Highest sensitivity laboratory chromatograph...the
New Beckman
GC-2A.
T h e GC-2A employs t h e most sensitive thermal conductivity detector to be found in a n y commercially available laboratory gas chromatograph. Extremely stable, full-proportional t e m p e r a t u r e control over a wide range is combined with a precise carrier gas flow control system to provide exceptionally reproducible retention volumes and peak heights. T h e 2A functions economically and efficiently in a broad range of applications from routine qualitative analyses to the detection of low, 0.5 p p m . concentrations encountered in trace analyses, a n d in high efficiency, fast analysis techniques t h a t use small samples. 53 An ultra-sensitive Hydrogen Flame Detector, shown above, t h e new B e c k m a n Stream Splitter for optimizing column efficiency, micro liquid sampling a p p a r a t u s for highly reproducible samples, and over 100 different s t a n d a r d !4", and '/s"packed columns... make this t h e most versatile of a n y commercial laboratory gas chromatograph.
