Formaldehyde analyzer GA­SA­NA­LY­SER

gaslaboratoryconcentration

The precise and reliable analysis of the formaldehyde emission from wood based panels - in compliance with the standard EN ISO 12460-3 - is possible with the gas analysis unit GreCon GASANALYSER. The GASANALYSER is characterised by its compact design, the low energy consumption and the intuitive and safe operation via a large colour touch screen. Benefits at a glance Analysis of the formaldehyde emission in only few hours Accepted by CARB No use of the health-damaging toluol Reliable results also in case of very low emitting samples Intuitive operation via a 10“ colour touch screen No waiting times thanks to the programmable heating of the measuring chambers Silent in operation Data export (e.g. history) by USB interface Flexible valve configuration Design of the system The two measuring chambers made of polished stainless steel are controlled separately and can be used independently. An airflow of 60 l/h with a temperature of 60 °C channels the formaldehyde emitted from the test specimen out of the measuring chamber into gas wash bottles. Before introducing the air into the measuring chambers, it is cleaned with silica gel and filtered to achieve a clean air flow. According to standard the air flow is fed to four pairs of wash bottles for a period of four hours, i.e. formaldehyde containing air is blown through each pair of wash bottles for one hour. After the forth hour, the air flow is stopped automatically. The sequence to open and close the valves is regulated by the PLC. As measuring temperature and valve configuration can be adapted, a flexible reaction on future changes of the standard is possible.
