7.6.12 Certification Procedures of Working Standards

The NO content of the NO working standard must be periodically assayed against NIST-traceable NO or NO2 standards. Any NO2 impurity in the cylinder must also be assayed. Certification of the NO working standard should be made on a quarterly basis or more frequently, as required.

Procedures are outlined below for certification against NO traceable standard. The simplest and most straightforward procedure is to certify against a NO standard.

NOTE

If the assayed concentration of NO2 impurity in the NO cylinder, [NO2]imp, is greater than the 1 ppm value allowed in the calibration procedure, make certain that the NO delivery system is not the source of contamination before discarding the NO standard.
