Gas chromatography detectors

There are many detectors available for GC (see Table 1). These detectors can be divided into two categories: general detectors and selective detectors. Let’s discuss one after the other the detectors mentioned in table 1 The thermal conductivity detector (TCD): This is a general detector that can be used for both organic and inorganic compounds. It produces a …

BALANCES

The history of balances and scales dates back to Ancient Egypt. A simplistic equal-arm balance on a fulcrum that compared two masses was the standard. Today, scales are much more complicated and have a multitude of uses. Applications range from laboratory weighing of chemicals to weighing of packages for shipping purposes. To fully understand how …

Flame Ionization Detector (FID)

A flame ionization detector (FID) is a scientific instrument that measures analytes in a gas stream. It is frequently used as a detector in gas chromatography. The measurement of ion per unit time make this a mass sensitive instrument.Standalone FIDs can also be used in applications such as landfill gas monitoring, fugitive emissions monitoring and internal combustion engine emissions measurement in stationary or portable instruments. Fig 1: FID. …

LABORATORY ACCREDITATION AND CERTIFICATION PART 1

According to NIST, The terms “accreditation” and “certification” are sometimes used interchangeably, however, they are not synonymous. Certification is used for verifying that personnel have adequate credentials to practice certain disciplines, as well as for verifying that products meet certain requirements. Accreditation is used to verify that laboratories have an appropriate quality management system and …
