Scientific Graphics Software

ChemSW, Inc.t!Pro Plus is a scientific graphics software program for Microsoft Windows that was specifically designed to generate analytical control charts for laboratory quality control programs. It includes a batch mode that will automatically graph control charts on as many analytes as is needed with the correct format for each chart. These batch files can be saved and invoked by executing the batch file. This program provides full importing and exporting capability from an instrument report by copying and pasting. By using the Windows Clipboard one can include the actual control chart presentation directly in your word-processing report. The program generates accuracy and precision graphs using two different scaling methods: fixed interval and Shewhart X-bar (standard deviations).

There are three different types of data that the program can plot: Reported Value data (plots just the values provided), Percent Recovery data (calculates percent recovery and then plots those values), and Absolute Difference (plots the calculated difference between replicate sets). Control charting protocols specified by ASTM, EPA, and Standard Methods have also been implemented and use the same
