1.0  OBJECTIVE

       To calibrate the equipment for reliable and accurate results.

2.0  SCOPE

       This procedure is applicable to the infrared spectrophotometer, installed in quality control department.

3.0  RESPONSIBILITY

3.1  Doing      : Technical Assistant
3.2  Checking : Executive /Manager

4.0  ACCOUNTABILITY

       Head of the Department

5.0  PROCEDURE

       Frequency of calibration: Once in month

5.1  Operate the instrument as per SOP.
5.2  Put the reference polystyrene film (0.05 mm thick) in the sample holder and scan.
5.3  Compare the obtained spectrum with the reference spectrum for the following wave numbers as well as transmittance at shown wave number. Record the results as per annexure I.
