Gas Chromatograph – Flame Ionization Detector

     
     
     

Model/Series

  • Agilent Technologies 6890N
  • Shimadzu GC-14A (FID,NPD)
  • Shimadzu GC-14B
  • Shimadzu GC-8A

 

Detector

  • Flame Ionization Detector

 

Descriptions

Gas chromatography is a useful technique for chemicals separation. In gas chromatography different components of the mixture is separated in GC column. Most columns cannot withstand temperatures greater than 250-350 °C. A sample is rapidly heated and vaporized at the injection port. The sample is transported through the column by a mobile phase consisting of an inert gas. Sample components are separated based on their boiling points and relative affinity for the stationary phase, which is most often a viscous liquid (wax) within the column. The higher a component's affinity for the stationary phase, the slower it comes off the column. The components are then detected and represented as peaks on a chromatogram.

High Performance Liquid Chromatography (HPLC)

     

Model/Series

  • Agilent 1100 Series

 

Detector

  • Diode array detector and Fluorescent detector

 

Descriptions

High performance liquid chromatography is now one of the most powerful tools in analytical chemistry. It has the ability to separate, identify, and quantitate the compounds that are present in any sample that can be dissolved in a liquid. HPLC can be, and has been, applied to just about any sample, such as pharmaceuticals, food, cosmetics, environmental matrices, forensic samples, and industrial chemicals.
