EPA TO-17 Volatile Organic Compounds on Sorbent Tubes

EPA TO-17 is a method for volatile organic compounds (VOC) collected on sorbent tubes.   Depending on the compounds of interest, different sorbent tubes can be used (see list below).  TO-17 tubes are analyzed on the same concentrator at the TO-15 and while the method does not specify any QC criteria, it suggests that the TO-15 criteria can be used.

Word about Method Detection Limits (MDL)

Defining Detection Limits

Detection Limits are used to specify the lowest concentration of a compound that can be measured reliably by the analytical method.  There are several definitions for the detection limits used by laboratories so it is important to understand the differences, so that the objectives of your project are met.  On this web site, the term detection limit is used as a general term to collectively describe the more specific terms such as the Method Detection Limit (MDL), Lower Quantitation Limit (LQL), Reporting Limit (RL), and Method Reporting Limit (MRL), and Practical Quantitation Limit (PQL).
