Highly specific gas chromatography and detector are combined with menu-driven operation, so that non-technical staff can obtain lab-comparable results under field conditions
The VaporLab from Microsensor Systems is described as setting new standards for hand-held workplace monitoring.
Highly specific gas chromatography and a sensitive solid state detector are combined with easy menu-driven operation, so that non-technical staff can routinely obtain consistent, laboratory-comparable results under field conditions.
Challenging measurements like that of benzene in an atmosphere already contaminated with gasoline are made routine by the instrument's excellent selectivity - even similar compounds like xylene, ethylbenzene and toluene give no measurable interference, and benzene is detectable to below 0.1ppm.
At the other end of the scale, a convenient Sniff mode provides easy real-time surveying of concentration hot spots without the need for blind sampling.
Other applications include ethylene oxide, vinyl chloride, 1,3-butadiene and acrylonitrile. The instrument has a built-in sampling pump and does not require a carrier gas supply or use replaceable absorption tubes - the saving on consumables alone will pay for the instrument in a year of normal use.
A full eight-hour day's work can be stored in the VaporLab and subsequently downloaded via wireless transfer to PC or Palm Pilot, so that no separate data logging is normally required.
Results are fully date/time stamped for easy auditing. The VaporLab is intrinsically safe to Atex standards and has a rugged impact-resistant case, so is ideal for use in the real world of refineries or chemical plants.
A rechargeable battery pack give six hours continuous operation.
UK distributor for VaporLab is Quantitech.
