Twin TDL analyser measuring HF and H2 for Lithium Ion battery safety testing

Our customer was looking for a unique combination of measurements to provide insight into the hazard potentials of fires that involved Lithium Ion batteries. Evolution of hydrogen could present a fire or explosion risk and they are right to be concerned over levels of HF due to its extreme toxity and reactivity.

After consultation with our esteemed principal Airoptic and deep discussion with the customer, the solution was to provide an extractive Tunable Diode Laser analyser, with twin lasers and a common gas cell, all wrapped up in a neat 19″ enclosure.

GasEyeTM Extractive is a laser spectrometer that uses single line molecular absorption spectroscopy. A semiconductor laser emits a beam of infrared light which passes through the process and impinges the detector on the receiver side. When the target gas is present the light intensity changes and this can be used to determine the concentration of the measured specimen. The wavelength of the radiation emitted by the laser is chosen to match the specific gas absorption wavelength. The laser continuously scans this single absorption line with a very high spectral resolution. The measurement is very selective due to narrow band nature of the laser light.

FPT has developed a solid 2-way relationship with Winkler, feeding back the market’s requirements, providing suggestions for product improvements, and also sharing successes – FPT will discuss your application in detail, help specify beneficial product variants, and also work with their other suppliers to provide a considered total solution.

In the world of low-concentration monitoring (ppb to ppm), emissions monitoring, and engine testing, it is vital to have reliable, continuous heating of sample lines and no cold spots where components can condense and escape measurement. Where poor heating, and bad connections with probes, analysers, or other lines risk invalidating expensive measurements, quite literally “cold spots cost”.  By choosing Winkler lines, connections, and other heating solutions, you can put your mind at rest that you have given the best chance to succeed with your measurements.

Let’s start with a focus on the Winkler “Quick-Lock” system….

Connection system “Quick-Lock”

For quick assembly of heated lines. Used at dynamometer and engine test beds for carriage of measuring gas into the analysing room safe and conforming to standards.

• Rugged structure made of high-quality materials. The system is designed for sustained operating temperatures of up to 200°C.
• Seamless (conforming to standards) heating without cold spots between the wall bushing and the heated line and the heated line coupling
