MicroLWCC is a new fiber optic low volume flow cell for UV/VIS/NIR absorbance analysis. Based on WPI’s established liquid core waveguide technology, the analyte solution functions as the core of a fluid filled light waveguide. Wetted parts in the sample cell light path are PEEK, fused silica and PTFE. Optical fibers are used to transport light to and from the sample cell. The cell can be used in biochemistry for DNA, RNA & protein quantification, colorimetric nutrient and trace metal analysis, drug discovery and dissolution testing, process control, and HPLC analysis.
