Histogram of simulations of 10-ppbv DIMP detection in contaminated air overlaid with the histogram from simulated measurements of 10-ppbv DIMP in clean, dry air.
Simulated sensor response to 0-ppb DIMP in contaminated air. The PFP for an alarm threshold of 1.5 ppb is the area divided by the sum of areas and .
Plot of PFP vs detection threshold for detecting DIMP from simulated measurements of heavily contaminated air with , 4% , and 550-ppm (a total of 45 interferents) and using 87 laser lines from a laser. A PFP of is achieved for a detection threshold of 4.15 ppb.
Simulated sensor response to 2-ppb DIMP in contaminated air. The PFN obtained by analyzing the number of sensor readings that are below a particular alarm threshold even though DIMP is present at higher concentrations.
