Liquid waveguide capillary cell, 100 cm pathlength

• Optical sample flow cell that combines an increased optical pathlength (100 cm) with a small sample volume (250 µL).
• Measure liquids in a continuous flow or using discrete samples
• Connects with 600um core optical fibers to fiber optic spectrometers and light sources via SMA terminations
• Efficient measurement of low-volume or low-concentration (ppb-ppt) aqueous samples. 
• Functions with most liquids(with the exception of perfluorinated solvents) having a refractive index ≥ 1.30
• Absorbance measurements can be performed in the UV, VIS, and NIR ranges to detect low sample concentrations in a lab or process environment.

  Benefits
