UV-Vis Spectrophotometers

The Thermo Scientific™ GENESYS™ G5 UV-Vis Spectrophotometer serves as a core analytical instrument in our laboratory for aquatic chemistry and environmental monitoring. We routinely utilize its full ultraviolet-to-visible spectrum capabilities alongside user-defined calibration curves and self-prepared reagents to conduct precise nutrient assays for nitrate, nitrite, phosphate, and ammonia. Furthermore, its optics allow us to analyze solvent extractions of Chlorophyll-a at key absorption wavelengths to quantify algal biomass, as well as measure UV-absorbance coefficients to evaluate Chromophoric Dissolved Organic Matter (CDOM) dynamics in natural water systems.
