Ultra-compact fiber-optic flow cell for UV/VIS and NIR applications with a 0.5 mm optical path length, 5 µl internal volume, and a broad spectral range from 200 to 2400 nm. Thanks to SMA-905 fiber connectors and 10-32 UNF fluid connections, it can be easily integrated into HPLC, microfluidic, FIA, and process analysis systems.
This compact, biocompatible fiber-optic HPLC flow cell combines highly durable PEEK with high-quality quartz glass and enables precise measurements in the UV/VIS and NIR spectral ranges. The short optical path length prevents signal clipping and makes the flow cell ideal for high-concentration samples without dilution. Thanks to its high pressure resistance and robust design, it is ideally suited for demanding applications in UHPLC, HPLC, FIA, GFIA, as well as for inline and process analytics.
