Components of different concentrations are often found in food aroma profiles, but compounds that are odour- active are usually present in small amounts. Hence it is important to ensure that all ...

Headspace sampling is an ideal way of introducing a sample into a GC. It avoids the introduction of involatile or high-boiling contaminants from the sample matrix and it can often be used for the ...

Routine testing and quality control (QC) laboratories can enhance the performance of daily workflows with access to an advanced static headspace sampling system that is expected to provide high ...

Agilent Technologies Inc. introduces a network headspace sampler that features an inert sample pathway and significant improvements in sensitivity, performance and productivity. Agilent's newest ...

Airborne chemical signals emitted by bacteria influence the behavior of other bacteria and plants. We present an overview of in vitro methods for evaluating bacterial and plant responses to bacterial ...

Headspace sampling is compared with purge-and-trap techniques for the gas Chromatographie (GC) analysis of volatile pollutants in water. An objective comparison of the two sample introduction ...

A recognizable response pattern is produced by conventional electronic noses (eNoses), using a range of dissimilar, but not specific, chemical sensors. Though eNoses have interested developers of ...
