Software workstation
1. The wizard-style operation interface supports standard operating procedures and method libraries, making it easier for users to manage methods. Independent method optimization interface, adjust method parameters to improve test results, and clear operation process
2. Three-level authority management and audit tracking, complying with GLP regulatory requirements.
3. The test data is displayed in real time during the test process. The original test data of the sample is also saved in the project file and can be viewed and exported to facilitate user traceback of results. The test process and result data can be displayed in custom data formats to facilitate user observation, and import and export data in standard formats.
4. Support common testing methods, including flame method, flame emission method, graphite furnace method, hydride generation method, etc.
5. Support standard curve method and standard addition method. Automatically fit the standard curve, and automatically update the standard curve and test data when the data changes
6. Built-in performance verification program, the results can be saved as project files to facilitate management of instrument status
Safety protection
1. Acetylene leakage protection system: 24-hour detection of acetylene concentration inside the instrument and in the working environment. Once the acetylene exceeds the warning concentration, the acetylene gas line will automatically close immediately and prompt an alarm.
2. Real-time flame monitoring: The flame monitor monitors changes in the flame at any time. When an unexpected power outage or incorrect operation causes the flame to go out, the acetylene gas line will automatically close immediately and prompt an alarm.
3. Graphite furnace protection: Monitor the protective gas pressure and cooling water flow at the same time. If there is abnormal fluctuation, the heating will be stopped immediately and an alarm will be prompted.
4. Position identification: and drainage liquid level detection to ensure all-round protection for operators when flames are burning.
