Hello,

Why isn't it possible to load the calibration files (.gal format) in Clarity offline? If I want to analyze chromatograms with Clarity offline, I have to upload a .cal file (for calibration file). I also tried to save the calibration file done with Clarity as .cal file, but then I receive an error message in Clarity offline saying that the file can not be opened.

This should be possible. Have you set the instrument type in System, Configuration to the GPC mode? Clarity enables you to evaluate chromatograms both in standard (using the *.cal calibration to quantitate the compounds) and GPC mode (using the *.gal calibration to evaluate the molecular weight distribution).

The instrument must be set to GPC or GPC-PDA mode in System, Configuration. On such instrument the mode could be further toggled between GPC (default) and standard by the Settings, GPC Mode command. In Method Setup, both standard and GPC integration and calculation parameters could be specified. In Chromatogram window, only the selected mode parameters are available and you need to switch between the modes to evaluate the chromatogram in both.
