whatever your gas chromatography need, Beckman has the precise answer! A t Beckman, you'll find the most complete line of laboratory gas chromatog r a p h s available—the best solution to a n y analysis problem. There's a model j u s t r i g h t for you. The Beckman GC-2A is the most sensitive of commercial gas c h r o m a t o g r a p h s . I t provides t h e r m a l conductivity detection with a sensitivity ten times g r e a t e r t h a n t h a t of previously available i n s t r u m e n t s . Used with the Beckman F l a m e Ionization Detector, p a r t s per 1,000,000,000 ultrasensitivity is obtained. Or add the T h e r m o t r a C , most precise of t e m p e r a t u r e p r o g r a m m e r s , for an infinite v a r i e t y of linear, non-linear, and step-function p r o g r a m s . Other GC-2A accessories include Dual Column Valves, S t r e a m Splitter Kit, T e m p e r a t u r e Readout, and F r a c t i o n Collection System. F o r routine analytical -work, consider the low-cost GC-1 or the more versatile GC-2...both of which deliver 5 p p m sensitivity a n d 0.19c reproducibility. F o r increased speed and efficiency, the GC-1 accommodates Dual Column Valves, and the GC-2 the full line of Beckman accessories.

The Beckman Megachrom combines analytical and p r e p a r a t i v e functions, and is the only t r u e research p r e p a r a t i v e gas chromatograph commercially available. Its introduction h a s led to a complete review of the traditional concepts of compound p u r i t y . The Megachrom offers a practical method for collecting large quantities of p u r e compounds from a complex mixture, while delivering resolution comparable to analytical instruments.
