Web9 mrt. 2024 · A standard curve is constructed after obtaining the %T/Abs readings from a number of solutions of known concentration (standards) used in a reaction or procedure. After the readings are obtained each is plotted on semi-log (% transmittance) or linear (absorbance) paper against the corresponding concentration. WebStandard curve–making and using You need to produce a graph showing the linear relationship between the OD of the solutions (e.g. cordial) at various concentrations. That …
Webwhat this standard curve is. Then, we will learn how to use a spectrophotometer which is a device that allows us to look at wavelength of light and the absorption for a given wavelength of light. From all of this information, we will create a curve known as the standard curve, and use it to asses some unknown samples.
