<p><strong>Dimethylkarbonát (DMC) hraje klíčovou roli v elektrolytech lithium-iontových baterií, kde čistota rozpouštědla přímo ovlivňuje výkon, bezpečnost i životnost baterie. I stopová množství nečistot mohou přispívat k degradaci mezifázové vrstvy pevného elektrolytu (SEI), spotřebě lithiových iontů nebo tvorbě plynů – tedy jevům, které snižují účinnost i bezpečnost baterií.</strong></p><p>S pokračujícím vývojem bateriových materiálů musí analytické přístupy poskytovat jak vysokou citlivost, tak identifikaci s vysokou mírou spolehlivosti. Nedávná aplikační studie společnosti LECO ukazuje, jak kombinace dvou platforem GC-MS umožňuje komplexnější charakterizaci nečistot v DMC, než jaké by bylo možné dosáhnout každým z těchto přístupů samostatně.</p><h3><strong>Proč je charakterizace nečistot v DMC náročná</strong></h3><p>Rozpouštědla určená pro výrobu baterií vyžadují detekci kontaminantů v širokém koncentračním rozsahu – od hlavních vedlejších produktů až po sloučeniny přítomné ve stopových koncentracích. V DMC mohou nečistoty zahrnovat kyslíkaté sloučeniny, uhlovodíky a nitrily, z nichž mnohé vznikají během syntézy nebo při manipulaci se vzorkem.</p><p>Tyto sloučeniny mohou koeluuovat nebo se vyskytovat v koncentracích pod běžnými detekčními limity, což ztěžuje komplexní analýzu pomocí jediné analytické techniky. Hmotnostní spektra získaná elektronovou ionizací (EI) navíc vždy neposkytují jednoznačný molekulový ion, což komplikuje identifikaci sloučenin.</p><h3><strong>Komplementární analytická strategie: citlivost + spolehlivost&nbsp;</strong></h3><p>Aplikační poznámka demonstruje kombinovaný pracovní postup využívající:</p><ul><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.cz/products/1097"><strong>Pegasus BTX (GC-TOFMS) </strong></a>pro vysoce citlivou detekci</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.cz/products/38"><strong>Pegasus HRT (vysokorozlišovací GC-MS)</strong></a> pro potvrzení pomocí přesné hmotnosti</li></ul><p>Systém<strong> Pegasus BTX</strong> umožňuje detekci nečistot <strong>pod úrovní jednotek ppb</strong>, takže zachytí i analyty přítomné ve velmi nízkých koncentracích.</p><p>Následně systém <strong>Pegasus HRT</strong> poskytuje data o přesné hmotnosti s vysokým rozlišením v režimech EI i pozitivní chemické ionizace (PCI). Režim PCI je obzvláště užitečný v případech, kdy spektra EI neobsahují jednoznačný molekulární iont, protože umožňuje identifikaci prostřednictvím běžných aduktů, jako jsou protonované molekulární ionty [M+H]⁺.</p><p>Jelikož jsou oba ionizační režimy dostupné bez hardwarových změn, podporuje tento pracovní postup efektivní, vícerozměrnou identifikaci analytů.</p><h3><strong>Pozorování</strong></h3><p>Pomocí tohoto kombinovaného přístupu bylo ve vzorku DMC identifikováno několik tříd nečistot. Patřily mezi ně:</p><ul><li>Kyslíkaté vedlejší reakční produkty</li><li>Alkoholy, karbonáty a ethery</li><li>Uhlovodíky a aromatické sloučeniny</li><li>Další nízkoúrovňové analyty detekované s vysokou shodou s knihovními spektry</li></ul><p>Vysoká citlivost systému Pegasus BTX umožnila odhalit širší spektrum sloučenin přítomných i ve velmi nízkých koncentracích, zatímco systém Pegasus HRT zvýšil jistotu jejich identifikace díky přesnému měření hmotnosti a potvrzení sumárních vzorců.</p><p>Studie rovněž ukazuje případy, kdy byly úspěšně dekonvoluovány koelující sloučeniny, což umožnilo identifikovat jednotlivé komponenty i bez jejich úplného chromatografického rozlišení.</p><h3><strong>Proč je to důležité pro analýzu bateriových materiálů</strong></h3><p>Tato práce ilustruje klíčový princip pokročilé charakterizace materiálů: detekce a identifikace představují dvě odlišné analytické výzvy, které často vyžadují komplementární řešení.</p><ul><li>Samotná detekce není dostačující bez spolehlivé identifikace</li><li>Vysokorozlišovací GC-MS může potvrdit identitu sloučenin jen tehdy, pokud jsou i složky přítomné v nízkých koncentracích nejprve spolehlivě detekovány.</li></ul><p>Kombinace těchto schopností poskytuje laboratořím hlubší vhled do čistoty rozpouštědel, výrobních procesů i potenciálních rizik, která mohou ovlivnit výkon bateriových systémů.</p><h3><strong>Prozkoumejte kompletní studii</strong></h3><p>Tento stručný přehled zdůrazňuje pouze část zjištění.

<p><strong>PFAS &amp; Our Planet is a webinar series on PFAS testing in environmental samples, food and food contact materials, textiles and other materials. Alongside the laboratory and regulatory lens, the series addresses the broader planetary impact of PFAS, including their persistence and movement through water, soil, air, food systems, and materials. It brings together what laboratories and industry need to understand now: where PFAS rules are heading, which sample types are under increasing focus, what needs to be measured, and how those needs translate into method selection, workflow setup, and result reporting.</strong></p><h4><strong>Webinar Series Details</strong></h4><ul><li>One registration to attend the full three-part series</li><li>Questions for experts in advance and/or live Q&amp;A</li><li>Access to recorded sessions provided</li></ul><h4><strong>Who Should Attend:</strong>&nbsp;</h4><p>Environmental and water testing laboratories, food testing laboratories, food contact material and packaging laboratories, textile and materials testing laboratories, contract testing laboratories, public sector and regulatory laboratories, manufacturers of food, packaging, textiles, and consumer goods, quality, product safety, regulatory affairs, and sustainability functions, and research laboratories working on PFAS analysis.</p><h4><strong>Recommended for:&nbsp;</strong></h4><p>Analytical chemists, laboratory managers, QA/QC managers, regulatory affairs managers, food safety and product safety managers, environmental scientists, packaging and food contact materials specialists, textile and materials testing leads, sustainability and product stewardship managers, validation and method development scientists, and technical leaders in contract, public sector, and research laboratories.</p><h4><strong>Regulatory context covered:&nbsp;</strong></h4><p>EU and U.S. PFAS developments, food contact and packaging measures, environmental monitoring frameworks, OEKO-TEX requirements for textiles and materials, Singapore’s food and water surveillance activity, India’s draft PFAS-related packaging amendment, and emerging movement in parts of Southeast Asia like Thailand, Malaysia, Vietnam, Indonesia, Bangladesh and Philippines.</p><h3><strong>Textiles and Materials</strong></h3><p><strong>Textiles and treated materials are facing stronger PFAS scrutiny as product restrictions widen and supply chains are asked to verify material content more clearly.

<p><strong>We probably have all experienced this at some point when performing gas chromatography and our peak shape begins to appear a bit different. &nbsp;In this webinar, we will discuss some of the most common chromatographic issues that you experience with Gas Chromatography and take a logical approach to finding the root cause and correcting the problem. Often the best way to approach troubleshooting is to also consider what ‘cannot’ cause an issue so that precious time is not spent addressing something that cannot cause the issue. This webinar will arm you with some simple tools, and a different way to look at troubleshooting, should a problem arise.</strong></p><blockquote><p><strong>Speaker:</strong> Alex Ucci&nbsp;</p><p>In his current position at Agilent, Alex provides application assistance and technical support for sample preparation products as well as GC and LC consumables.
