The VP100 Continuous Flow Vapour System performs hydride and mercury vapour measurements with significant sensitivity improvement over normal flame techniques. An air/acetylene flame or an electrically heated cell is used for atomization, avoiding the need to use hydrogen as the fuel gas. The VP100 unit incorporates the reagent reservoirs, a variable speed 4 channel peristaltic pump, control electronics and Gas Liquid separator. A integrated Mass Flow Controller allows the carrier gas flow to be controlled and monitored through the system software, and the continuous flow principle eliminates the need to clean the reaction vessel after each sample. The VP100 operates automatically under Data Station control and can provide full autosampling operation with a suitable autosampler. When used with the EC90 Electrically Heated Atomization Cell, unattended operation is possible.
