Alpha 400, designed and manufactured by Synspec Netherlands, is a gas chromatograph based simple but precise benzene only analyzer.

Alpha 400 is a compact GC containing all the essential elements: preconcentration sampling unit, backflush valve, separation column in special small oven unit and detector. The detector is a PID.

The gas sample is concentrated in a TRAP. The sample is then desorbed and injected over the valve into a column and benzene passes on to the detector. The system is optimized for ambient benzene concentrations.

All higher boiling hydrocarbons will be BACKFLUSHED. This gives two advantages to the system: auto cleaning every cycle and that a very short cycle ( for benzene standard 10 minutes). The system is adapted to the specific hydrocarbon that must be monitored with regards to the essential parameters: column, flow, temperature and backflush setting. The OVEN is isothermal

Alpha’s software has got two levels of user’s interfaces: user’s level for an operator and a higher level for a technician allowing to adjust, calibrate and maintain the gc. Both interfaces communicate with a Server. GC data can be accessed locally or remotely by dedicated software for client and for technicians for all necessary functions: data transfer, including alarms, calibration start, program adjustment, communications with external equipment like stream selectors. the access can be local, by modem or via internet.
