LPC Longpass Flow Cells couple to Ocean Optics high-sensitivity fiber optic spectrometers and compact light sources for simple, efficient measurement of low-volume or low-concentration aqueous samples.
Multiple pathlength options -- pathlengths range from 50-500 cm
Small internal sample volume -- as low as 125 µL
Easy to use -- inject sample with a syringe or connect to a pump
LPC Longpass Flow Cells use a capillary tube as both the sample compartment and the waveguide for light. The sample is introduced with a syringe or a pump into the fluidic ports mounted on the face panel. Optical fibers connect to SMA 905 fittings to deliver and return light to a spectrometer.
The LPC Flow Cells are available in 50, 100, 250 and 500 cm pathlengths. Internal sample volumes range from 125-1,250 µl, respectively. Cells are optimized for UV-VIS response.
All LPC Flow Cells couple easily via SMA 905 terminations to Ocean Optics fiber optic spectrometers and accessories.
For UV applications -- especially <275 nm -- we recommend using the shortest possible length of LPC Flow Cell tubing, as most fluids will absorb UV energy. However, for UV applications between 275-360 nm, it is possible to use the standard 100 cm flow cell with a UV-Vis spectrometer and deuterium-tungsten halogen light source configuration, and still get good results.
