  • A New Method for the Determination of Sucrose

    The work performed shows the reliability of this method. A model linking sucrose solution absorbance and mass percentage of glucose and fructose has been developed using experimental design. The results obtained show that all the investigated factors (sucrose concentration, mass percentage of glucose, and mass percentage of fructose) have a

  • Flotation Technique for Fecal Parasite Concentration Methods

    By exploiting the density of the parasites, particularly eggs, it allows the parasites to float to the top of a dense solution (final specific gravity of about 1.20) and can then be skimmed from the top of the tube. The most commonly used reagent is zinc sulphate. Operculated eggs as well as schistosoma and infertile Ascaris eggs are not easily recovered by this method. Also trophozoites are

  • Application of optical methods to determine the

    Two optical methods were used to determine the concentration of sugar (sucrose) solution. The first employed a hollow perspex prism, a prism spectrometer and a monochromatic light source. The angles of minimum deviation for different sugar samples were determined, whose values were used to compute the refractive indices of these samples.
