EVM PID: Will Quest Technologies consider PPB resolution in future for Microbials (mold) for IAQ?

We are currently evaluating PID sensors with resolutions in the PPB range. At this time the EVM PID sensor only supports a PPM resolution sensor. For the question regarding measuring MOLD, this is not detected with the PID sensor. Instead, at high enough concentration, it may appear in the particulate mass concentration (depending on particle sizes of 0.1 to 10 um).
