Abstract:
VOC analysis is currently performed using gas chromatography as a measuring tool. The most common detectors are the Flame Ionization (FID) and the Mass Spectrometric (MSD) detectors. Both detectors require calibration using analytical standard solutions at known concentration of each detected compounds. For complex samples preparing these standard solutions, calibrating the chromatographic system and processing the samples chromatograms can be time consuming and costly. Carbon centric detectors directly measure the mass of carbon corresponding to each chromatographic peak. Knowing the chemical compound nature of the eluting compounds, possibly by using a spectroscopic detector, enables a direct unbiased estimation of the mass of compound eluting of the column. In addition to delivering accurate VOC levels, such detectors also simplify both the calibration of the system and the data reduction step of the analysis. In this talk we will compare several “carbon centric” detectors in terms of performance, easiness of use and cost.
