Air Monitoring

BTEX, phenol, cresols and formaldehyde measurement in ambient air 

Jul 09 2018

The measurement of Volatile Organic Compounds (VOCs) in ambient air is a critical issue to ensure people safety near Industries area. Due to regulations, it is requested to control the level of VOCs rejected in the atmosphere. European legislation EN 14662-3:2015 requires specific certified instrument to measure benzene in ambient air. In some countries, Environmental Protection Agencies are looking for the monitoring of other pollutants such as phenol or formaldehyde near industrial areas. 

Chromatotec® has developed an all-in-one solution to continuously monitor VOCs (including Benzene, Toluene, Ethylbenzene and Xylenes), phenol, cresols and formaldehyde at low concentration. This autonomous solution is composed of an airmoVOC C6-C12 which is Mcerts certified following the EN14662-3:2015 and an airmoHCHO dedicated to the measurement of Formaldehyde. The solution includes as well the gas generators as the pumps needed for the sampling step. This complete package only requires a power supply to operate. An internal calibration system is used and decrease the need of external certified cylinders which are quite heavy to use and to handle. 

Specific communication protocols are available with the instrument (e.g. Modbus, JBUS, …) and allows to communicate with a Data Communication System (DCS). It is also possible using a datalogger to start some analysis remotely. Additionally, if the instrument is connected to Internet (e.g. using 3G modem), a specific software such as UltraVNC allows the user to have a complete access to all the functionalities of the instrument remotely. It becomes then very easy to check the instrument operating conditions. Moreover, all the parameters of the gas generators are available on the instrument’s computer offering to the operator an overview of the complete system status.
