New PID Now Available for EPAAnalyses

- O.I.C. Advances GC Detector Technology New PID Now Available for EPA Analyses O.I. Corporation has developed a new photoionization detector engineered specifically for use with the electrolytic conductivity detector. This new detector has many features not found in any other PID including:

the Advantage in Performance and Flexibility

• Hidden window design prevents sample from contacting and fouling lamp window • Unitized, combo PID/E1CD detector system formed when joined to the E1CD Or

• Only one detector port required for PID/E1CD combo system • No transfer line required for serial inter­ face to E1CD • LampSaver circuit extends lamp life • Custom designs for specific GC models fit into standard detector ports • Detector vent for venting unwanted eluates priot to detector chamber

True capillary performance for EPA 601/602 analyses
