Benzene / Toluene / Xylene (BTX) analyzer

The GC955, designed and manufactured by Synspec Netherlands, is a gas chromatograph with a built-in pre-concentration system. Hydrocarbons are pre-concentrated on Tenax GR, desorbed thermally and separated on an EPA624 equivalent column, to reach optimal separation from interfering hydrocarbons. Analysis is done by a photo ionization detector. This ensures a high specific sensitivity for benzene and other aromatic hydrocarbons.

The standard analyser set-up includes toluene, ethylbenzene and o-, m-, p-xylene are as standard included in the analyser set-up. With different settings and suitable calibration gas it is possible to measure up to 40 components, like octane, chloroethenes, trimethylbenzenes etc. in one 30 minute run.

The user will have to buy the suitable calibration gas and needs training to set the system for extra parameters and calibrate for them

A user-friendly software is provided to store all the chromatograms on the hard disk and data can be interpreted easily with this

intuitive software. Data can also be transferred by network and modem connection. Besides this, analogue and digital output options are available to communicate with other data logging systems using several data protocols.
