If this condition is met, then analysis may proceed. The data quality objective for the continuing calibration check standards is 85-115%.

Leak Detection Methods - Thomasnet
cdn.thomasnet.comJan 01, 2001 · gas detectors (halogen, helium and hydrogen). The first three techniques, due to their characteristics and sensitivity, can be used only for gross leak detection (300 g/y (10.5 oz) or more refrigerant leakages). Tracer gas leak testing methods are much more precise than the previous group but, in many cases, their theoretical

Substitutes: There is no substitute for helium in cryogenic applications if temperatures below –429 °F are required. Argon can be substituted for helium in welding, and hydrogen can be substituted for helium in some lighter-than-air
