PEAK PERFORMER 1 PDD (930 Series)
Highly sensitive Pulse Discharge Detector (PDD).
The Peak Performer 1 PDD uses a highly sensitive Pulse Discharge Detector (PDD) which has been designed specifically for process applications in UHP gases.
The PDD is used to measure trace impurities down to part per billion levels, while offering a common 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.
