How to Read a Chromatogram? – Lab-Training.com

Real Chromatogram. The ordinate is in units of volts and abscissa in minutes. The signals are recorded at a wavelength of 284 nm using a UV detector. Retention time of each peak is marked above the peak and in the tabulated data below the chromatogram details of the retention time, area (as digital units), peak area%, height and height %.

Analytes: Organic, Inorganic, Must be volatile


GAS-LIQUID CHROMATOGRAPHY. Gas-liquid chromatography (often just called gas chromatography) is a powerful tool in analysis. It has all sorts of variations in the way it is done – if you want full details, a Google search on gas chromatography will give you scary amounts of information if you need it!

How is Gas Chromatography Used in Forensics

Gas chromatography is the process whereby the various elements of a compound are separated into their distinct parts for individual analysis. This is most often achieved by observing how the elements react with a specific solvent and identifying them by their unique “retention time”.

Gas Chromatography – Chemistry LibreTexts

Gas chromatography is a term used to describe the group of analytical separation techniques used to analyze volatile substances in the gas phase. In gas chromatography, the components of a sample are …

How do I analyze the results from gas chromatography (GC-TCD)?

A method comparison between gas chromatography-thermal conductivity detector (GC-TCD) and chromatography-flame ionization detector (GC-FID) for the analysis of …

Gas Chromatography – an overview | ScienceDirect Topics

Gas Chromatography. Gas chromatography (GC) is a technique used for the analysis and quantification of volatile compounds. Compounds are injected onto the gas chromatograph and flash evaporated onto the column. This can be done using a packed or capillary column. The column is the stationary phase and the gas is the mobile phase.

Gas chromatography–mass spectrometry – Wikipedia

The GC-MS is composed of two major building blocks: the gas chromatograph and the mass spectrometer. The gas chromatograph utilizes a capillary column which depends on the column’s dimensions (length, diameter, film thickness) as well as the …
