Absorbance - Wikipedia
WebAbsorbance can be calculated from percent transmittance (%T) using this formula: Absorbance = 2 – log (%T) Transmittance (T) is the fraction of incident light which is transmitted. In other words, it’s the amount of light that “successfully” passes through the substance and comes out the other side. It is defined as T = I/Io, where I ... WebA calibration curve is one approach to the problem of instrument calibration; other standard approaches may mix the standard into the unknown, giving an internal standard. The calibration curve is a plot of how the instrumental response, the so-called analytical signal, changes with the concentration of the analyte (the substance to be measured ... Web3.2.2 Specific UV-absorbance. Specific UV-absorbance (SUVA) is defined as the UV absorbance of a given sample at 254 nm divided by the DOC concentration of the sample. This ratio describes the hydrophobicity and hydrophilicity of NOM in water; a SUVA > 4 indicates mainly hydrophobic and especially aromatic material, whereas a SUVA < 2 ... red river college it support
