STP FOR THE DETERMINATION OF TOTAL SOLID IN ASAVA/ARISTA

1.0 PURPOSE

The purpose of the document is to establish a method for the determination of Total Solid In Asava/Arista.

2.0 SCOPE

This standard testing procedure is suitable for the method for determination of Total Solid In Asava/Arista.

3.0 RESPONSIBILITY

The expert and trained chemist are responsible for following this procedure. The technical manager is responsible for implementing this procedure

4.0 REQUIREMENTS

4.1 Apparatus

4.1.1 Evaporating Dish

4.1.2 Hot air oven.

4.1.3 Water bath

4.2 Glassware

4.2.1 Desiccator

4.3 Reagent

N.A.

5.0 PROCEDURE FOR TOTAL ASH

5.1 Transfer accurately 50 ml of the clear Asava/Arista in an Evaporating dish, which has been dried to a constant weight.

5.2 Evaporate to dryness in the water bath.

5.3 Dry at 1050 for 3 hours.

5.4 Cool the dish containing the residue in a desiccator for a minimum of 30 minutes.

5.5 Weight the sample immediately to a constant weight.

.   

6.0 Calculation

                                             

                Total solid % (w/v)=    (W1-W)/V ×100

                                                

                 

             Where,

W = Weigh of the empty dish, in g

W₁ =Weigh of dish+ sample after drying, in g

V = Volume of the sample taken for test, in ml
