Abstract
Usually, a sniffing leak detector must be calibrated for each tracing gas. The calibration comprises ranging of the spectral positions into the mass spectrum and the amplitude height. At least one mass line is determined with a calibrating gas. The mass lines lying between two mass lines and/or between a zero point and a line are determined by interpolation and/or extrapolation. In this manner, a sniffing leak detector can be used for such tracing gases which have not previously been used for calibration purposes.
