Abstract

Many biochemical experiments involve the measurement of a compound present in a complex mixture. The most widely used method for determining the concentration of biochemical compounds is colorimetry. This chapter covers the photometry, colorimeter, preparation of solution for investigation, technique, relationship between absorbance and transmittance, selection of filter in colorimetric estimation, and application of colorimeter. Colorimetric procedure is widely used in laboratories for the estimation of various biochemical compounds in various biological samples like blood, plasma, serum, CSF, urine and other body fluids.
