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 GA 6000. The GA 6000 is characterised by its compact design, the low energy consumption and the intuitive and safe operation via a large colour touch screen.
- 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
- An upgrade of GA 5000 to GA 6000 is generally possible
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. The lines of the test air as well as the valve blocks are heated to avoid any condensation and resulting measuring errors. An automatic leak test issues a warning if a leakage occurs.
The relevant test parameters - as required in EN ISO 12460-3 - can be exported via a USB interface. Furthermore, the sample identification as well as date and time of the test are saved in the history.
With a GA 6000 you will have the possibility to participate in a ring robin test for the gas analysis in compliance with EN ISO 12460-3 free-of-charge for two years.
In a ring robin test, matched samples are tested with the same method by different laboratories. The results of the participating laboratories are processed graphically and statistically. An - anonymised - comparison and consequently a statement on the measuring quality of the company's own laboratory is possible. Ring robin tests are a central instrument for the introduction of a new measuring method and for the continuous quality assurance.
The ring robin tests are carried out by Steve Young Associates (SYA) and are completely anonymised. The request for samples, the entry of results and the issue of reports all take place online via a password protected access. After two years, it is possible to continue the ring robin tests against payment of a fee.
The software of the GA 6000 is implemented on a PLC with integrated touch panel. Access to the user interface is possible via this touch panel.
The system is operated by the user interface. Here, the user may e.g. switch on the heating, start a test or - if stored - select a special valve configuration. Furthermore, the status of the system is displayed, e.g. the current values of the test parameters temperature, the air flow and the test progress. If required according to EN ISO 12460-3, the parameters of temperature, air flow and pressure are saved as average values for each test hour and each test. Date and time are added automatically. Moreover, the user may enter an individual identification for each test, e.g. a production number. The details of the last ten tests can be seen in the history and exported via USB interface.
