LWCC-5000 Series

The LWCC-5000 series liquid waveguide capillary flow cells are new fiber optic flow cells with a larger inner diameter of 1 mm. High UV/VIS/NIR absorbance and turbidity applications are possible with this new flow cell, based on WPI’s established liquid core waveguide technology. The result is an enhancement of sensitivity and improved limits of detection when compared with conventional spectroscopic sampling techniques. Wetted parts in the sample cell light path are PEEK, fused silica and Teflon. Optical fibers are used to transport light to and from the sample cell.
