ADVANTAGES AND LIMITATION OF INSTRUMENTAL METHODS OF ANALYSIS

Advantages of instrumental methods:-

  1. A small amount of a sample is needed for analysis.
  2. Determination by instrumental method is considerably fast.
  3. Complex mixture can be analysed either with or without their separation.
  4. Sufficient reliability and accuracy of results are obtained by instrumental method.
  5. When non-instrumental method is not possible, instrumental method is the only answer to the problem.

Limitation of instrumental methods:-

  1. In general, instrumental methods are costly because of cost, maintenance and trained personnel required for their handling.
  2. The sensitivity and accuracy depends upon the type of instrument.
  3. Specialized training for handling instrument is required.
  4. There is frequent need of checking results with other methods.
  5. In some cases, instrumental method may not be specific.

Applications of Conductometry

Some applications of conductometry are discussed here, conductometry in analytical chemistry is used to measure the progress of chemical reactions. Conductometric titration is carried out in order to measure the  electrical conductivity of the reaction mixture. This type of titration gives a sharp end point for the colored solution.

This type of titration is used to check water pollution in lakes as well as rivers.It is also used to check the alkalinity of the fresh waterSalinity of the sea water can also be checked by this method.It is also used to trace antibiotics.Used for tracing microorganism in food microbiologyTo check the solubility of sparingly soluble salts.Purity of distilled water and de ionised water can determined.
