What's The Purpose Of Distilled Water. The purpose of using distilled water in the cuvette of the spectrophotometer is to calibrate the instrument. The blank is used so the absorbance.
The purpose of using distilled water as one of our test substances is that in a way it controls the experiment. Some people claim distilled water is the purest water you can drink. Contaminants in any other substances apart from distilled water are a risk towards the accuracy of the experiment.
Distilled water as a blank Basically the purpose of the blank is to provide a solution without albumin so that you can measure the absorbance in the absence of albumin to provide a baseline for the rest of the measurements.
There is a growing concern about toxins in our environment Distilled Water can help. Distilled water is still extremely pure but not to the same extent as deionized water which has had all ions removed. So to zero out the absorbance of compounds other than the analyte being determined distilled water is used as a blank. The blank is used so the absorbance.
