Abstract: Exemplary embodiments provide methods, mediums, and systems for creating a processing activity map for an analysis workflow in a chromatography experiment. A result set for the analysis workflow may be created and maintained throughout various stages of the analysis workflow. When certain trigger conditions are met, the in-use version of the result set may be persisted. For example, a read-only historical archive copy of the result set may be created, while the previous version of the result set is used in further stages of the analysis workflow. The trigger conditions may include a number of situations such as moving backwards in the workflow and making a change, moving across gated step boundaries in the analysis workflow, or receiving an instruction to clear the result set. The persistent, historical copies of the result set may be used to support auditing of a compliance-driven analysis process.

Abstract: In an image-forming device, a drum cartridge and a developing cartridge are detachably attached to a frame. A controller is configured to perform: a drum replacement necessity determination process; and a mode switch process. The drum replacement necessity determination process determines, based on life information for the drum cartridge, whether replacement of the drum cartridge is necessary. The mode switch process switches a mode of a printing process between a normal printing mode and an extended printing mode. The normal printing mode allows the image-forming device to perform the printing process when the replacement of the drum cartridge is determined to be unnecessary. The extended printing mode allows the image-forming device to perform the printing process on a condition that the developing cartridge attached to the frame is not replaced with another developing cartridge in a state where the replacement of the developing cartridge is necessary.
