Rapid Analysis is Key to Successful Management of FOG
Hydrogen Monitoring Improves Syngas Efficiency
The efficiency of syngas production is greatly improved when hydrogen levels are monitored using H2scan technology that is able to measure continuously without interference from other gases.
Continuous hydrogen measurement provides an opportunity for real-time control of the production process; delivering a final product with the correct ratio. In the absence of hydrogen measurement, the end product ratio can only be an estimation.
Quantitech has supplied hydrogen-specific analysers to the UK market
for the last four years and syngas is a further example of the many applications in which hydrogen-specific gas measurements have delivered tremendous benefits.

New Portable FTIR Gas Analyser Available for Hire
The new Gasmet DX4040 portable FTIR multi-gas analyser is now available for hire from Quantitech Limited.
For each rental Quantitech’s Dr Hobson configures the instrument to meet the customer’s specific gas monitoring needs. He says: "The DX4040 has brought laboratory grade gas analysis into the field and the availability of a rental system means that even those with a limited budget or a short term requirement can have access to the best technology.”
The DX4040 is supplied with a PDA which enables the user to measure up to 25 (user defined) gases simultaneously. The FTIR sample spectrum is saved to the PDA with every measurement made; this allows post sampling analysis of additional compounds and identification of unknown gases.

In some parts of the UK, the majority of sewerage blockages occur due to a build up of Fats Oil and Grease (FOG) from food-related activities, domestic homes and industry. Quantitech Managing Director, Keith Golding, believes that successful management of the problem, through best practices and effective grease interception, can only be achieved when rapid analysis tools are employed.
The advantages of infrared analysis over the gravimetric method are simplicity and speed. Portable, relatively inexpensive fixed-filter infrared analysers, such as the Wilks InfraCal TOG/TPH Analyser are currently employed by regulators and water companies to quickly determine who their “FOG clog” offenders are.
Plant operators are able to take samples both before and after treatment in order to study the process under differing load conditions, so that system parameters can be changed quickly without having to wait for laboratory results. Most importantly, effluent containing fats, oil and grease above the regulatory limits can be diverted before a blockage is caused.

Analyser Helps Protect Safety of Compressed Air

“We’ve got an ‘APP’ for that!”
With the world’s leading technologies, Quantitech can deliver bespoke monitoring solutions to precisely meet your needs
Quantitech’s bespoke FTIR multiparameter gas analysers from Gasmet are confi gured with APPlications to meet the monitoring needs of each customer.
An advanced multiparameter gas analysis technology (FTIR) from Quantitech is being employed by Case Chemicals as part of its compressed air testing services for recreational, industrial and military applications. According to Case’s Sam Wray, “This technology provides much higher levels of confidence than traditional techniques, partly because it is highly accurate and also because FTIR can detect almost any gas or vapour.”
The FTIR analyser employed by Case Chemicals was supplied by Quantitech’s Dr Andrew Hobson who pre-configured the analyser (a Gasmet DX4030) to measure a wide range of parameters including CO,
CO2, hydrocarbons, NH3, HCl, HF, NO2, N2O, SO2 and a range of halocarbons such as Freon.
Sam Wray says, “In the past, some of our clients have used chemical stain tubes which can have an error of up to 30%, so whilst these are individually cheap, they are highly inaccurate in comparison with FTIR and only test for one gas.”
