Gas Chromatography – Multimedia

There is a growing demand for more rapid methods with maintained robustness and chromatographic performance for the identification and quantitation of chemical residues in food analysis.

The increasing global demand for food has led to a growing use of pesticides, resulting in elevated risks of trace level chemical pollutants in food. Rapid and reliable methods are required to identify and quantify these pollutants with high sensitivity and over a wide dynamic range.

The advanced, built-in robotics of the Thermo Scientific™ TriPlus™ RSH SMART Autosampler deliver exceptional precision, sample handling flexibility, and reliable unattended operation.

Gas chromatography (GC) is a valuable analytical tool used to separate, quantify, and identify compounds of interest. This infographic explores the best ways to optimize the operating efficiency of GC systems and ensure cost-effective productivity in the lab.

Speaking at Advances in Food and Beverage Analysis 2021, Andrea Hochegger from Graz University of Technology, presented her talk on mineral oil hydrocarbons in food.

The sample preparation workflow for pesticide analysis can be accelerated through automation with possible on-line or off-line injection into the chromatographic system. The video focuses on the automated clean-up step of QuEChERS extracts through the microSPE technology using the Thermo Scientific™ TriPlus™ RSH or RSH SMART autosamplers.

Increasing automation in your daily sample handling workflows enables more unattended operations. It means enhanced productivity, higher accuracy and precision, greener solution for reducing sample volume and solvent waste, including less human hazardous exposure.

If your gas chromatograph is only running part time, you’re missing the benefits of a system that delivers measurably more production time. That’s the advantage of the time- and space-saving Thermo ScientificTM TRACETM 1600 Series Gas Chromatograph (GC).

Ensuring food safety and quality is increasingly challenging. Whether you're analyzing for pesticide residues, ensuring that label claims are correct and accurate, or profiling for food authenticity, you need a system that delivers low detection levels and high sensitivity.

Since the separation of compounds by GC is governed by a molecule’s partitioning properties between the carrier gas and the column’s stationary phase, the careful selection of which column to use not only impacts chromatographic performance, but sample throughput and capacity as well.
