On this page you will find a range of technical documents and information relating to the Spectronus available for viewing and download.
March 2020
- SpectronusTM Windows 10 Update
- Guides the customer through the upgrade of their Spectronus FTIR instrument
November 2018
- Spectronus Calibration
- Describes the calculations required to calibrate raw measurements from the analyser to a reference calibration scale. The calculations include dependence on isotopic fractionation in CO2.
- The Spectronus Measure Task
- Related to the metal cell description, the measure task implements the optimum cell exchange, filling and operating conditions in a generic task which can be adapted by the user to their own requirements.

August 2018
- Removal of Water Vapour and CO2 from Background Spectra
- This note describes the how water and CO2 features are removed from the background spectrum to improve accuracy.
- Spectronus FTIR Trace Gas Analyser – N2 Purge Requirements and Correction for CO in N2
- Describes how to minimise N2 purge gas usage and to correct for residual CO inevitably contained in the purge gas.
- Download extra files here – N2 prm files, Standard prm files, Measure demo
- Describes how to minimise N2 purge gas usage and to correct for residual CO inevitably contained in the purge gas.
- Spectronus Technical Note – Metal Sample Cell
- Describes the metal cell improvements over the original glass cell, and compares methods to optimise the exchange of samples in the cell for gas usage and/or time.
- Using a Forepump to Boost Cell Measurement Pressure
- Describes the advantages and implementation of a forepump in the sampling system upstream of the Spectronus to improve reliability and precision.
