The Series 590 DID GC contains a single, GOW-MAC® patented. discharge ionization detector (DID) which is non-radioactive, universal, and concentration dependent. The detector uses an electrical discharge in helium to generate high energy UV photons and metastable helium which ionizes all compounds except helium.
- The Series 816 GC combines the industry's leading digital GC platform with GOW-MAC®'s advanced detector technology. 1999 GOW-MAC opened an office in Taipei, Taiwan.

Introduction
You will be given mixture of unknown composition for this lab. It will contain several organic compounds with similar boiling points diluted in acetone. You need to (1) determine how many components there are in the mixture, (2) determine the percent composition for each compound, and (3) determine the relative polarities of the compounds.
Gow Mac Gc Manual
There are two gas chromatographs available for this task, and your goal is to determine which works best. You will run the sample on both instruments and compare their performance. Specifically, one lab partner will use a Gow-Mac 150-series isothermal gas chromatography and the other will use a Gow-Mac 400-series. Both use thermal conductivity detectors (GC-TCD) and work on the same principles. They separate compounds by both boiling point and polarity, and produce a peak for each component wherein the peak area is proportional to the amount of that component present.
Before coming to lab you should be familiar with the concepts presented in the following videos:
