DEFINITION

Classification: 436/43

AUTOMATED CHEMICAL ANALYSIS:

(under the class definition) Processes wherein sample(s) are

analyzed by using self-operated mechanisms or devices.

(1) Note. Included in the subclass are methods of controlling the operation of the self-operated analyzing system, i.e., process control of a chemical test procedure.

(2) Note. Also included in the subclass are the methods of using the various subcombinations of the self-operated analyzer. Exemplary of such subcombinations is the method of aspirating, using aspirating devices of claimed structure when in such self-operated devices and the use is solely disclosed as in a self-operated chemical analyzer.

(3) Note. This class does not provide for processes of automatic or condition responsive control of a chemical process except in the case (a) where the claims are so broad as to be unclassifiable in any other chemical class or (b) where there is effected some chemical test in combination with a mechanical or class which excludes chemical reactions or electrical process classifiable in a class which excludes chemical reactions or (c) where the process is that of condition responsive control of an analytical chemical test.
