Abstract: A system and method are disclosed for analyzing samples, which includes a spectrometry system for detecting components of a sample; a gas chromatography column for separating the components of a sample; a first sample unit for receiving a first sample from a sample source; and a second sample unit for receiving a second sample from a sample source. Each sample loop unit allows independent processing of samples in preparation for analysis.

Abstract: Components resolved in time by a separator accumulate in a sample cell and are analyzed by electromagnetic radiation-based spectroscopic techniques. The sample cell can be configured for multiple path absorption and can be heated. The separator can be a gas chromatograph or another suitable device, for example a distillation-based separator. The method and system described herein can include other mechanical elements, controls, procedures for handling background and sample data, protocols for species identification and/or quantification, automation, computer interfaces, algorithms, software or other features.
