Signal Group’s portable heated FID VOC analyser, the S4 SOLAR XPLORE, has made it to the finals of the Instrumentation Excellence Awards, and a team from Signal will be donning their red-carpet attire for a glittering award ceremony that will take place at the Grand Connaught Rooms in London on

REMOTE CONTROL SOFTWARE: optional software suite to allow fully automated test and relinearization of Signal series 4 analysers.

Intriguingly, the Signal Group stand will be staffed by gas analysis experts wearing T-shirts saying ‘Ask me about MCERTS!’ It’s too early to say more, but anyone interested in VOC emissions monitoring should head for Stand-L5…if only to try out the detachable tablets. With a heavy focus on technology development,

Researchers at the University of Sheffield are exploring new exhaust aftertreatment systems for heavy-duty engines capable of running on clean, zero-carbon fuels. This 4-year project is funded by an EPSRC grant and supported by the industrial partner Eminox. The project is led by Bill Nimmo, Professor of Energy Engineering and

The 821S has ten identical capillaries and a precision balance regulator. The span gas can be selected to flow through a number of those capillaries with the diluent flowing through the remainder, to produce a ratio. Many types of gas analyser are inherently non-linear due to the physical nature of the analysing technique. Photometric analysers (NDIR, NDUV, FTIR / spectrophotometers) need to be linearised before they leave the factory and then at regular intervals during service. Other more linear analysers will also need to be checked for linearity periodically whilst in service. This should be part of the QA/QC regime. Also known as a gas blender or gas mixer.

The Signal Group’s 821S Gas Divider enables the users of gas analysers to test the linearity of their instruments – simply, quickly and accurately. The 821S has ten identical capillaries and a precision balance regulator. The span gas can be selected to flow through a number of those capillaries with the diluent flowing through the remainder, to produce a ratio.
