Definition Liquid Waveguide Capillary Cells (LWCC) are fiber optic cells that combine an increased optical pathlength (50-500 cm) with small sample volumes (125-1250 mL). They can be connected via optical fibers to a spectrophotometer with fiber optic capabilities. Ultra-sensitive absorbance measurements can be performed in the ultraviolet (UV), visible (VIS) and near-infrared (NIR) to detect low sample concentrations in a laboratory or process control environment.
