Introduction
This document outlines the procedure for creating a pressure recorder to a method in MagIC Net. Adding a pressure recorder to the method will provide valuable information regarding the system for issues such as low pressure, pressure drops or pressure increases. A pressure variation of 0.5MPa is deemed acceptable.
Instructions
-
Open MagIC Net, go to Method program and open the method by clicking File → Open.
-
In the Devices sub-window, click Edit → Add → Analysis. Name this analysis Pressure.
-
Select the Pressure analysis and next to the Data source box, click the [...] button. Select the IC → Pump → System Pressure → Click OK.
- Leave the injection valve, Pump, and Column as "not defined". Uncheck Maximum Flow and Maximum Pressure below the monitoring options.
-
In the Data Acquisition tab, make sure to set the same recording time as the main analysis.
- In the time program, add a Start Data acquisition command next to every Start Data acquisition command for the main analysis (it's possible that it may be in several subprograms, depending on the method).
-
Click Edit → New → Select Pressure → Start Data Acquisition → OK. Time will be the same as the main data acquisition command. Screen shots can be found below.
-
Save the method (File → Save) and run an analysis to verify that the system is recording pressure. In the database (after a run), click on the determination and check the "Pressure" tab in the curves sub-window. See the screen shot below.
