Running the Sample


This page is under construction!


NAME THE EXPERIMENT:

In the Xwinnmr program, click on the 'File' menu and choose 'New'. In the 'NAME' field, type in a unique name for the sample. If you are running multiple experiments on the same sample, you can use the same sample name and increment the 'EXPNO' field. Click 'OK' to continue. The screen will display 'New Data File'. Note that if you start the experiment by typing 'zg' at the command prompt, Xwinnmr asks if you wish to over-write the existing experiment.

CHECK EXPERIMENTAL PARAMETERS:

At the Xwinnmr command line, type 'ased' to display the current pulse program and experimental parameters. Verify that they are correct for your experiment. Experimental parameters will be chosen by your laboratory instructor and will generally not require adjustment. Close the dialog box.

START DATA ACQUISITION:

At the Xwinnmr command line, type 'zg' and press enter to start the run. The FID will be displayed and updated as the acquisition progresses. If necessary, you can resize the FID by clicking and holding on the resize button (both up and down arrows) and moving the mouse vertically.

END DATA ACQUISITION:

When the experiment is complete, 'checklockshift finished' will be displayed below the Xwinnmr command line.
