Method for calibrating olfactometer output. Part 1. Acetic and propionic acids

Abstract

An analytical method for measuring acetic acid and propionic acid in air was developed and validated. This method entails collection of acetic acid and propionic acid on XAD-7 sorbent tubes connected to an olfactometer and extraction of the sorbent in a solution of methanol and formic acid. The acids are then determined by gas chromatography with flame ionization detection. This methodology was successfully implemented in calibration of olfactometer output.
