Why Are Absorbance Values Above 1 Inaccurate
Absorbance Values Greater Than or Equal to 1.0 Are Too High. If You Are Getting Absorbance Values of 1.0 or Above, Your Solution Is Too Concentrated. Simply...
Absorbance values greater than or equal to 1.0 are too high. If you are getting absorbance values of 1.0 or above, your solution is too concentrated. Simply dilute your sample and recollect data . … At an absorbance of 2 you are at 1%T, which means that 99% of available light is being blocked (absorbed) by the sample.
Why can absorbance not be greater than 1?
Absorbance more than one is possible. here the intensity of incident light is equal to the intensity of transmitted light hence the ratio is one and log 1 = zero absorbance. Absorbance one means the 90% light has been absorbed.
Why are absorbance values different?
The main reason absorbance values of a given sample will vary is the nature of optical instrumentation. There are many different types of spectrophotometers, each of which use different light sources, detectors, and optics, including diffraction gratings or prisms.
