Volatile organic acids tend to have a rather unpleasant smell and very low odour threshold values. To obtain a limit of detection which is low enough to detect these organic acids, a new analytical method was developed.
With the VOC Screening a lot of volatile organic acids are detected. However, the quantification is problematic due to the interaction of the organic acids with the used column for separation. In order to (semi)-quantify these acids, the focus of the Organic Acid Screening is moved towards the acids alone by using a more suited column. With the correct sorbent to trap the organic acids, OLFASCAN can measure organic acids from C1 to C6. Five Organic acids are calibrated in order to quantify the detected acids.
