Chromatographic techniques are an important tool in chemical analysis. Our new Gas Chromatograph BT45i is a low-cost gas chromatograph, intended for educational use. It is designed to separate mixtures of gases or volatile liquids and identify components of the mixtures by their specific retention times. Air from an air pump is used as carrier gas. The GC operates at room temperature, eliminating long warming-up periods. 
The CMA GC BT45i is delivered with a non-polar column, air pump, 9V power adapter, three syringes incl. short needles, two spare septa, 40-cm PVC tubing, and a disposable cigarette lighter.
