Servomex SERVOTOUGH SpectraScan Tunable Filter I.R Analyser

The SERVOTOUGH SpectraScan Tunable Filter I.R. analyser is an infrared absorption based on-line monitoring system, configured for measurement of light hydrocarbons (alkanes, alkenes and alkynes). The tunable filter allows spectral scanning which enables interference compensation. A real-time optical analyser capable of accurately separating the hydrocarbon components; which previously could only be performed by gas chromatograph (GC) analysers.

Using a unique wavelength-sweeping tunable filter spectrometer, fast update rates down to sub-second intervals are performed for the full C1 through C5 analysis. Sampling is a flow-through type, suitable for a continuous, on-line, unattended operation. The analyser does not require carrier gas, fuel gases, or on-site calibration gases.

The SERVOTOUGH SpectraScan utilizes a Precisive OXS-3100 optical bench which is used extensively in the field, and is available as a stand-alone analyser in two hardware configurations. Standard data interface includes a MODBUS TCP/IP. An ATEX, CSA hazardous rated instrument is available.
