ASTM E 191 Document Information:
Title
Standard Specification for Apparatus for Microdetermination of Carbon and Hydrogen in Organic and Organo-Metallic Compounds
ASTM International
Publication Date:
Jun 15, 1964
Scope:
This specification covers apparatus and basic equipment for the
determination of carbon and
hydrogen in organic and organometallic compounds along the lines of
the conventional method of
Pregl, but with modifications more in line with modern practice. Owing
to the diversity of
apparatus by which correct results can be obtained, this specification
is intended to indicate what
is acceptable rather than what is mandatory.
NOTE 1 - Specifications for several items subsequently listed were
developed by the Committee for
the Standardization of Microchemical Apparatus, Division of Analytical
Chemistry, American Chemical
Society.(Footnote 2)
The values stated in inch-pound units are to be regarded as the
standard. The metric equivalents of
inch-pound units may be approximate.
