FOR MEDICAL USE

Requirement Analytical Method Limit of Detection Specification Limit Result

Carbon Dioxide Assay (CO2) Speed of Sound 99.99 % 99.0 % 99.99%

Nitrogen Oxide (NO) IMR-MS 0.05 ppm 2.5 ppm ND

Nitrogen Dioxide (NO2) IMR-MS 0.1 ppm 2.5 ppm ND

Ammonia (NH3) IMR-MS 0.03 ppm 25 ppm ND

Sulfur Dioxide (SO2) IMR-MS 0.03 ppm 5 ppm ND

Hydrogen Sulfide (H2S) IMR-MS 0.03 ppm 1 ppm ND

Carbon Monoxide (CO) FTIR 0.05 ppm 10 ppm ND

Moisture (H2O) Quartz Crystal 0.5 ppm 200 ppm 0.77 ppm

Notes:

Positive Carbon Dioxide Identification is achieved when the Assay results demonstrate meeting the specification.
The limit of detection (LOD) for each test method is the threshold value for results to be reported with certainty in the accuracy of results. A test result outside the detection limit for the test method will be reported as ND.
ND = None Detected
ppm = parts per million by volume, ppb = parts per billion by volume, 1 ppm = 1,000 ppb
