Handling them is difficult and dangerous, yet these chemicals are vulnerable to the same sources of contamination and degradation as milder chemistries. Metara's Sentry HCM system, introduced last week, automates sampling and analysis of harsh chemistries. Their electrospray time of flight mass spectrometer achieves 200 ppt detection limits for common metal ions, with 40 minute turnaround time. The system, the company claims, allows real time monitoring of harsh chemistries, without the hazards inherent in manual sampling.
