Transmission and Raman Flow Cells
for Process Monitoring
Mainstream offers a line of process flow cells for in-line monitoring of liquid streams via fiber-coupled spectrometers. These flow cells, originally designed for military applications, are well suited to the most demanding industrial environments.
Compact, Double-pass Visible/NIR Flow Cells
Easy to package with co-located fiber-optic connectors- Compact, folded, optical path design
- Compactness of transflectance probe, performance of transmittance probe
- Lensed design with very low transmission losses
- Lenses and turning optics not exposed to fluid
- Adjustable path length
- Fixed or adjustable focal length optics
- Patent pending
Industrial Raman Flow Cells & Probes
Probe is co-linear with fluid connections for packaging- Design allows for probe to be removed without breaking fluid connections
- No need to purge lines after removal of probe for recalibration
- Mates with custom InPhotonics probe built to our specifications
- Probe features hardened shutter, jacketed cables, and strain-relieved end terminations
- High temperature (HT, 290°C) and ultra-high temperature (UHT, 500°C) variants available
Custom Process Flow Cells
Custom design and fabrication for the most demanding applications- Chemical, automotive, and military applications
- Ultra-high temperatures and pressures
- Engineered to suit; tested in-house
Compact, Fiber-coupled, In-line Analyzers
- Short-wave IR (SWIR), UV-Visible, and Raman spectrophotometric analyzers
- Analyzers include spectrometer, light source, fiber optics, flow cell, and custom calibrations
- On-board programmable microcontroller for real-time chemometric data analysis
- Developed for fuel property monitoring and water quality monitoring
