Creating an Instrument Control Method 141 GLP This section, only available with Knauer networking pumps, displays GLP (Good Laboratory Practice) related information transferred to or “downloaded” from the pump. Pressing the -button will actualize this information. The extent of the information depends on the given pump. Direct Control The direct control area will appear disabled as long as the direct control option is not activated. Except during a run it can be activated via the menu sequence METHOD – OPTIONS – RUNTIME SETTINGS…, (see Fig. 249 on page 170). The direct control enables someone to control the instrument directly, even during a running method. Changes made to the settings and applied during a run will be automatically stored in the method. The corresponding new lines in the spreadsheets are marked with the comment DC Op (Direct Control Operation). Applied changes in a not- running method will not be saved. However, it will be recorded in the Activity Log. Flow (ml/min) Specify the flow in ml/min you would like to have at the moment and click the button to send the flow to the pump. If an LPG pump is used, also the gradient setting will be send. The Flow Apply button will send the flow, entered into the Flow field, to the pump. The button will interrupt delivery while the run time continues. The pump remains in slave mode. This button is also active during a run to stop the pump e.g. in an emergency situation. This will not stop the whole method, only the pump’s flow! Due to, that this is a method change; the current method will be changed. The Stop will be added to the currently running method, if the option “Save changes in time table” of the “Direct control during a run” section of the Runtime Settings is enabled. Please refer the section “Runtime Settings” in the “Knauer Instrument Control Options” for more information. Pressing this button will send the current flow and gradient settings for execution to the pump. Gradient Components (%) Specify the composition (% A, B …), you would like to have at the moment and click the button. The components field is applicable for the HPG (High Pressure Gradient) or LPG (Low Pressure Gradient) mode. Depending on how many components are configured, the corresponding number of fields (% A, B …) will be accessible. The button is active only during a run. Clicking on it opens the following window.
142 Creating an Instrument Control Method Fig. 209 Gradient modify window In the gradient spread sheet the elapsed lines are grayed. The red line shows the actual gradient status. The yellow ones are that which are open for modifying. The Gradient Modify allows for changing the gradient table by adding new lines of freezing the gradient for a defined time. To modify the gradient program, enter the time for the new line and the desired values in the fields on the top of the window. To change an already existing time line, enter this time in the “Time” field and the new values. Clicks on insert the new or modified line into the gradient program. The changes by one or more committed lines becomes only active (send for execution to the pump) by a mouse-click on the button . You will see then the new line(s) in the gradient spread sheet. Due to that the complete gradient in the pump will be replaced with a new one, the run time on the pump’s display will start with time 0.00 min. This will not touch the method run time. Fig. 210 Gradient table modify window To delete any line of the gradient program, enter the time of the line to be deleted and press the and then the button. You can also freeze the current gradient status for a time you have entered by pressing the button. Fig. 211 Gradient modify window freeze gradient This will extend the pump table and therefore also the pump’s run time. In the following example the gradient (100% A / 0% B – 0% A / 100% B in 10 minutes) will be freeze for 2 minutes (from 3.34 – 5.34 minutes: at 3.34 minutes the freeze-command was sent). The gradient freeze will be sent and executed, if you click on the -button.
