Abstract Analysis of organic compounds in samples characterized by different composition
of the matrix is very important in many areas. A vast majority of organic compound …

In recent years, the need for measurement and detection of samples in situ or with very small
volume and low concentration (low and sub-parts per billion) is a cause for miniaturizing …

Separation of complex gaseous mixtures using gas chromatography (GC) is an important
process in analytical systems for environmental monitoring, medical diagnosis, and forensic …

The key to rapid temperature programmed separations with gas chromatography are a fast,
low-volume injection and a short microbore separation column with fast resistive heating …

Almost four decades of investigations have opened up many avenues to explore the
production and utilization of planar (ie, microchip) gas chromatographic columns. However …

Miniaturization in analytical chemistry is a clear trend, and has been the subject of an
important number of research works. In this article, we present a general overview of the …

We developed a fully automated portable 2-dimensional (2-D) gas chromatography (GC x
GC) device, which had a dimension of 60 cm× 50 cm× 10 cm and weight less than 5 kg. The …

Many microfabricated gas chromatography (micro-GC) column designs have been reported
so far, but it is unclear how microcolumn design affects separation performance in the typical …

Homovanillic acid (HVA), vanylmandelic acid (VMA), and 5-hydroxyindoleacetic acid (5-
HIAA) are the metabolites of some catecholamines such as epinephrine, nor-epinephrine …

This article demonstrates how to prepare microfabricated columns (microcolumns) for
organophosphonate and organosulfur compound separation that rival the performance of …
