Lab in a back-pack

Published: 5-Apr-2007


UK company Quantitech has launched what it claims is the world's first truly portable FTIR multicomponent workplace gas analyser.

In the past, field-use instruments for the detection of toxic gases have sacrificed analytical performance for the sake of usability, the company says, but its Gasmet Dx-4030 analyser provides both field-usability and high levels of analytical performance.

The DX-4030 employs FTIR (Fourier Transform InfraRed Spectroscopy) analysis, producing almost instantaneous readings for multiple compounds across a wide measurement range that extends to sub-ppm levels.

No sample preparation is needed; the sample gas is drawn into the analyser module by a pistol-type sample probe, which has a built-in pump and a particle filter. The whole system is battery operated with an operating time of several hours.

Data collection and display is facilitated by an easy-to-use PDA (Personal Digital Assistant) user interface with Calcmet-Lite software. The analyser module and the PDA communicate via wireless Bluetooth protocol and measurements for each compound are displayed at the touch of a button.

“We are very excited about the DX-4030; for the first time users will have a truly portable device that will enable them to measure almost any parameter real-time, without having to know in advance which gas or vapour to test for,” said Quantitech director Dominic Duggan.

“As a consequence, we foresee a great demand for this highly advanced technology in applications such as chemical spill response, industrial hygiene, contaminated land, leak detection and the measurement of anaesthetic gases in hospitals.”

In regulated manufacturing, monitoring environmental conditions and critical equipment is essential to protect product quality, yield, and patient safety. Facilities often use a Facility Monitoring System (FMS) to track factors like airborne particles, temperature, and humidity. Beyond regulatory compliance, FMS delivers real business value through reduced waste, improved yield, higher quality, and greater profitability
