ASTM-E2106 › Standard Practice for General Techniques of Liquid Chromatography-Infrared (LC/IR) and Size Exclusion Chromatography-Infrared (SEC/IR) Analyses
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This practice covers techniques that are of general use in qualitatively analyzing multicomponent samples by using a combination of liquid chromatography (LC) or size exclusion chromatography (SEC) with infrared (IR) spectrometric techniques. The sample mixture is separated into fractions by the chromatographic separation. These fractions are subsequently analyzed by an IR spectroscopic method.
1.2 Three different types of LC/IR techniques have been used to analyze samples (1,2). These consist of eluent trapping (see Practices E334), flowcell and direct deposition. These are presented in the order that they were first used.
1.3 The values stated in SI units are to be regarded as standard.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
