Liquid-liquid extractions have usually been performed manually. But now your autosampler can do your extractions for you before sample injection.
Extracts can leave matrix residues in GC liners, complicating results. The new MPS Robotic automates liner exchange, improving analytic results.
GERSTEL’s new MPS Robotic represents the latest, most versatile in autosampler technology, with advanced software that simplifies sample preparation.
The inventor of stir bar sorptive extraction (SBSE) recalls the creation and adoption of the Twister. The technology is now a standard method worldwide.
Here’s what researchers at General Mills found when they used the GERSTEL SBSE Twister to clean up QuEChERS extracts during analysis of pesticides in food.
The liner of your gas chromatography equipment must be changed frequently, due to matrix residue buildup. Do it faster with automated liner exchange.
The determination of opioids, cocaine, and metabolites from blood serum is a routine task in forensic laboratories. Typical methods include many manual or semi-automated steps like protein precipitation, dilution, solid phase extraction, evaporation, and derivatization preced¬ing GC/MS or LC/MS analysis.
Gas chromatography–mass spectrometry (GC/MS) has been an indispensable technique for identification of volatile compounds. However, one dimensional GC in combination with low resolution mass spectrometry is often insufficient for unequivocal identification of important trace components in complex samples like natural products due to...
