APPARATUS FOR MEASURING CONCENTRATION OF TOTAL VOLATILE ORGANIC COMPOUNDS AND METHOD FOR MEASURING CONCENTRATION OF TOTAL VOLATILE ORGANIC COMPOUNDS USING THE SAME

摘要

The present invention relates to an apparatus to measure concentration of a volatile organic compound and a method of measuring the concentration of a volatile organic compound using the same and, more specifically, relates to an apparatus to measure concentration of a volatile organic compound capable of having a small size and capable of measuring highly sensitive total volatile organic compounds (TVOC) in parts per billion (ppb) concentration level, and a method of measuring the concentration of a volatile organic compound using the same. To achieve this, the apparatus to measure the concentration of the volatile organic compound comprises: a first carbon dioxide measuring device measuring concentration of carbon dioxide of input gas; a second carbon dioxide measuring device measuring the concentration of carbon dioxide of discharged gas; and a volatile organic compound (VOC) decomposer arranged between the first and second carbon dioxide measuring devices.
