TBM and THT are the most commonly used odorants to make odourless natural gas smell, so that people realize there is a gas leak. However, control of these odorants is necessary to maintain their effectiveness. Only last year, Sensorix offered its electrochemical (EC) gas sensors for mercaptan and THT detection – Sensorix TBM 50 and Sensorix THT 100 (read more here).
But due to various power to gas initiatives, more and more H2 will be added to natural gas. For this reason, a gas measurement device with high-performance gas sensors and no H2 interference is required. We are very pleased to confirm that the Sensorix TBM 50 is already suited for this application. To complete our respective range of sensors, we have developed the Sensorix THT 100 low H2, so we now offer a perfect solution for the detection of mercaptans and THT in natural gas with added H2.
Since last year the parameters of the Sensorix TBM 50 are still the same, namely:
- The gas sensor detects mercaptans with zero cross sensitivity towards H2, CO, H2S, THT;
- It has excellent repeatability (standard deviation of sensitivity = 0.5 % for 10 consecutive measurements at 10 mg/m³ TBM);
- The sensor shows excellent baseline stability from -10 to 40°C and in changing humidity (<0.1 mg/m³).
Moreover, its unbiased operation increases battery life in your portable instrument.
Our 3-electrode sensor, Sensorix THT 100 low H2 is suitable for power-to-gas applications due to its performance features:
- It has a very low H2 interference (THT signal only 1 mg/m3 in 20% Hydrogen);
- The sensor has no H2S cross interference;
- It requires 300 mV bias.
All sensors are available in various standard formats – 4S, 7S, Mini, Classic, Smart, as well as in customer specific mechanical adaptations.
