Agilent J&W Packed GC Columns are designed and manufactured to offer excellent and reproducible performance for all sample types associated with packed column separations, most important in the ...

As long ago as 1956, Dr. A. J. P. Martin pointed out 1 that operation of thermal conductivity detectors at reduced pressures should enable them to measure samples at the µg-level and he states that ...

During one-dimensional gas chromatographic (1D-GC) analyses of complex biological, environmental, or petrochemical samples, the outcome is often a chromatogram that has a huge portion of unresolved ...

Chromatography is an analytical technique that is used to separate mixtures by distributing the components of a mixture between a stationary phase and a mobile phase. Columns are used in various types ...

A RECENT development in gas Chromatography is the use of columns made from metal capillary tubing, the inner surface of which is coated with a thin layer of stationary phase 1. These columns promise ...
