You have more a d v a n t a g e s with t h e Barber-Colman Detectors: BROAD RANGE — N o t only analyzes chlorinated a n d thiophosphate pesticides b u t can also be used for other halogenated compounds, nitriles, nitrates, organo-metallics, conjugated carbonyls, steroid a n d amino acid derivatives. FLEXIBILITY — Electrode spacing in t h e Barber-Colman design is adjustable from 1 t o 25 m m . You h a v e optimal control of a t t a c h m e n t phenomenon. I t is usable with either packed or capillary* columns. *Golay p a t e n t 2920478 HIGH SENSITIVITY — 1 centimeter inside diameter permits source strength of 300 millicuries of tritium, providing detection of picogram a m o u n t s (10 -15 mole/sec. or better in m a n y cases).
