Quantitative procedures were, however, still classical in the tradition of gravimetric or volumetric assays with an initially weighed sample yielding, after chemical manipulation, a carefully precipitated, dried and weighed end product, or a solution of known compos978-94-010-5905-3978-94-011-4435-3

These can range from the quantitative analysis of blends, the homogeneity of mixes and the nature of various degradative processes, to the state of cure of rubber products.
