcms.cz/article/6767">zde</a>.</blockquote>Ochrana GC kolony a jednotlivých komponent přístroje před znečištěnými vzorky nebo kontaminanty je zásadní. Netěkavé nebo vysokomolekulární složky mohou kontaminovat stacionární fázi, což vede ke zhoršení rozlišení píků, nižší přesnosti analýzy a zkrácení životnosti kolony. Odříznutí poškozené části kapilární kolony často dočasně obnoví její účinnost, postupem času však dochází k degradaci, která znemožní další použití kolony. Pokud pozorujete rychlý pokles účinnosti separace, existuje několik jednoduchých způsobů, jak kolonu lépe chránit a prodloužit její životnost.<h3>Používejte liner se skelnou vatou</h3>Liner je první obrannou linií kolony a jeho volba má zásadní vliv na množství kontaminantů, které se mohou dostat do kolony. Nejjednodušším řešením je použití lineru s malým množstvím silanizované skelné vaty, která zachycuje netěkavé složky a zabraňuje jejich přímému vstupu do kolony.<blockquote>Upozornění: Skelná vata může zvyšovat aktivitu vůči kyselinám, zásadám a pesticidům. Drcení skelné vaty může odhalit nedeaktivované sklo a volné silanolové skupiny (–OH), a to i v případě, že byla vata původně deaktivována. To vede ke zvýšené aktivitě a horší reprodukovatelnosti, proto se důrazně doporučuje používat předplněné linery, nikoli linery plněné svépomocí.</blockquote>Kromě volby lineru se skelnou vatou dbejte také na to, aby byl liner (stejně jako ostatní spotřební materiál) bez nahromaděných nečistot, které se mohou v průběhu času vytvářet. Zbytky ze sept, jádra sept a další částice se mohou zachytit ve skelné vatě a často nejsou na první pohled patrné. Pravidelná výměna lineru (a dalšího spotřebního materiálu dle potřeby) pomáhá omezit potřebu řešení problémů a zjednodušuje údržbu systému.<h3>Vypalujte kolonu (bake-out)</h3>Nejjednodušším způsobem, jak snížit kontaminaci kolony, je zařadit krátký vysokoteplotní „bake-out“ (vypalování) na konec standardní GC metody. Tento krok pomáhá odstranit vysokovroucí kontaminanty, které by jinak v koloně zůstávaly a způsobovaly její poškození.Při vypalování musí být konečná teplota pece nastavena dostatečně vysoko, aby došlo k eluování těchto složek, ale zároveň nesmí být překročena teplota, při které by došlo k tepelnému poškození kolony. Vypalování lze provádět buď izotermicky, nebo – častěji – postupným zvyšováním teploty pece až do eluce posledních složek z kolony.<blockquote>Upozornění: Nikdy nepřekračujte maximální povolenou provozní teplotu kolony. Při izotermickém provozu nepřekračujte horní teplotní limit kolony po dobu delší než 15 minut.</blockquote>

Zveme Vás na sérii krátkých, ale praktických online seminářů, které jsme připravili pro všechny, kdo pracují s chromatografií a laboratorní analýzou. Každý z webinářů je zameřený na jedno konkrétní analytické téma a nabídne jasné tipy, rešení nejčastejších problémů i doporučení.Již 13. 2. 2026 od 10:00 hodin se mužete tešit na téma: Sample Prep and Analysis for Fat-soluble Vitamins.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Altium_priprava_vzorku_pro_analyzu_vitaminu_rozpustnych_v_tucich_1b280b7ea1.jpg" alt="Altium - Agilent: Příprava vzorků pro analýzu vitamínů rozpustných v tucích – tipy a aplikace" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Altium_priprava_vzorku_pro_analyzu_vitaminu_rozpustnych_v_tucich_1b280b7ea1.jpg 245w," sizes="100vw" width="842" height="286"><blockquote><a target="_blank" rel="noopener noreferrer" href="https://events.teams.microsoft.com/event/494d4b0d-da70-4504-9720-1bc7f82524fe@31139e4d-0687-4dc9-ada3-e46652ffbd94/registration">Registrujte se na webinář pomocí tohoto odkazu</a></blockquote>Vitamíny rozpustné v tucích jsou přirozenou součástí lipidové frakce potravin, kde se vyskytují společně s triglyceridy, steroly, fosfolipidy a dalšími lipidy. Tato „těsná spolupráce“ s ostatními tukovými složkami sice dává biochemický smysl, ale z analytického hlediska výrazně komplikuje jejich izolaci a přesné stanovení.Tradiční postupy přípravy vzorků jsou často časově náročné, pracné a náchylné k chybám, což se negativně promítá do reprodukovatelnosti i výtěžnosti analýzy. Řešení pro přípravu vzorků od společnosti Agilent Technologies tento problém mění v konkurenční výhodu: zjednodušují a urychlují celý pracovní postup, zajišťují konzistentní a reprodukovatelné výsledky a maximalizují výtěžnost analytů i v těch nejkomplexnějších matricích potravin a doplňků stravy.Výsledkem je spolehlivější analytika, vyšší efektivita laboratoře a jistota dat, na která se lze skutečně spolehnout.Webinář bude probíhat v anglickém jazyce.<blockquote>Přednášející: EMEAI IDO (Product Specialist Chemistries and Supplies, Agilent Technologies)Giorgio got his Master Degree in Chemistry at the University of Trieste, Italy.He has more than 20 years of experience in Chromatography Columns troubleshooting, sales and business development.He covered various international positions and at present is Agilent Product Specialist EMEAI-IDO, and responsible for developing the Agilent Chemistries and Supplies business in the indirect sales channels of Central Eastern Europe, Africa and the Middle East.</blockquote>

Ačkoliv moderní zemědělství potřebuje vycházet z přesných dat o půdních, rostlinných i environmentálních podmínkách v reálném čase, cenově dostupná, dostatečně citlivá a zároveň robustní monitorovací zařízení pro tento účel v současné době chybí. Jako vhodné řešení se podle vědců nabízí nízkonákladové senzory založené na nových chytrých materiálech a technologiích tisku. Dosavadní výsledky multiioborového výzkumu i návrhy na vývoj těchto zařízení představili výzkumníci z Česka, Velké Británie, Španělska i USA v přehledovém článku v prestižním časopise <a target="_blank" rel="noopener noreferrer" href="https://www.nature.com/articles/s41467-026-68778-6#Abs1">Nature Communications</a>.„Senzorické technologie pro monitorování zdraví rostlin jsou stále v plenkách. Na trhu jsou běžné dostupné jen jednoduché senzory, které jsou schopné monitorovat pouze základní parametry jako například pH, vlhkost v půdě, případně teplotu. Pokud však mají zemědělci čelit současným výzvám včetně klimatických změn a zajistit pro lidstvo dostatek potravy, potřebují mnohem účinnější pomocníky, jež jim umožní monitorovat například i různé patogeny včetně bakterií či plísní. Podle nás je vhodným řešením kombinace nových chytrých materiálů a tisku pro produkci levných, odolných a škálovatelných materiálů,“ uvedl první autor článku David Panáček z CATRIN, který na studii pracoval během své stáže v Imperial College London.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CATRIN_Soucasne_senzory_nestaci_Vedci_navrhuji_novou_cestu_ke_sledovani_zdravi_rostlin_b4014952a3.jpg" alt="CATRIN: David Panáček" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CATRIN_Soucasne_senzory_nestaci_Vedci_navrhuji_novou_cestu_ke_sledovani_zdravi_rostlin_b4014952a3.jpg 208w," sizes="100vw" width="1536" height="1152">Senzory pro monitorování zdraví rostlin například v porovnání s podobnými zařízeními pro humánní medicínu pokulhávají. Klíčovou roli v možném posunu hraje podle autorů pokrok v materiálových vědách, jenž vývoj škálovatelných senzorových technologií umožní. „Tiskové techniky včetně inkoustového tisku, sítotisku, aerosolového tisku, 3D tisku a přímého laserového zápisu nabízejí flexibilní cesty k výrobě ohebných senzorů, senzorů pro velké plochy i senzorů integrovaných přímo do rostlin. Přehledový článek shrnuje nedávný pokrok v oblasti tisknutelných nízkorozměrných materiálů pro zemědělské senzory, analyzuje jejich fyzikálně-chemické vlastnosti ve vztahu k senzorovému výkonu a diskutuje hlavní výzvy a budoucí příležitosti vyžadující mezioborovou integraci,“ uvedl jeden z korespondujících autorů Michal Otyepka.Výzkum propojil materiálové vědce, chemiky, biology, odborníky na senzing i technologie tisku. Materiálový výzkum a využití chytrých materiálů na bázi grafenu zaštítili vědci CATRIN Univerzity Palackého a VŠB-Technické univerzity Ostrava, znalostmi o vývoji rostlin, jejich reakcích na stresové podmínky i monitorování jejich vlastností přispěli rostlinní biologové z CATRIN, o oblast elektroniky se postarali výzkumníci z Imperial College London, technologiím tisku se věnovali zástupci <a target="_blank" rel="noopener noreferrer" href="https://lcms.cz/companies/36">CEITEC – VUT</a>. V týmu nechyběli ani přední odborníci na senzing z Katalánského institutu nanověd a nanotechnologií v Barceloně a svými bohatými znalostmi přispěl i „otec senzingu a elektrochemie“ Joseph Wang z University of California San Diego.„Jedná se o průlomovou studii na toto téma, k níž se podařilo přizvat skutečně velká jména v daných oborech. V neposlední řadě studie dokládá to, že interdisciplinarita v CATRIN dává vzniknout zcela novým a perspektivním výzkumným tématům, jako je rostlinný senzing a jeho využití pro studium interakce rostlin s prostředím a chytrém zemědělství,“ doplnila další z korespondenčních autorů Nuria De Diego. &nbsp;

LECO: State of the Art Technology for Aroma, Flavour and Fragrance Analysis

State of the Art Technology for Aroma, Flavour and Fragrance Analysis

Explore the capabilities of LECO technology and the impact it is having on overcoming the challenges faced in the Aroma, Flavor, and Fragrance industry.

Technology for Aroma, Flavour and Fragrance Analysis

As our understanding of the human impact on the environment deepens, so too does the conversation and action surrounding two linked topics: how companies can adopt more sustainable operations and which other compounds necessitate monitoring to address the latest safety and environmental concerns.
When trying to assess sustainability in a GC-based lab, organic solvents, liquid cryogen and helium are often at the top of lab managers&#39; lists to reduce. Hydrogen carrier gas, solvent-free, and cryogen-free sample introduction methods offer a solution to these problems. However, are they compatible with the expanding number of species and lower detection limits now required for many organic compound monitoring lists?
In this webinar, Hannah Calder, Environmental Air – Market Development Manager at Markes International, and Dr. Aaron Davies, Commercial Marketing Manager – Thermal Desorption at Markes International, will discuss case studies where air monitoring lists are growing in complexity, such as in ozone precursor monitoring, air toxics, and organic ozone-depleting substances. In each case study, as well as looking at how the methodology can meet the requirements of monitoring, they will also discuss how the method can be made more sustainable, ensuring longevity and accountability.
By attending this webinar, you will learn:
<ul>
<li>About proposed changes to monitoring of ozone precursors in Europe, air toxics in the USA and ozone depleting substances in China
</li>
<li>How sustainability can be introduced into laboratories analysing organic compounds, with a focus on air monitoring
</li>
<li>What the challenges are when adopting a more sustainable approach, and tools available to help facilitate the conversion process
</li>
</ul>
Who should attend?
<ul>
<li>Researchers interested in monitoring of organic compounds
</li>
<li>Laboratory and project managers specialising in air samples
</li>
<li>Environmental consultants

SelectScience: Balancing lab sustainability and expanding VOC monitoring requirements for air analysis

Balancing lab sustainability and expanding VOC monitoring requirements for air analysis

Case studies where air monitoring lists are growing in complexity, such as in ozone precursor monitoring, air toxics, and organic ozone-depleting substances.

VOC monitoring requirements for air analysis

Learn how GC-based techniques widely used in VOC monitoring can be easily applied to PFAS analysis.
Exposure to per- and polyfluoroalkyl substances (PFAS) can occur through a number of pathways. One of the less understood, but equally important, routes is air. The movement of PFAS through air can happen relatively unimpeded when compared to water and soil, and deposition from the air is another way that they can become contaminated.
Sources of PFAS in the air can be industrial activity, disposal of PFAS containing materials or simply emissions from PFAS containing products. Monitoring of these different environments and matrices is commonly carried out using GC based techniques for other VOCs, so how does monitoring of PFAS differ? Join this webinar to hear about how techniques already broadly used for VOC monitoring can be successfully applied to PFAS measurements from air and materials.
By attending this webinar, you will learn:
<ul>
<li>Which PFAS are GC amenable and which make most sense to monitor with other techniques
</li>
<li>How current VOC monitoring standards can be applied to PFAS monitoring in air
</li>
<li>What changes to those methods mean in terms of performance and new challenges they introduce
</li>
<li>What detection limits are possible in air and what is needed for different environments and matrices
</li>
</ul>
