Agilent Technologies Inc. (NYSE: A) and Shimadzu Corp. today Aug. 20) announced the release of each other’s GC instrument control for their respective chromatography data systems. The move provides customers in analytical laboratories with more freedom of choice when selecting a chromatography data system.

Criminals are smuggling an estimated $30 billion in U.S. currency into Mexico each year from the United States, but help could be on the way for border guards, researchers reported recently. The answer to the problem: a portable device that identifies specific vapors given off by U.S. paper money.

Get fun facts about laboratory GC systems, a list of questions to ask when buying these systems, the most recent GC product releases, and an updated GC system manufacturer's list in this section.

Novel program increases lab accuracy and unknown compound identification with single quadrupole instrumentation.

Chromatography data systems (CDS) are an integral component of any analytical laboratory. Yet, over time a CDS may no longer meet a lab's needs. This white paper from Waters details how to go about determining when you should replace your CDS.

Many labs use chromatography-based devices. Plus, different labs face different needs in handling chromatography data. Nearly any situation, though, benefits from a chromatography data system (CDS).

Researchers at the Georgia Tech Research Institute are developing a micro gas chromatograph for early detection of diseases in crops. 

Gas chromatography (GC) is a common technique used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. GC is typically used for separating the different components of a mixture, improving the purity of a particular substance, or identifying a particular compound. GC is a ubiquitous technique, and the various GC instruments available are designed to achieve every requirement of the technique.

"More laboratories are opting to generate their own gas, on-site," said John Speranza, Vice President of Global Sales at Proton OnSite.  "For Gas Chromatographers (GC) who are struggling to source inexpensive helium gas, hydrogen is the superior carrier gas alternative..."

Helium is commonly used as the makeup gas for flame ionization detection in gas chromatography;
however, dramatic increases in cost and limited availability in recent years have led many chromatographers to use nitrogen in its place.

For all its maturity and secure establishment in chemical analysis, predicting the future of gas chromatography is an exercise in uncertainty.

As regulators have redefined environmental methods for low-abundance analytes, and demanded the analysis of more analytes, column manufacturers have done well to provide greater sensitivity and selectivity.
