TIC Detection Tubes
High Priority Industrial Gases & Vapours
High Priority Industrial Gases & Vapours
TIC detection tubes cover high‑priority industrial gases and vapours. The indication layer chemistry (e.g., 4‑(p‑nitrobenzyl)pyridine with N‑phenylbenzylamine for phosgene) produces a distinct colour change after the prescribed number of pump strokes; users compare the layer to the printed reference scale to estimate concentration.
Why teams choose TIC detection tubes
- Broad pollutant coverage for emergency services and industrial HAZMAT.
- Simple, low‑burden workflows suited to gloved operation.
- Pump‑agnostic: works with CHP‑5 and other common aspirators.
How it works
Break the reagent ampoule (if present), draw the labelled sample volume (strokes), then match colour to the etalon; many tubes include approximate concentration bands on the label.
