The faculty of Engineering Technology at the University of Twente has set its research objectives on following model reactions and model vulcanization (vulcanization being the chemical process of hardening rubber). In order to achieve those objectives the university have chosen Peak gas generators to help them with their analysis. A. van Swaaij, a technician within the faculty, tells us about he ...
Ideally the oil analysis should be performed without any sample preparation to reduce the test time, as well as maintain the integrity of the oil sample. ...
Fats itself cannot be transferred into the gas phase to use an easy GC approach. So a lot of techniques are standardized from organizations like AOAS, ISO or DGF to cut the fats into glycerine and its fatty acids, followed by derivatization of the fatty acids into their Fatty Acid Methyl Esters (FAME) for further GC measurement. ...
Split ratio flexibility of GC injector increased 30-fold A leading manufacturer of analytical sample preparation systems in gas chromatography (GC) switched to Axetris MFCs - and in doing so, simplified their product range, while offering their customers at least 30 times more flexibility in split ratio. The market-leading dynamic range of ...
Headspace GC allows the quantitative analysis of alcohol directly from blood samples. Standard headspace systems use nitrogen for vial presurization, with helium typically used for GC carrier gas. ...
Here we tested fresh strawberries and spinach purchased from both an Amish farm and a local grocery store to determine if pesticide residues were present. We used a QuEChERS-based sample preparation method and gas chromatography-time of flight mass spectrometry (GC-TOFMS) for analyzing pesticides. ...
The use of carbons in sample preparation techniques such as solid phase extraction (SPE) and air sampling has been ongoing for several decades. Recent advancements in sample preparation techniques have led to the use of carbons in micro-SPE (i.e., pipette tips packed with particles), solid phase microextraction ...
