The standard software provides a graphical user interface for TLC scan, gamma-ray spectroscopy, detector control, data acquisition, quality assurance (QA) and database management. The provided factory programmed protocols may be supplemented by user defined protocols. The protocols provide automatic control of the detector scan, the acquisition as well as graphical display and analysis. QA is assured by the quality control procedure and trending analysis of the QA data as a function of time. The database option supports the extraction and re-analysis of all stored data. Various procedures needed for radio chromatography are implemented in the software of RTLC2419. The chromatography procedure starts with definition of “Drop Point” and “Front End” where the user can define the starting and end of chromatography. User can also define the “Time” for the whole test and the “Repeat” number of test. Together with these information, the user provides various information that will be printed in the final report and will be used to identify the person who perform the test and its exact date and time. After this initialization setting, the chromatography test will be started and in the “Time” parameter defined by the user, the test will end. By finishing the scan, various features for the device will be activated. The user can define a specific energy range and the device will immediately visualize the chromatogram for the corresponding range. On the other hand, the user can also define an interval along the test length and software will immediately generate the spectrum corresponding to that interval. Various smoothing operations for both chromatogram and spectrum are applicable in the software. For chromatographic analysis, the user can easily define “Radiopharmaceutical”, “impurity” and “Background” regions and then software will perform the analysis and show the result in the table placed on the upper right corner of the software. The report generated by the user present a summary result of the test where analysis result table, whole spectrum and chromatogram are displayed. Also the color of final report can also be customized based on the user preferences. Altogether RTLC2419 is a total solution for radio chromatography tests which provide the user with various analysis setting parameters, data visualization procedures and reports.
