Potential hazard associated with scraping preparative thin layer chromatography plates.
Scraping TLC plates in a hood leads to contamination of the hood, equipment, worker, and the environment. The magnitude of contamination is presented as a fraction of the chemical delivered, and the effects of plate thickness, dryness, and adsorbent material are examined. Frequent clean-up and decontamination are recommended.
