We left yesterday evening with the analyzer which was working, calibrated in xylene, the 4-20 mA signal operational, the customer is satisfied and pointed out to us that he was pleasantly surprised by the support you gave us in live.

The Signal [FID] instruments are rugged, accurate and reliable, and we are obviously delighted that they have provided so many years of reliable service. To maintain this high level of performance, the instruments’ linearity is checked annually and Signal services the instruments twice a year

Our customer purchased Signal Group’s latest fixed, heated FID, the S4 SOLAR, and we needed a little help with setup and commissioning because the customer wanted to calibrate his device with a special gas rather than propane. We therefore contacted Signal and they were able to log into the analyser remotely and quickly changed the analyser settings. Following this amendment, the analyser was operational in no time. As a result, the customer was delighted and said that Signal’s remote diagnostic capability was a very pleasant surprise!

“The Gas Divider has worked very well; helping us to assure the accuracy of our measurements, whilst reducing the number of calibration gas bottles required. This reliability is further assured by regular calibration checks that are performed by Signal Group.

FID: the VOC emissions monitoring reference method – for over 50 years!

The Flame Ionisation Detection (FID) method was first developed in the 1950s for the laboratory analysis of organic chemicals. Later, when environmental regulations began to limit the emissions of volatile organic chemicals (VOCs) in the 1970’s and 1980’s, the FID method was adapted for emissions monitoring. Signal Group was one
