• Compounds Analyzed: Benzene, Toluene, Ethylbenzene, Xylenes, 1-3 Butadiene in air
• Measuring Technique: PID Gas chromatograph
• Measurement Range: up to 300 ppb
• Lowest detection level for benzene 0.1 μg/m3 (0.03 ppb)

General Aspects

The Syntech Spectras GC955 series 600 BTX analyzer is built for the measurement of benzene, toluene and xylene isomers in ambient air.
In the European regulations measurement of benzene in ambient air is now obligatory. The concentration of benzene varies from under 1 to above 100 micrograms per m3.
For authorities wanting to measure benzene our instrument is the ideal choice: our instruments are not only designed for the analyst working in the laboratory, but especially for the technician working in a field station or at a control panel. Specialized chemical knowledge is not necessary.
 

In the GC a standard industrial PC with Windows is used. This means that the whole PC structure is available to handle also the results of measurements: data are interpreted and saved on the internal hard disk. Data can also be transferred by network and modem connection. Besides this, analog and digital output options are available to communicate with other data logging systems using several data protocols.

Simple operation, good reliability and low maintenance cost are important to us. With a network of distributors in and outside of Europe you can be sure that your instrument comes complete with an individualised training and that support is available to help if you do encounter problems. The new Syntech Spectras GC955 works on only one gas, nitrogen, using a very small quantity.
