.~ Sampler, constituent separation, sample handling, or sample preparation
DEFINITION
Classification: 73/64.56
Sampler, constituent separation, sample handling, or sample preparation:
(under subclass 53.01) Subject matter combined with means for obtaining a predetermined amount of a liquid to be tested, for treating a liquid sample in preparation for its analysis or for isolating individual components of a liquid prior to analysis thereof.
(1) Note. "Sampling" includes: (a) Transporting or handling previously obtained samples of Liquid in preparation for analysis, or (b) introducing previously obtained liquid samples in preparation for analysis, or (c) the preparation of a liquid sample prior to the analysis thereof.
