The increasing need for even more sensitive analyses of harmful substances brings new pressure on gas chromatography (GC) analytical methods.
The increasing need for even more sensitive analyses of harmful substances brings new pressure on gas chromatography (GC) analytical methods. Flow path inertness is the next frontier in the continuous improvement of GC analyses. The ongoing development of ultra-inert inlets, columns and detectors - alongside test mixes and procedures that assure a highly inert flow path - is improving the ability to analyse difficult, active compounds present in trace amounts.
Next Generation Peak Fitting for Separations
December 11th 2024Separation scientists frequently encounter critical pairs that are difficult to separate in a complex mixture. To save time and expensive solvents, an effective alternative to conventional screening protocols or mathematical peak width reduction is called iterative curve fitting.
Identifying and Rectifying the Misuse of Retention Indices in GC
December 10th 2024LCGC International spoke to Phil Marriott and Humberto Bizzo about a recent paper they published identifying the incorrect use of retention indices in gas chromatography and how this problem can be rectified in practice.
