SPECTROPHOTOMETRY OVERVIEW Spectrophotometry is a well-established analytical method, which has been used for decades in chemistry, physics, biochemistry, and chemical engineering for quantitative analyses. A light source and sensor are used to measure the intensity of light passing through a water sample…
Specific ultraviolet absorbance (SUVA) provides a general characterization of the nature of natural organic matter (NOM) in a water sample and is typically performed for the purpose of determining disinfection by-product (DBP) formation potential. SUVA is calculated by dividing the…
UV254, TOC, DOC, BOD and COD all provide measures of different aspects of the organic content in a water sample. Each of these parameters possesses a certain bias due to the nature of the particular test method: ABSORBANCE AT 254…
