Columns designed for both polar and non-polar molecular species are available.
The detector is a HP Model 5970 quadrapole mass spectrometer, and the lookup catalog contains about 50,000 compounds. The GC has an autosampler. However, ECD samples must not be dissolved in any solvent that contains halogens. Organic and inorganic compounds that are non-volatile with very low vapor pressures below about 600 o C or compounds that decompose at elevated temperatures. Approximately 20 m L of sample solution are necessary for each run.
