If other species (Different Gas Components) of gas present in the sample do not absorb any of the light wavelengths…
A very clever way to achieve selectivity with a non-dispersive optical analyzer is to replace the thermopiles with a detector…
Some analyzers measure the composition of a process stream by directly immersing the sensing element in that stream. This is…
One way to improve on the single-beam analyzer design is to split the light beam into two equal halves, then…
Non-dispersive analyzers employ the principle of spectrographic absorption to measure how much of a particular substance exists within a sample.…
Non-dispersive analysis, while newer in discovery than dispersive analysis (Isaac Newton’s 17th century prism), has actually seen far earlier application…
The dispersion of visible light into its constituent colors goes all the way back to the 17th century with Isaac…
Light is known to interact with matter in very specific ways, which may be exploited as a means of measuring…
Improving Chromatograph Analysis Time with Multi Column Gas Chromatograph The “Achilles heel” of chromatography is the extraordinary length of time required…
Arguably, the component most critical to measurement accuracy in a gas chromatograph is the sample valve. Its purpose is to…
