11.2 PHYSICAL ANALYSIS
11.2.1 Test of Physical Form:

Check the sample and confirm its physical form, it should be fine powder.

11.2.2 Test of Colour:

Confirm the colour of the material by comparing with standard from colour chart, it should be off white.

11.2.3 Test of Reconstitution:

Weigh accurately on analytical balance 263 mg of sample, put it in the vial, reconstitute it with 2 ml of Water for Injection, after reconstitution it should be 2.1 ml (± 0.1 ml).

11.2.4 Test of Clarity:

Weigh accurately on analytical balance 263 mg of sample, put it in the vial, reconstitute it with 2 ml of Water for Injection. After reconstitution check the clarity, it should be clear solution and without any visible contamination.

11.2.5 Test of Reconstitution Time:

Weigh accurately on analytical balance 263 mg of sample, put it in the vial, reconstitute it with 2 ml of Water for Injection and note the time, it should not be more than 1 minute.

11.2.6 Test of pH After Reconstitution:

Weigh accurately on analytical balance 100 mg of sample and make the volume upto 100 ml with distilled water in the beaker. Take 50 ml from the resulting solution and measure the pH of solution on pH meter; it should be 4.5 to 6.5 at 25°C +- 2°.

11.2.7 Test of Moisture Contents:

Weigh accurately 10 g of sample on moisture balance. Adjust the temperature at 85°C, start drying the sample. At the end balance show percentage loss of moisture, moisture contents should not be more than 5%.

11.3 Record the result of Physical Analysis on quality report.

11.4 CHEMICAL ANALYSIS: BP/USP
11.4.1 Examination of Cefotaxime by IR spectrum:

Take dried sample to 5mg of Cefotaxime sodium and thoroughly mix with 95mg of dried standard of potassium bromide in pastel mortar.
Fill Macro cups with provided funnel like instrument and draw the spectrum it should be complies the standard spectrum.

11.4.2 Identification Test of Sodium:

Make the paste of 500 mg of the sample with 0.5 ml of concentrated hydrochloric acid, Moisten the platinum wire with the paste and introduce into the flame of a Bunsen Burner; golden yellow colour flame should produce.

11.4.3 Contents of Cefotaxime Sodium:

11.4.3.1 Standard Preparation:

11.4.3.1.1 Weigh accurately on analytical balance standard Cefotaxime Sodium equivalent to 100 mg of Cefotaxime Sodium, make the volume upto 100 ml with distilled water in the volumetric flask.
