Abstract

A new apparatus for fast gas chromatography separations is described. It consists of a small volume oven containing a coiled fused silica capillary column that is heated by a flow of hot air. The oven can be heated at rates of 10 °C s−1 with a 300 W heater. Benchmark studies at various temperature programming rates are described. Retention time relative standard deviations increase with increasing heating rate, but are at most about 1% when an 8 °C s−1 heating rate is employed. The small size of the column oven makes it possible for it to be attached to a commercial GC instrument through an opening provided for installation of a second injector.
