Summary
An optical spectrometer is a laboratory instrument used to analyse a gas sample to determine its composition.
How it Works
An optical spectrometer (spectrophotometer, spectrograph, or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials and chemicals.
By measuring the amount of light absorbed or reflected by a sample of an unknown substance it is possible to determine what it is made of and how much of each of its constituent materials it contains.

Optical Spectrometers are not widely used in the Oil and Gas Industry.
No case study available at this time.
On-line analytical methods involve extracting a sample from a flare system via an automatic sampling system and analysing it continuously with a field installed analyser system.
