Calibration

PowerStream will automatically define a time window in which a peak should appear, to be correctly recognised and named in the component peak table. The width of the time window is set after measuring the widest half widths of the asymmetrical peaks, i.e. on the widest trailing side of the peak. The default value can be changed by the user.

When a peak is highlighted in the peak component table, the time window is displayed superimposed on the appropriate peak. If the peak has been calibrated the concentration, peak height and area tables are displayed together with the associated calibration curve as shown in the lower window. In this case a linear curve fit was chosen. A choice of linear, quadratic or cubic fit is provided.

Report Formatting

The final report may be user configured and a template defined to include as much or as little information as is required. The basic format will have four segments to a single page, the header information, the chromatogram, the results table and a footer. Each of these separate sections can be sized and their contents defined, easily and rapidly using dialogue boxes.

Should a larger chromatogram format (up to a whole page), or all and every detail of the results, be required, a second page may be additionally defined.
