Isolation of
pure components, as small as 0.0002 cc, is made pos sible by the Beckman GC-2· Gas Chromatograph, u s i n g a new system of fraction collection. Pure, minute fractions are captured and condensed in a fluted glass tube, then transferred to microcells for infrared analysis or retained for other studies. Large samples can be introduced and fractionated with no loss of resolution, by using a unique large-column and time-controlled heated inlet. 33 These and other accessories — such as the new Dual Column Valve, Precision Liquid Sampler, Back Purge Kit, Largevolume Gas Sampling Assemblies and Interchange able Columns - offer new versatility and precision in gas chromatography. For details see your Beckman dealer or write for Data File L-43-15.
