X-ray powder diffraction (XRD) is a rapid analytical technique primarily used for phase identification of a crystalline material and can provide information on unit cell dimensions. The analyzed material is finely ground, homogenized, and average bulk composition is determined.

Stock solution of vita­mins, amino acids and hormones should not be stored for indefinite period and should be kept in a deep freezer chamber. The widely used culture medium was formulated by Murashige and Skoog (commonly called MS medium), so the proce­dure for the preparation of stock solution of MS medium (1962) is given below:

The Phenol - Sulfuric Acid method is an example of a colorimetric method that is widely used to determine the total concentration of carbohydrates present in foods. A clear aqueous solution of the carbohydrates to be analyzed is placed in a test-tube, then phenol and sulfuric acid are added. The solution turns a yellow-orange color as a result ...
