Gas Filter Correlation (GFC) Spectroscopy
Using filter cells to eliminate wavelengths associated with interfering gases is called positive filtering in the field of spectroscopy. You
Analyzers

NDIR Analyzer Filter Cells
If other species (Different Gas Components) of gas present in the sample do not absorb any of the light wavelengths
Luft detector Principle
A very clever way to achieve selectivity with a non-dispersive optical analyzer is to replace the thermopiles with a detector
Analyzer Sample Systems
Some analyzers measure the composition of a process stream by directly immersing the sensing element in that stream. This is
Dual-beam Non-dispersive Analyzer
One way to improve on the single-beam analyzer design is to split the light beam into two equal halves, then
Single-beam Non-dispersive Analyzer
Non-dispersive analyzers employ the principle of spectrographic absorption to measure how much of a particular substance exists within a sample.
Non-Dispersive Analyzers
Non-dispersive analysis, while newer in discovery than dispersive analysis (Isaac Newton’s 17th century prism), has actually seen far earlier application
Dispersive Spectroscopy
The dispersion of visible light into its constituent colors goes all the way back to the 17th century with Isaac
Absorption Type Optical Analyzer
Light is known to interact with matter in very specific ways, which may be exploited as a means of measuring
