With ChromAssist, we have enhanced the guidance features for analytical operations with a user orientation in pursuit of user-friendliness (even for ¬first-time users) to enable simple execution of each analytical task.

Reduces the complexity of analytical work
We have focused on making it easier for users to fully master the proper implementation of HPLC. To this end, we have enhanced the assistance features to reduce the time spent for routine performance con¬firmation as well as complex maintenance and troubleshooting regarding analytical work.

Friendly graphical user interface (GUI)

Operations can be performed using an intuitive screen with each parameter represented by an image.

Enhanced navigation and guidance features

Loaded with guidance features and enhanced help features to support the overall analytical workflow, from starting up the device through testing, analysis, maintenance, and troubleshooting. There is no longer a need to refer to a manual. Intuitive tutorials have been prepared for fi¬rst time users.
Recording analytical procedures as routine analyses, making repeated measurements easier. Furthermore, the guidance features include content for different purposes, such as LC and MS basic lectures, maintenance videos, and troubleshooting.
These can be conveniently viewed during the measurement.

Display of the analysis log can be used to assess system stability

To obtain accurate analytical results, it is important to fully ensure device and system performance, including the column. Degradation of the column and variations in detection sensitivity can be easily determined by recording a summary of the theoretical number of plates, the resolution, and the reproducibility (SD, RSD). In addition, by setting RT window for results, assessment comments (Pass/Fail) can be noted, and the stability of the system can be assessed on a daily basis.

System performance check

Data acquired for each analysis can be checked for quality. System Suitability Test (SST) reports conforming to the Japanese, US, and European Pharmacopeias (JP, USP, and EP) and operation check results that classify the operating conditions for each HPLC module can be summarized in a report.

System suitability test report

This is useful for evaluating the overall analysis system. In addition, degradation of the column and other components can be evaluated by checking the theoretical number of plates each day.

Daily maintenance support

To ensure that each HPLC module is in good condition, it is important to monitor and manage consumable parts. Part replacement dates, usage history (liquid feed amount, number of uses, cumulative time, etc.), and guidelines for recommended replacement can be recorded and checked to monitor the condition of consumables. This information can be output as a report or stored in a log. In addition, when it is time to replace a consumable, the Assist feature provides visual support through maintenance videos.

Troubleshooting support

We have published a collection of specific troubleshooting examples in a guide and we provide support to resolve problems such as abnormal analytical results. These examples reflect the experiences of both Hitachi and Hitachi users collected over many years.
