Spectroscopy Videos

UV/VIS/NIR absorbance spectroscopy is governed by Beer's Law, where the absorbance signal is proportional to chemical concentration, light path length and the compound’s specific molar absorption coefficient. Typical optical pathlengths of cuvettes and flow cells are between 0.1 cm and 10 cm. Longer pathlengths are difficult to achieve due to mechanical constraints. WPI solved this problem with the LWCC Liquid Waveguide Capillary Cells. LWCCs are fiber optic flow cells that combine an increased optical pathlength range from 10–500 cm with small sample volumes ranging from 2.4 µL to about 3 mL. Compared with a standard 1 cm cell you can expect to achieve a 10-500 fold increase in sensitivity.
