Clarity Chromatography Station version 2.3 and an optional add-on module for gel permeation chromatography has been introduced. The module provides tools for analyzing data from gel permeation chromatography, while the software acquires data from any HPLC system with standard analog output. Each GPC module provides interactive and automated GPC analysis including recalibration and GPC reporting while also simplifying data retrieval. It also allows flow rate and multi-detector delay corrections and includes narrow, broad, broad-on-narrow, and universal calibrations. Key features of Clarity version 2.3 include better visualization of calculations and enhanced report customization. The software provides a calibration points history, display of deviations in all calibration points, and display of calibration curve residuum calculations. New printing options include predefined report styles or customized reports for individual needs.
