Our GUIDED WAVE™ O-Ring Single Sided Transmission Probe (O-SST) is ideal for in-process fiber optic probe is needed in a corrosive process stream containing strong acids, bases, or cyanides. The O-SST performs similarly to our more popular gold alloy sealed SST probe but uses polymer O-rings to seal the sapphire windows. Like the SST probe, the O-SST has high optical throughput for low noise inline spectroscopy of complex solutions. Inline probes eliminate costly and problematic fast loops and sample systems. The O-SST is available in several convenient pathlengths, probe lengths, O-ring materials and most common chemically resistant stainless-steel alloys.
- Corrosion resistant construction
- Rugged design
- O-ring process seals
- Sealed against ambient moisture infiltration
- High optical throughput for low noise spectroscopy
- Collimated beam
Our O-SST Probe is designed to withstand corrosive processes especially those containing nitric acid or cyanides that attack our gold alloy sealed SST probe. The body of the probe is built from 316L stainless steel (standard, however, several other alloys are available by special order). The probe’s sapphire optical windows are sealed to the probe body with polymer O-rings chosen to be compatible with your process.
Operating Range and Configurations
The operating range of the O-SST Probe will be determined primarily by the choice of o-ring material. The maximum operating temperature and pressure are 250°C and 1000 psi. This probe is available in five standard lengths, nine optical pathlengths, and UV, visible and NIR versions. Other probe lengths and pathlengths are available by special order.
Exceptional Light Transmission
The O-SST Probe provides exceptional optical performance. Typically, peak transmission exceeds 40%. That means more signal, lower measurement noise, and lower limits of detection.
The probe, or sample interface, is a crucial component of a complete analyzer system. For optimal performance, the probe must be ‘’optically matched’’ with the spectrometer and with the optical fiber that transmits the spectral data. The O-SST Probe (and each of our Guided Wave optical probes) is matched to our analyzers and fiber to achieve the highest possible performance. It is also compatible with many other fiber optic analyzer brands according to fiber diameter and spectral range.
