5.2.2 After every use of curettes wash with water & then methanol, clean with tissue paper and keep
in curette Box.
5.3 Calibration
5.3.1 CALIBRATION FOR ABSORBANCE
5.3.2 Prepare a solution of potassium dichromate spectroscopy grade as per IP 2014
5.3.3 Take the absorbance of Potassium dichromate solution (60 mg dilute to 1000 ml dissolve in 0.005 M of
H2SO4) at following wavelengths 235 nm, 257 nm ,313 nm, 350 nm
5.3.4 Take the absorbance of Potassium dichromate solution (60 mg dilute to 100 ml dissolve in 0.005 of H2SO4) at 430 nm.
5.3.5 Calculate the (1% 1cm) values corresponding to above wavelengths by following formula.
Absorbance x 10
E (1% 1cm) = ————————————–
wt, of Pot. Dichromate in gm
nm = (235, 257, 313, 350 & 430)
Calculated value of E (1% 1cm) should lie between the following permissible
—————————————————————————————
Wavelength E (1% 1cm) Limits
(um)
—————————————————————————————
235 124.5 122.9 to 126.2
257 144.5 142.8 to 146.2
313 48.6 47.0 to 50.3
350 107.3 105.6 to 109.0
430 15.9 15.7 to 16.1
5.3.6 Control of Wavelength
Sample Preparation: Prepare a 4% w/v of Holmium Oxide in 1.4M Perhloric Acid
| Sr. No. | Wavelength | Observed Wavelength | Acceptance Criteria |
| 01 | 241.15 nm | 240.15 to 242.15 nm | |

| 04 | 536.30 nm | 533.30 to 539.30 nm |
5.3.8 Prepare 0.02%v/v solution of toluene in hexane spectroscopy grade solvent.
5.3.9 Take the absorbance to the above solution at 269nm and 266nm.
5.3.10 Limit of Stray Limit
5.3.11 Prepare 1.2 % w/v of potassium chloride in water.
5.3.12 Calibration Frequency
Once in 6 months and after each maintenance job.
