  Online Monitoring of Methane in Ethylene Impurity Control

  Wednesday, December 19, 2018 | Airat Amerov & Michael Gaura

  Technologies Products Applications

  Monitoring very low-level concentrations of methane requires precise and reliable analytical solutions. Tunable diode laser absorption spectroscopy (TDLAS) is a real time analysis technology that combines a non-contact optical technique with long term stability, high specificity, and considerable sensitivity.
