Melting Point Determination
www.thinksrs.combecause even small quantities of impurities change the melting point, or at least clearly enlarge its melting range. Melting point determinations are more than just a classroom exercise in the organic chemistry lab. The test is still an important technique for gauging purity of organic and pharmaceutical compounds.

chem320.cs.uwindsor.careacting with the precipitant. e.g., In the gravimetric analysis of Be2+, Mg2+, Ca2+ or Ba2+ with the reagent N-p-chlorophenylcinnamohydroxamic acid, impurities such as Ag+, Mn2+, Zn2+, Cd2+, Hg2+, Fe2+, and Ga3+ are kept in solution by excess KCN. Post-precipitation: Impurities collect on the pure precipitated product while it is standing in the

www.ema.europa.eu• Testing for impurities can be either a quantitative test or a limit test for the impurity in a sample. Either test is intended to accurately reflect the purity characteristics of the sample. Different validation characteristics are required for a quantitative test than for a limit test.
Titrimetric Analysis: Methods
facultystaff.richmond.eduKjeldahl analysis is often used in the analysis of surface water and wastewater. The total Kjeldahl nitrogen (TKN) content of a water sample is a measure of the total concentration of nitrogen in the –3 oxidation state in the sample: ammonia/ammonium plus organic nitrogen. Kjeldahl analysis is also
