Longpass Flow Cell
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.
Features
-
Increased Sensitivity. Our 1-meter cell increases the absorbance signal by 100x compared to a standard 1-cm cuvette
-
Small Internal Volume. Just 200 L per meter
-
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 result is a 1-meter
(standard) cell with a tiny 240
l volume. The sample is introduced with a syringe or a pump into the fluidic ports mounted on the face panel. Optical fibers connect to SMA fittings to deliver and return light to a spectrometer.
The LPC Flow Cells are available in nominal 1-meter and 5-meter cell
lengths; custom lengths are also available. Actual effective cell length is marked on each unit.
Each LPC Longpass Flow Cell features 550 mm inner-diameter
fused silica tubing with an
internal volume of 240 mL/meter and
1/16"-1/32" compression fittings for liquid flow. LPC Flow Cells will work
with most organic and inorganic solvents.
All LPC Flow Cells couple easily via SMA
terminations to Ocean Optics fiber optic
spectrometers and accessories.
Technical Tip
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 1-meter flow cell with a UV-Vis spectrometer and
deuterium-tungsten halogen light source configuration, and still get good results.
