Iodide (IFV)

According to Decree 280-2024 published on February 28, 2024, in the Gazette officielle du Québec, the amendment to the Appendix 1 of the Regulation respecting occupational health and safety (RSST, RLRQ, c. S-2.1, r. 13) will come into force on March 14, 2024. These regulatory changes have not yet been incorporated into the current Substance Data Sheets of the Sampling Guide for Air Contaminants in the Workplace. An update is currently underway and will be available as soon as possible. Consequently, the information contained in the data sheets of substances modified or added in Decree 280-2024 is partially inaccurate or incomplete. Please consult our infoLABO (in French only) for more details. Please contact our client service: [email protected] for further information.

Analysis:

Iodine

Recommended method by the IRSST:

Method: NIOSH - 6005

Sampling protocol

Sampling device: Alkali-treated charcoal tube, 100 mg/50 mg
Parameters:
Flow rate: 1 L/min
TWA sampling volume: 225 L
STEL sampling volume: -
Remarks: The recommanded method is not suitable for Iodine aerosol phase determination. For more information, please contact the IRSST. This substance is not analyzed by our laboratories. It might be possible that the analysis be performed by another laboratory. Please contact the IRSST before sampling.

Analytical protocol

Principle: Ion chromatography with conductivity detection (IC-CD)
Remarks: NIOSH 6005 method is for iodine ion analysis. All iodine ion generating compounds are thus detected, but not all have been studied for collection on a treated charcoal tube.
