Abstract: A gas analysis system with an FTIR spectrometer preferably utilizes a long path gas cell, a narrow band detector, and an optical filter that narrows the detection region to measure hydrogen sulfide.

Abstract: Components resolved in time by a thermal desorption separator accumulate in a sample cell and are analyzed by electromagnetic radiation-based spectroscopic techniques.

Abstract: A system and method for determining impurities in a beverage grade gas such as CO2 or N2 relies on FTIR gas analysis for measuring non-sulfur impurities as well as SO2. CO2% also can be determined. A multiplexer selects a sample gas from multiple gas samples. Conversion of reduced sulphur present in some impurities to SO2 is conducted in an oxidizing furnace. Climate control and measurements of oxygen gas impurities also can be provided.

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: A system and method for determining impurities in a beverage grade gas such as CO2 or N2 relies on a coupling of FTIR analysis and UV fluorescence detection. Conversion of reduced sulphur present in some impurities to SO2 can be conducted using a furnace. In some cases, CO2% also is determined.

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.
