Endress+Hauser is now the exclusive Canadian provider of SpectraSensors gas analyzing technology.

April 9, 2019 – Endress+Hauser is now the exclusive sales and service source for SpectraSensors in Canada, whose gas analyzing technology is used to measure contaminant levels in natural gas and gas processing operations, refineries and chemical plants.

Endress+Hauser Canada will assist customers to choose analyzers with the proper sensitivity level to generate consistently accurate readings of analyte, such as moisture (H2O), hydrogen sulphide (H2S), carbon dioxide (CO2), oxygen (O2), acetylene (C2H2), ammonia (NH3) and gas composition.

Customers will have access to the factory-trained local resources of Endress+Hauser, training in Process Training Units, bilingual telephone support and on-site services (commissioning, maintenance and repair). Endress+Hauser can help customers incorporate the data stream from their analyzers into their IT infrastructure, including IIoT systems.

SpectraSensors analyzers employ three main optical technologies – TDLAS (tunable diode laser absorption spectroscopy), Quench Fluorescence and Raman Spectroscopy – to measure a number of gas concentrations in hydrocarbon gas applications. TDLAS was introduced to the natural gas industry by SpectraSensors more than a decade ago as an analytical technology for measuring contaminants, with a fast response rate and durability.


The analysis component of these three optical technologies – a beam of light – isn’t in direct contact with the gas, and therefore doesn’t degrade. The rugged nature of these optical gas analyzers has allowed them to be used in natural gas pipelines with very little maintenance, no cross-interference, and with no detrimental effects from glycol, methanol, amine, H2S and more in the gas stream. They require no field recalibration.

In Canada, most of the demand for gas analyzers is on an upstream gathering network at the entry point to an intermediate gas processing plant, then on the other side of the plant to measure the effectiveness of contaminant removal. The gas is analyzed again when it reaches the custody point of a mainline gas pipeline system to ensure it meets the regulatory standard for onward transmission.
