In this article, the authors describe a pyrolysis technique that is based on the injection of polymer emulsions or solutions using a high-temperature PTV system.
A novel approach for determining the structure and composition of polymers has been developed by scientists at Dow, a leading producer and supplier of chemicals and polymer products. In this article, the authors describe a pyrolysis technique that is based on the injection of polymer emulsions or solutions using a high-temperature PTV system. This approach enables efficient automation and improved determination of pyrolysis breakdown products using GC-FID or GC–MS.
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.
