LCS Laboratory supports occupational exposure assessments for 1,4‑Benzoquinone through validated air sampling methods and analytical procedures consistent with Canadian regulatory requirements. We supply calibrated sampling pumps, XAD‑2 adsorbent tubes, and full laboratory analysis.
Technical Overview
Quinone is a solid at room temperature but has a high saturated vapour pressure—approximately 100 ppm—which exceeds typical occupational exposure limits. Reliable sampling is therefore essential for accurate exposure characterization.
Sampling Methodology
- Reference method: NIOSH S181
- Sampling media: XAD‑2 adsorbent tubes
- Sampling phase: Vapour
- Recommended flow rate: 0.05–0.2 L/min
- Typical sample volume: ~24 L
- Analytical sensitivity: Detection limit of 1 µg/sample or better
These parameters support accurate quantification at concentrations relevant to occupational exposure limits.
Why Quinone Monitoring Is Important
Quinone is used in chemical manufacturing, polymer production, dye synthesis, and related industrial processes. Its vapour can cause respiratory irritation, skin sensitization, and other adverse effects. Routine monitoring helps:
- Verify compliance with Canadian occupational exposure limits
- Document exposure conditions for risk assessments
- Support engineering control evaluations and IH program requirements
