DataApex Clarity, GC and HPLC software

Clarity is an advanced chromatography station designed to acquire and evaluate data from up to four chromatographs at a time. Clarity - a top product in its category - represents a universal solution for laboratories. It enables the user to acquire data from any commercially available chromatograph with standard analogue output. Up to four chromatography systems, each of which can be equipped with up to four detectors, can be connected simultaneously. The chromatography station package includes an A/D converter (internal PCI card or external USB box) and the corresponding Clarity Software.

Algorithm for detection of peaks

Highly responsive algorithms enable users to detect hundreds of peaks in each chromatogram. Data from the analysis can naturally be reprocessed without the necessity of repeating the analysis.

Integration

All integration parameters are saved in the integration table. Parameters such as Peak Width and Threshold are programmable in time. There are a total of 27 integration parameters incorporated to ensure the optimal integration of peaks. Most of these parameters can be applied also with the mouse from icons on the toolbar. Every change of basic integration parameters in the chromatogram window will force immediate reintegration.

Method

All parameters for data acquisition and peak integration, including baseline operations and link to the calibration file are saved in the template method. After creating of a chromatogram, a copy of the template method becomes a part of the chromatogram file.

Multi-detector measurement

Once a measurement has been completed within the framework of one instrument and more than one detector (up to four), signals are simultaneously displayed and accompanied by a legend identifying each signal and detector. Users may select the number of signals displayed according to preference.

Calibration

The Clarity Station uses linked calibration. Calibration curves are saved in a separate file, to which the template and chromatogram methods are referring. After updating or modifying this calibration file, results in all chromatograms linked to this file will be automatically recalculated upon opening. Although the calibration is linked, the current states of the calibration file and methods are stored in the chromatogram every time it is saved (using the commands Save, Print or Export). The chromatogram with its former method settings and calibration curves may thus be opened from any prior saved state.

Calibration calculations

Clarity offers the ability to calculate using external or internal standard methods. There are six types of curves to fit calibration points with the option to include a zero point. The station allows you to select automatic or manual (interactive) method of data transmission from the calibration standard into the calibration file. Groups of peaks may also be calibrated.

Method of reference peaks

Use reference peaks and or customizable identification windows for individual peaks to enhance the accuracy of compound identification.

Editing and recalibration

Browsing and adjustment of calibration data is simple thanks to the consolidation of all compounds in a single global calibration table. The calibration table and curve of each substance is placed separately on the relevant tab in the main calibration window.
