Peak Performer 1 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. Please contact us at Peak Laboratories or your local sales representative for custom applications and further information on our standard applications. The Peak Performer 1 PDD gas chromatograph (GC) has been optimized for nitrogen as an impurity in UHP gases to simplify the chromatography and consistency of the process application. Typical applications are in UHP process gases such as, Ar, O2, He, and H2. Performance * Some standard detection limits (in parts per billion)

Matrix Gas He Ar O2 H2 N2 N2O Impurity

N2: Nitrogen 1** 1** 1** 1** n/a 1- 5 Ar: Argon 1** n/a 1** 1** 1** n/a

- * All performance specifications can be optimized at best efforts for specific applications. - ** Contact local sales agent for quote if < 1 ppb LDL is required

• Unless specified, carrier gas is purified research grade helium.
