Abstract

Uncertainty evaluation was performed for the measurement of Volatile Organic Compounds(VOC) in indoorair. The analytical procedure and result were validated by evaluating every uncertainty source related to themeasurement method. An easy approach for uncertainty evaluation for indoor VOC measurement was testedusing relative standard uncertainty method which is simple in the evaluation of a measurement uncertainty incase of indoor VOC measurement. The measurement uncertainties of toluene, ethylbenzene, m+p-xylene,styrene and o-xylene in indoor air are obtained as less than or close to 10%, and those results werevalidated by using Gum-workbench uncertainty evaluation program. Based on the evaluation, uncertaintieswere found to come largely from two major sources; uncertainty related to the concentration of standardTenax tube which was used for calibration in measurement, and the to air sampling process. This studycould be used as a good example in evaluating uncertainties in the measurement of indoor-air VOC atbuildings including a newly-built apartment.
