High sensitivity GC measurements & amp detection.

The Peak Performer 1 TCD uses a sensitive single filament Thermal Conductivity Detector (TCD) which has been designed specifically for process gas or laboratory applications.

The TCD is used to measure impurities or mixtures from ppm to percent levels. The PP1 TCD uses Peak Laboratories proven operating platform for simple, accurate measurements. The PP1 technology has proven to offer a more cost-effective and user friendly alternative to other process GC's. In addition, Peak Labs practical experience and ability to customize to suit your applications makes Peak Labs your partner, not just your supplier.
