ABSTRACT:
The apparatus, with a disposable cartridge, is connected into the sample-input-line of the to be calibrated moisture analyzer. The cartridge contains a substance with previously determined, chemically bonded, moisture content.
A motor-driven carriage with a heated section moves slowly along the cartridge, thereby heating a small portion of the cartridge up to a temperature causing the bonded moisture of the substance to release or liberate itself from the substance.
The moisture is then carried with the gas sample into the to be calibrated analyzer and the moisture content in the cartridge may be compared with the moisture determination obtained by the analyzer.
Moisture released from the substance at room temperature has been found negligible.
