Gas flow cell GUIDED WAVE™

UV-NIRUV-Visprocess

Ideal for Online Gas Measurement For measuring gases online by spectroscopy, a longer pathlength is usually necessary because of the low density of gaseous streams. A longer cell, while being very effective, is also more difficult to design. For example, transmission probes for gas measurements must be aligned over a greater distance and must permit easy servicing without upsetting the optical focus of the cell. Additionally, many gas streams are considered hazardous making it critical that the sealing mechanism is both reliable and durable. Our GUIDED WAVE™ Gas Process Flow Cell meets or beats most standards for use found in chemical plants, refineries, food, and food supplement processing facilities, semiconductor or electrical component fabrication shops, and pharmaceutical manufacturing plants. Available in a variety of alloys and matched with several elastomeric O-ring types. Better Optical Efficiency For UV-VIS and NIR Measurements Descriptively speaking, most true transmission Gas Cells may be viewed in symmetrical halves. Each half comprises both optical and mechanical parts integrally assembled to transmit and receive a focused beam of light that has traversed the sampled stream. The major issues with any kind of transmission flow cell involve establishing and maintaining the optical alignment of the two halves and ensuring that the pathlength is constant and reproducible. When these two issues are resolved well, the result is better optical efficiency. And better optical efficiency leads to significant long-term advantages – more accurate analysis, more robust calibrations, and greatest analyzer uptime.
