P e r f o r m a n c e is t h e K e y For years GOW-MAC's simplified gas c h f o m a t q g r a p h s have been m a k i n g a strong impact oh a demanding field. B o t h thermal conductivity and flame ionization detector models are offered. Recently the microprocessor has brought a higher level of temperature programming capability to the analytical technique. Yet GOW-MAC's price remains low while the quality stays high. In all cases, the GOW-MAC gas chromatograph consists of a superlative detector encased in an instrument designed to optimize the performance of the detector. The more sophisticated instrum e n t s may look pretty, but we don't For Microprocessor Programming, Circle 66

Microprocessor Programming We've added a microprocessor-controlled temperature programmer t o our standard thermal conductivity GC t o create the 5 5 0 P , on the left. The 6 9 - 7 5 0 P dual flame microprocessor controlled GC is also available. You can program t i m e , temperature and ramps; all at the push of a few b u t t o n s . Each instrument handles routine analyses
