Thermal Gradient Gas Chromatography (TGGC) employs dynamic temperature profiles along the chromatographic column to enhance separation efficiency and peak resolution. This technique, when ...

Portable devices just a little too big to hold in one hand are used today to analyze samples at crime scenes, fires, and other places where time is of the essence. The technology had its start 60 ...

After entering the vaporization chamber in gas chromatography, sample solution will enter the chromatographic column, transferred by the carrier gas (the carrier gas is usually nitrogen or helium).

In this article, we take a look at what gas chromatography is, how it works and how to interpret output data. Its combination with mass spectrometry and the use of multiple dimensions are considered. ...

LCGC International interviewed Bob Pirok from the University of Amsterdam, Netherlands to discuss strategies for enhancing ...

The stationary phase contains either a solid adsorbent, which is known as gas-solid chromatography or a liquid on inert support called gas-liquid chromatography. On completion of the analysis, GC ...

Elution in gas chromatography is monitored electronically by placing a detector at the outlet stream of the permeable column. This measures the retention time (tR) of compounds to qualitatively ...

Shimadzu Scientific Instruments, Inc. (SSI) has introduced the Automatic Adjustment of Retention Time (AART) function of GCMS solution 2.5 software to deliver time savings during analysis preparation ...

Thermal Gradient Gas Chromatography: A gas chromatography technique that uses spatial or temporal temperature gradients along the column to enhance resolution and reduce analysis times.
