Vortex | Flange-mounted NIR process cell

Vortex™ Process Flow Cell

The Vortex™ process flow cell is a flange-mounted liquid flow cell with ANSI or DIN flange fittings. It features sapphire optics and SMA 905 fiber connections as standard. It is designed for in-situ monitoring of industrial chemical process streams by NIR spectroscopy. The flange fittings make it possible to install directly on the process plant or in a short by-pass loop. Contact us today to discuss your process spectroscopy needs.

DIN or ANSI flange-mountings: sizes from ANSI 1/2" or DIN 10 upwards are available.
Pathlengths: can be factory set at minimum 1.0 mm, maximum 10 mm.
Sapphire optics: for NIR spectral range
Factory-aligned optics: ensures optimum measurement stability throughout the lifetime of the cell.
Optional Tell-Tale and Cleaning ports: for preventative maintenance and monitoring.

The Vortex cell can operate at temperatures up to 280°C and at elevated pressures.
Flange classes PN6, PN10, PN16, PN25 and up (European) and 150lb or 300lb (US)
A choice of body materials are available for the customisation of your flow cell. We manufacture in Stainless Steel 316L as standard but Hastelloy® C276, Titanium, Zirconium 702, and other grades of Stainless Steel are available upon request.
Window sealing materials are generally perfluoroelastomers such as Kalrez, Polymax, or Viton of various grades.
To ensure optimum NIR spectroscopic absorption features for analysis, optical transmission pathlengths are available from 1.0 to 10 mm.
Specac process cells can be connected remotely to the widest choice of commercially available FT-NIR spectrometers using standard SMA 905 connectors. A large range of process analytical applications on a petrochemical site can now be realized simultaneously with just one spectrometer and an optical multiplexer by the combination of Specac gas, vapour and liquid cells.
Particular attention has been paid by Specac in the careful selection of appropriate IP65 rated protection for the fibre-optic cable connection to ensure peace of mind for the process engineer.
By using highly polished sapphire windows and optimized flow patterns the risk of window fouling in raw chemical process streams is greatly reduced.
The ruggedness of the cell also allows for harsher in-situ cleaning methods like high-pressure steaming or using elevated temperatures for short periods of time.
