This practice establishes the standard techniques that are of general use in securing and analyzing samples in microgram quantities (microanalysis) by infrared spectrophotometry. These techniques include general microspectroscopy, analysis of gas chromatographic fractions, analysis of liquid chromatographic fractions, analysis of thin-layer chromatographic fractions, analysis of paper chromatographic fractions, analysis of gases evolved from a thermogravimetric analyzer, and infrared spectroscopy using a microscope.

1. Scope | ||||||||||||||
1.1?This practice covers techniques that are of general use in securing and analyzing microgram quantities of samples by infrared spectrophotometric techniques. This practice makes repetition of description of specific techniques unnecessary in individual infrared methods. 1.2?These recommendations are supplementary to Practices E168, E573, and E1252, which should be referred to for theory, general techniques of sample preparation, and calculations. 1.3?This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
