PDF-Humans respirate Volatile Organic Compounds VOCs as well

D2 as CO 2 The BAPI sensor is able to measure these VOCs and indicate when a space is occupied just as well as a CO 2 The advantage of the VOC sensor is that it measures air contaminants from othe. Using PDB samplers can result in significant cost savings at sites where VOCs are the constituents of concern and particularly where longterm monitoring of groundwater is required PDB sampling can also provide inexpensive and precise vertical contam  Q0RWRURLOLVDVPHOO\VHHSDUWVZRUNVPRRWKO\(YHU\WKUHHPRQWKVRUVRWKHWDNHQRXWRIWKHFDUDQGIUHVKRLOLVSXWLQ8VHGPR - Volatile Organic Compounds (VOCs) Q&KHP $VDJDVWK Lecture 15.
