Creating a Method
ChemStation will select all masses (2-260 AMU) excluding masses 14, 16 to 19, 32,
36, 38, 40, and 41 AMU. You can tell that the masses are selected by the green
vertical bars above the points on the mass scale.
You can select a range of masses by dragging the mass scale with the mouse, using
the left button. You can deselect a range of masses by dragging the mass scale with
the mouse, using the right button.
Masses that have high continuous background count rates, such as 14, 16 to 19, 32,
36, 38, 40, and 41 are automatically skipped since scanning these masses would
damage the detector.
ChemStation returns to Spectrum Acquisition Parameters dialog box. You can see
the masses selected on this screen as well.
ChemStation will display which 6 points in a peak it will scan. The width of each
bar is 0.05 AMU.
box.
Input the integration time e.g. 0.10 (sec), and then click Enter. ChemStation will
automatically calculate and show the integration time per mass in seconds, inside
the Integration Time box.
and click Enter.
ChemStation will automatically calculate the acquisition time and show how much
time it will take to acquire data using this method in seconds, inside the Acquisition
Time box above the repetition.
Clicking Check Parameters is just to make sure you haven't made any major errors,
such as not selecting some of the isotopes to be acquired, etc. If there are no errors, a
dialog box will pop up indicating there is no error in the method. If there are errors,
some description telling you what the mistake is, will pop up. Click OK on the pop
