Applies to: Chemical and Gas HazMatID (FTIR) Tickets Solved: 0 Rank: 8
To decrease background noise, ensure the sample area is very clean. The sample area should always be cleaned with alcohol before trying to use the HazMatID. If the HazMatID still has a lot of noise in the background, interference could be the issue. The interference could be due to the HazMatID being too close to power lines, medical equipment and even some cell phones. If you suspect that the background noise is being caused by interference, move the instrument to an open location away from any potential sources of interference.
