PHOTOMETRIC ACCURACY

Prepare 1.065 % w/v. 0.710 % w/v, 0.355 %w/v solution of Potassium Nitrate (Previously dried at 130^oC) .

Go to Photometric mode

1. press Ctr+M

2. Add wavelenth 302 nm{Select RAW DATA}

3. Auto zero

4. Then keep the Potassium Nitrate Solution in the sample cell holder & using water as a blank. 

5. Close the cell compartment.

6. click Start

7. And record the observed Abs.
