38 Gas Detection Rapid Changes in Biogas Analysis
Biogas analysis requirements are changing. Designed for future proofing in gas analysers helps users keep up. It means they can quickly and easily upgrade their newly purchased products with new features anywhere in the world, anytime with online downloads available from Geotech (UK).
Positive global customer feedback on the new Geotech range of biogas and landfill gas analysers launched in early 2012 prompts the second set of new developments. This Geotech rapid response on the GA5000 landfill gas analyser and the BIOGAS 5000 especially suits users in countries with changing operational and legislative conditions.
Commenting Geotech sales manager, Simon Sheridan, said, “At Geotech we are dedicated to listening to our users and our distributors in every country and responding with speed to supply gas analysis with the capability they specifically need. That is very evident from these new enhancements. Our continued developments, packaged up as a single download, ensure we are meeting the needs of widely varying applications.”
Landfill gas analyser users can now optionally analyse up to six gases with the GA5000. Analysis of methane (CH4), carbon dioxide (CO2) and oxygen (O2) is standard and the choice of options includes carbon monoxide (CO), hydrogen sulphide (H2S) and hydrogen (H2).
The new faster operational sequence offers greater efficiency and productivity through monitoring more wells and achieving more readings each day.
Users can choose to have users prompts on or off and or a very quick ‘simple gas’ reading option. Users can now have up thirty sample-point IDs on the display screen in easy-to-read grid view, up from five IDs before. That helps with increased speed for users while maintaining precision and accuracy in operation.
Specially developed for research/pilot plant studies, universities and research institutes, data logging enables continuous timed monitoring of mixed-gas output. Geotech has now added this to its 5000 range of portable landfill gas and biogas analysers and already offers this on its CO2 gas analysers for incubator verification and the nitrous oxide (N2O) medical gas analyser range.

Combustible Gas Detector Provides Rapid 3-Second Response To Dangerous Leaks
The advanced Model IR400 Point IR Combustible Gas Detector from General Monitors (USA) features an industry-leading three-second T90 response time to the presence of combustible hydrocarbon-based gases, which allows plant operators to respond quickly to gas leaks and avoid potential accidents.
With its fast three-second response time, the Model IR400 Infrared Gas Detector provides an added margin of safety in protecting people, equipment and plants from potentially explosive gas leaks. The Model IR400 features rapid fail-to-safe continuous gas/vapour monitoring within the lower explosive limit (LEL). It reliably alerts plant employees to gas leaks and warns them to shut down processes in affected areas.
The Model IR400 gas detector responds within three seconds to gas leaks even with a splash guard installed to protect it from rain and other environmental conditions. It is important to note that most industrial point IR gas detection applications require a splash guard. Process and plant engineers need to be sure when specifying a gas detector that its speed of response is the same with a splash guard. In many cases, the addition of a splash guard slows the speed of response considerably.
The low maintenance Model IR400 gas detector monitors hydrocarbon-based gases including methane, propane, ethane, ethylene, butane, hexane, pentane and benzene. It features a self- diagnostic design to prevent false alarms and process shutdowns. It monitors conditions such as supply voltage and optical path integrity. The IR400 also features heated optics to eliminate condensation, and a dirty optics indicator helps discriminate between true alarms and maintenance needs.
The user-friendly Model IR400 uses only 4.8 W of power. It is designed for operational efficiency and system problem-detection capability. Additionally, the detector requires no routine calibration, a feature that reduces demand for field technician maintenance time.
The IR400 operates by measuring the absorption of infrared radiation passing through a volume of gas using a dual beam, single detector method. The IR detector measures the intensity of two specific wavelengths, one at an absorption wavelength and another outside of the absorption wavelength. The gas concentration is determined by comparing these two intensities.
The IR400 Detector can be configured for analogue output, Modbus, and HART. The IR400 provides a two-wire RS-485 addressable communication link, which supports the Modbus protocol, and is used to monitor status and settings in order to simplify installation and maintenance. Warning and alarm and maintenance events are available via Modbus or HART, as well as diagnostics and correction action capabilities. Its electronics are contained within a rugged, explosion-proof housing. The IR400 has FM, CSA, ATEX, IECEx, and BV approvals, the CE Marking, and is suitable for use in SIL 3 systems.

Industrial Gas Sensor Division Relocates Following Acquisition
Newly-formed SGX Sensortech Limited (UK) has cemented its recent multi-million pound acquisition of the instrumentation solutions business from e2v Technologies PLC with a move to new premises for one of its UK divisions.
The Industrial Gas Sensors division of SGX, the leading designer and manufacturer of gas sensors and x-ray detectors, has relocated from the site it occupied on Waterhouse Lane in Chelmsford for the last 50 years.
The move has seen the entire team transfer to a (8,500 sq ft) factory specifically modified to cater for sensor production on Hanbury Road in Chelmsford.
Tony Trocian, International Sales Manager for SGX Sensortech (IS), said: “We are delighted to officially unveil the relocation to our new, fit-for-purpose site, which marks a key milestone for us following the acquisition earlier this year.
“We are looking forward to starting the New Year in our new premises and further building on our success and strong heritage of innovation in the design and development of sensors by continuing to provide products of the highest quality and performance.
“The acquisition has positioned us as a market leader of innovative sensor and detector devices that offer unrivalled performance. The relocation is a vote of confidence for our capabilities and is just the start, with exciting plans for new sensors in the pipeline for next year.”
