ABSTRACT:
A liquid separator for removing liquid from a breath sample comprises a liquid trap having a conduit passing the breath sample and opening through a check valve to reservoir chamber. Sample flow is diverted to the reservoir and ambient air is drawn back through the conduit and check valve to backflush liquid in the conduit to the reservoir. The reverse flow is activated by the presence of liquid in the sample line, periodically actuated by a timer or both. The reverse air flow may be used as a zero calibration gas for an infrared analyzer.
