Context & Challenges
Volatile organic compounds (VOC) can be dissolved in water. Sometimes water is polluted and to study contamination of VOC in finished drinking water, VOC must be measured.
Chromatotec® has developed a specific system for the measurement of VOC in water: a Purge & Trap system, the airmoPURGE. The analyzer is coupled with a degasing system allowing the extraction of dissolved gases.
The complete system is based on:
- 502.2 method from US EPA – “Volatile organic compounds in water by purge and trap capillary column gas chromatography with photoionization and electrolytic conductivity detectors in series – Revision 2.1”.
- 524.2 method from US EPA – “Measurement of purgeable organic compounds in water by capillary column gas chromatography/mass spectrometry – Revision 4.0”.
