Continuous readings

PMU quality control specialist Jamie Hoyle said: "In the past, the hospital employed contractors to check levels of anaesthetic gases, but this only provided a limited amount of information; staff were fitted with sorbent tubes, so the results merely provided an average concentration for one day, for each of the target compounds.

"In contrast, the portable FTIR analyser can be configured to provide continuous readings for up to 25 compounds, so that we can either view live readings or leave the analyser to take measurements in a specific location. We are able to fully evaluate every room, identifying hotspots and locating any processes that result in higher concentrations, even if these levels are transitory."
