Long-Path Flow Cell for Gases

Guided Wave offers this flow cell specifically designed for long optical paths up to 1 meter.

The NIR spectrum is rich with information to quantify gas concentrations and distinguish gases in a mixture. Some of our applications include:

0-2% ethylene in ethylene dichloride
0-2% propylene in propane, carbon dioxide and air

UV/VIS applications include:

Chlorine and bromine gases

Here is an example of gases in the NIR. The differences shown below provide a reasonable means to quantify mixtures.
