Flange-Mounted NIR Liquid Process Cell

Flange-Mounted NIR Liquid Process Cell


Liquid Transmission Cell for UV-Vis and NIR

Specac ProCell™ Vortex Process Cells are a range of flange-mounted liquid transmission cells for in-situ monitoring of process streams by UV/Vis and NIR optical spectroscopy over optical fiber. 

ProCell™ Vortex Process Cells are designed to be installed either directly on a process plant or in a short by-pass loop. To ensure ease of process integration, the cell can be configured from a wide range of ANSI and DIN flange sizes. The cell is easily trace-heated and insulated for use at elevated temperatures, and cleaning ports can be added to facilitate in-situ cleaning of the windows. A propriety design of leak detection port can be added to give a timely indication of seal derogation.

These liquid transmission flow cells can operate at temperatures as high as 400°C (280°C as standard) and at pressures up to 1500 psi. A choice of body materials (including Stainless Steel 316L and Hastelloy® C276) and a range of window seal options (including diffusion bonded windows and perfluoroelastomer seals) are available to ensure appropriate material compatibility for the application. To ensure optimum UV/Vis or NIR spectroscopic absorption features for analysis, optical transmission pathlengths are available from 1.0 to 10 mm. Optical fiber connectivity is ensured by industry standard SMA 905 connectors
