Abstract: Described are techniques for event notification in a data system. Severity levels associated with event messages with-in the data system are specified. The data system is used to control operation of one or more instruments performing analysis of a sample. Event notification subscription criteria for a user of the data system in specified. Notification are provided to the user regarding a plurality of even occurrences in accordance with the event notification subscription criteria.

Abstract: A method and apparatus for automating the qualification process for chromatographic systems. Automation technology and regression analysis are used for qualifying a chromatography system. The trained operator prepares the chromatography system to ensure that the samples, solvents, and the separation column are ready for analysis. The qualification of the detector, the solvent delivery system, the sample manager, the gradient proportioning system, the column heater, and the delay volume of the chromatography system are completed without the necessity of operator intervention. Regression analysis is performed to compute performance statistics that demonstrate the accuracy, linearity, and precision of the chromatographic system and quantify its suitability for chromatographic analysis.
