DEFINITION

Classification: 73/61.41

Content or effect of a constituent of a liquid mixture:

(under subclass 53.01) Subject matter wherein the determination is made by detecting or measuring the amount of or the presence of a constituent of a liquid mixture, the ratio of one constituent to at least another constituent, or the effect of a constituent of a liquid mixture.

23.2+, for similar processes and apparatus for gas analysis, particularly subclasses 23.35+ for gas chromatography and subclasses 28.01+ for determining the solid content of a gas.

64.41+, for tests of gelling or coagulation even though this effect may be disclosed as being caused by the presence of some constituent.

863.21, for samplers, per se, which isolate particulate matter from a liquid for latter analysis or inspection.
