For surface wipe sampling, contact Laboratory Customer Service.
The analytical results are expressed as total water-insoluble chromium VI.
Surface tests for chromates can be carried out, and the required equipment (kit
#2625) is available at the IRSST. See communiqué 2008-06 on our Web site.
Analysis time of 8 days for welding fumes and 10 days for the other processes
following the sampling date. Ship all samples by rapid courier within a period not
exceeding 24 hours after sampling.
Any substance that produces a response on the detector at 540 nm and that has
a retention time similar to Cr VI is a potential interference.

Refer to the user's guide accompanying the instrument.
Styrene is quantified in the field with a direct-reading instrument (DRI). The
minimum reported value is of 0.5 mg/m³ (0.12 ppm). The reference method
corresponds to calibration of the DRI.

For the monitors, the flow must be considered as being a sampling rate.
According to the data from 3M, the precision (CVsampling) of the sampling rate is
3.0%. Refer to the 3M passive monitor guide on the IRSST's Web site.

The analysis can be done by gas chromatography coupled with mass
spectrometry (GC-MS, IRSST method #369); in this case the analytical
uncertainty (CVa) is 3.0%.
