The gas chromatographer works by injecting a gas into a heated column in which the volatile substances are separated by their arrival times, at the opposite end of the column. The amount it takes for the substance to move through the column is known as the retention time. Though most Gas chromatographer systems are extremely expensive, costing between $500 - $50,000 dollars, they can be simply made with at home products. Using activated tide as the stationary phase in the column, and a gas- lit copper coil, the retention times of various halogenated hydrocarbons which react with the copper, can be determined. When the gas reaches the copper coil, the result is a colored flame, known as the determined....
