18 Gas Detection Photo Ionisation Detector – Plus (PID-Plus)
Alphasense (UK), an independent gas sensor technology company, has been working with Owlstone to apply their Advection Diffusion Spectrometry (ADS) technology for chemical detection, on a new development based on the Alphasense PID modules giving enhanced selectivity through the use of the Ion Mobility Spectroscopy (IMS) - ADS technology.
Utilising existing PID technology and linked to a sensor module that has been produced featuring a chip, fan for gas sampling, the micro-controller with associated electronics uses UV as the preferred ionisation source. The sensor module/chip, has embedded firmware, is mounted to a rigid circuit board as part of the newly developed Owlstone IMS-ADS module.
Gas flow through the chip must be regulated and at least two signals will be output (peak height and peak width), a third signal (kurtosis) is possible but will require additional work to the sub-module. Signal outputs could be analogue, PWM or serial. End-users will have no need to see raw spectra, as all processing will be performed on-board.
Arthur W Burnley, Sales and Marketing Director for Alphasense, stated, “Successful development of this new sensor technology will open a range of exciting commercial opportunities for Alphasense. We are very happy to be working with Owlstone in what will prove to be a mutually rewarding partnership, and we are anticipating that this device will be available for sale in Q3 of 2011. Alphasense is a centre of excellence for gas sensor technology and the PID-Plus is just one of several new and exciting product introductions planned for 2011. Further developments from Alphasense include expansion of our existing NDIR, Catalytic and Electro-Chemical sensors (measuring as low as 10ppb) plus the addition of Mixed Metal Oxide sensors and more.”
Reader Reply Card No. 191 Confined Space Gas Detector
Scottish based Gas Measurement Instruments Ltd (GMI), a long established manufacturer of gas detection equipment, presents its Personal Surveyor (PS200 Series) product range. This state of the art multi-gas detector is sold internationally to the industrial safety, shipping and utility markets.
The PS200 is a small yet extremely robust, four gas detector that will detect 15 combinations of flammable, oxygen, hydrogen sulphide and carbon monoxide gases.
This instrument has been specially designed to be easy to use, yet incorporate modern pcb, sensor and battery technologies. Extra loud audible, bright visual and vibrating alarms are designed to keep workers safe when working in confined spaces.
This new portable detector can be bump tested and calibrated automatically ensuring worker safety, corporate compliance, instrument accuracy and record keeping. The bump test and calibration station is available in standalone, PC and networked versions.

Industrial Scientific (USA) is pleased to announce the availability of the Ventis™ LS multi-gas detector as part of the Accenture Life Safety Solution. Using Wi-Fi and location-based technologies to remotely monitor those working in potentially hazardous environments, this wireless solution helps keep people safer.
The Accenture Life Safety Solution leverages the expertise of Industrial Scientific, as well as their unique Gas Detection as a Service solution known as iNet®. It also incorporates the leading technologies and processes of Accenture, AeroScout and Cisco. The solution is designed to continuously monitor employees working in plant environments across oil & gas, chemicals, petrochemicals, metals, mining, forest products and utilities.
The Ventis LS has the ability to detect one to four
gases, including H2S, O2, LEL, CO, SO2 and NO2. In potentially hazardous conditions, the instrument alerts users through audible, visual and vibrating alarms. The instrument’s gas level information is then transmitted over Cisco’s Unified Wireless Network using the gas detector’s integrated Wi-Fi Tag from AeroScout. The gas detection information is then sent to a control room, where an operator can react to the data. Because of the gas detector’s wireless technology, the operator can quickly locate the employee in danger, and organise rescue operations. A separate alert would be sent to the control room if lack of motion is detected or if the individual activates the detector’s panic button.
The Accenture Life Safety Solution extends itself beyond the plant’s confines. Operators can go outside of the plant with the same functionality using a combination of Wi-Fi and cellular communications.
The solution was initially field tested at two units at Marathon Petroleum Corporation’s (NYSE: MPC) Robinson, Ill., refinery. After successful testing, it was later deployed through the remaining refinery units, tank farm and outside the refinery fence line to include remote workers.
“Our deployment of this pioneering solution follows extensive evaluation of its functionality and costs,” said Don McCord, operations manager, Illinois Refining Division, MPC. “The tested solution gives our workers a greater sense of confidence that their safety is being monitored in ways that have never been possible before in our industry. In addition, its proven cost effectiveness has allowed us to deploy the solution across the entire refinery.”
