Pixabay/Filmbetrachter: Pyrolysis GC-MS for the analysis of microplastic in biota samples

Join this webinar and learn about a solution for microplastic and nanoplastic analysis using pyrolysis in combination with single quadrupole GC-MS or high resolution GC-MS.

In this webinar, you will:

  • understand the workflow for biota (salmon) from sample preparation to a quantitative result
  • hear how pyrolysis in combination with GC-MS technology provides a fully automated workflow and the required selectivity and quantification abilities for the detection of microplastics
  • learn how software tools support you to gain the required selectivity for microplastics and to quantify results

This webinar is relevant for:

  • researchers from the food and environmental field
  • control and governmental labs
  • plastic manufacturers that are interested to understand more about the degradation of their products
  • cosmetic industry or research and control labs for this industry

Microplastic are particles of 1µm to 5mm and turned into an an emerging issue all over the globe. The intake into the environment can derive from different sources such as laundry effluents, car tires, plastic waste to name a few. Microplastic is found in soil, air and water. Here is an example to give an impression of magnitude of microplastic in the marine environment: 4.8 million tons of plastic waste enter the world's oceans each year (1). They degradate and can enter as micro- or nanoplastic into the food chain. The degradation of microplastic makes it more risky since nanoplastic (particles smaller than 1 µm) can go directly into human cells.

In addition to their presence which is already of concern, they can adsorb other pollutants like persistent organic compounds (POPs) on their surfaces. These hydrophobic organic chemicals adhere to the microplastic particles and reach concentrations up to 1 million times higher that of the surrounding medium (e.g., water) (2). The particles may enter the stomach and release the POPs, which accumulate in fat cells.

The goal of researchers is the determination of the micro- and and nanoplastics, their composition and quantities, as well as their degradation products and their source of origin. To identify the kind of plastic like polyethylene (PE) or polyamid-66 (Nylon66), spectroscopic techniques such as FTIR can be used. If quantification or detection of nanoplastic are required, pyrolysis in combination with single quadrupole GC-MS comes into place. For more detailed information, such as degradation products or isotopic ratios for the determination of source of origin, high-resolution-MS is the technology the technology of choice.

Presenter: Dr. Michael Soll (European Business Development Manager, Frontier Laboratories Ltc.)

Michael Soll studied biology and received his PhD in 1993 at Ruhr University Bochum, Germany.

He has over 25 years of experience in business development, marketing and sales at various companies active in analytical instrumentation and analytical services in Europe. His functional experience included marketing, application and sales of LC- and GC-coupled mass spectrometry, MALDI-TOF MS and chromatographic tools. End of 2014, he joined Frontier Laboratories, a global leading company in GC/MS coupled analytical pyrolysis. Here, he is managing and supporting distribution partners and supports users of analytical pyrolyzers in whole Europe in terms of applications and technical concerns.

His most recent employment history is as follows:

Frontier Laboratories Ltd, Koriyama, Japan, 2014 to present as European Business Development Manager, responsible for support of distribution partners and users in Europe, marketing directed to sales channels and customers

LECO Germany, Mönchengladbach, Germany, 2008 to 2014 as Managing Director, responsible for achievement of sales targets, strategic directions, marketing and service optimization

SGS, Geneva, Switzerland, 2006 to 2008 asBusiness development manager biopharma quality control Europe.

ABSciex, Darmstadt, Germany, 1999 to 2006 asSales Manager Proteomics products in DACH territory: increase sales of Mass Spectrometry and Chromatography products

Presenter: Petra Gerhards (EMEA Regional Marketing Manager GC&GC-MS, Thermo Fisher Scientific)

Petra holds a diploma engineer in instrumentalized analytical chemistry from the Technical University Krefeld/Germany. For more than 30 years, she worked in the field of GC and GC-MS and covered many technologies in GC and GC-MS. Currently, she supports users and customer application teams all over EMEA in her position as EMEA Regional Marketing Manager.
