Resolving Power & Parts Per Million

13057_rp.gif (18546 bytes)

This program allows you to quickly and easily calculate and compare:

  • Resolving Power
  • Mass Difference in u or mmu
  • Mass Difference as parts per million (ppm)

for any pair of m/z values.

You can vary any parameter and view how it interacts with other parameters. For example, you can see how much resolving power is required to separate two masses that differ by 10 mmu, or you can determine how many ppm correspond to a specified mmu value.
