Process-Resistant Flow Cell Body Construction
Since no metal parts come in contact with the liquid stream, the design is ideal for processes where even parts per billion levels of metals contamination can create serious problems as in semiconductor fab etching and cleaning steps. The cell also performs well in the presence of extremely corrosive streams containing strong acids, bases, peroxides or halogenated compounds.
The Teflon Flow Cell operates at moderate temperatures and pressures. Specifically, safe upper limits for deployment are:
• Temperatures to 150 °C
• Pressures to 100 psi
Available in four standard pathlengths 2, 5, 10 and 20 mm, but other custom paths are available by special order.
Common Integration with Most Spectrometers
The Teflon Flow Cell is manufactured to facilitate full integration with any fiber optic system configured with SMA 905 connectors. Connecting the teflon flow cell with fibers having a core diameter of 400 to 600 micron to the NIR analyzer will provide the best optical performance. The Teflon flow cell is compatible with FT-NIR analyzers from other vendors.
Exceptional Light Transmission
Like other Guided Wave optical probes, the Teflon Flow Cell provides exceptional optical performance. Typical peak transmission exceeds 50%. That means more signal, lower measurement noise and lower detection limits. The flow cell can be completely dismantled, then reassembled without changing the sampling pathlength, an important feature when working with established NIR calibration models.
Compatible with All Guided Wave Analyzers
The sample interface is a crucial component of a complete fiber optic-based analyzer system. For optimal performance, the probe must be ‘’optically matched’’ with both the spectrometer and the fiber optic cable. The Teflon Flow Cell, just as is the case for all our Guided Wave probes, provides consistently high performance when used in combination with our analyzers and fiber
