Note : The SapphIRe-SL contains those compounds with and “SL” in the library column. The
SapphIRe-XL contains all compounds in this list.
Accuracy is defined as +/- the average value displayed from five times the detection limit to the
full scale reading (e.g.. Acetaldehyde from 4.0 to 400 ppm: accuracy is +/- 10% of reading.
Detection limit is the point at which the analyzer will consistently and repeatably detect the
presence of the subject gas.
(a) Carbon dioxide (absolute) refers to the measurement of CO
2
where the SapphIRe analyzer
has been purged with CO
2
free air such as nitrogen. Since CO
2
is present in the air at levels
of approximately 350 ppm and since the zero gas filter cannot scrub the CO
2
, the only way to
generate a true level of CO
2
is to flush or zero the analyzer with CO
2
free air. The factory
calibration for CO
2
was zeroed with nitrogen. Likewise, when using the CO
2
(absolute)
calibration, the analyzer must be zeroed with CO
2
free air.
(b) Carbon dioxide (differential) refers to a measurement of CO
2
when the SapphIRe analyzer is
zeroed in a level of normal ambient air (350 ppm of CO
2
). When this calibration is used, a
background level of CO
2
must be added at the zero area to the analyzer’s display value.
(c) 0 to 1 ppm (

10%); 1 to 4 ppm (

20%)
