Important:
A continuous carrier gas supply is required for error-free operation (frequent carrier gas failure has a negative effect on the life cycle of the detectors and the device-internal pressure regulator). In addition, an external two-layer pressure regulator for the carrier gas pressure is strongly recommended.
