Air Monitoring
Performance Testing VOC
Audit Sample for Air Toxics
By Irene DeGraff, Product Marketing Manager
• Demonstrate your lab’s competence and compare anonymously to competitors.
• Improve your quality program.
• Applicable to US EPA, ASTM, and DIN EN ISO methods.
Restek is pleased to be a source of Performance Testing/VOC Audit Samples for
the Spectra Gases testing program. This is an on-going testing program in which
laboratories, or other users of VOC gas standards, are able to evaluate their own
capabilities and compare their performance with that of other air toxic labs. US
EPA methods TO-14A, TO-15, and TO-17 are used to determine volatile organic
compounds in ambient air. Without an air analysis accreditation program available, a
performance testing program by Spectra Gases provides an invaluable tool allowing labs to
demonstrate their competence with these methods.
As a participant in the program, you will receive a disposable cylinder directly from Spectra Gases
containing multiple unknown VOC components at varying concentrations that are to be identi-
fied, quantified, and reported via the Spectra Gases PT Audit Program form. The results will
then be published and distributed for peer review. The report provided to participants includes
a program methodology overview, compound list with actual concentration, and individual
and summary results for each compound (Figure 1). To ensure confidentiality, all participating
laboratories will be anonymous and only the individual laboratory will know their own results.
The audit sample will be shipped to all labs during the same period, once a year during the
fourth quarter. Analytical results need to be returned to Spectra Gases by January 30 to be included
in this statistical report.
