Spectra Analysis’ DiscovIR GC-FTIR focuses on real-time connection of Infrared Spectroscopy to Gas Chromatography. This instrument is now also available through JSB in Europe who is able to deliver complete GC FTIR system solutions for the specific application areas. Temperature controlled, vacuum deposition of the GC eluted peaks onto a rotating IR-transparent disc...
If you have ever tried to measure formaldehyde by GC using an FID, you will have noticed that the response you get is significantly lower than you might have expected. The flame ionization detector (FID) is the most widely used detector in gas chromatography. It is extremely sensitive with a wide linear range for most organic compounds. However, compounds such as oxygenates, ethers, amides and other organic compounds containing heteroatoms (e.g. O, N, S, Cl, Si), generate a lower or sometimes negligible response....
3-Monochloropropane-1,2-diol (3-MCPD), 2-monochloropropane-1,3-diol (2-MCPD) and glycidol are known as contaminants in foodstuffs due to manufacturing. MCPD fatty acids may occur during the refinement process of oils and fats at high temperature or in the presence of chloride containing salts. However, refinement is an essential chemical and physical process. Only through this kind of treatment with high temperature undesired odorants and flavoring substances as well as possible traces of toxic compounds (pesticides, heavy metals or mycotoxins)...
GCxGC-MS is the ideal analytical technique to accommodate the complexity of the samples due to its enhanced peak capacity and sensitivity. For quantitative purposes, and when using flow modulation, splitting to a FID is a logical choice. Sample preparation and sample introduction introduce further challenges due to the complex nature of the samples....
