1. Documentation verification and sample inspection is completed through visual checks to ensure proper sample conditioning and no evidence of malfunction or sample loss. 2. Filter conditioning is controlled for each sample by repeating conditioning for 24 hours under chamber conditions controlled within 5% relative humidity and 1 degree Celsius temperature, using a humidity chamber with saturated chemical solution at 25 degrees Celsius. 3. Gravimetric analysis is conducted to the nearest milligram after conditioning and weighting is repeated under controlled conditions then reported to a supervisor.
