Peak Widths in MassHunter Qual for LC-MS data

I am using Masshunter Qual (version 6 and version 7)


In the integration peak list there is more than one value of width listed. There is width and FWHM. It is not clear how they differ as the information I can find suggests that both are half-width. They do differ though as often the values listed are numerically different. I need these values as we are manually calculating resolution for some of our classes.

In addition I have been noticing that sometimes the values are listed as 0. This doesn't make sense. I am assuming that this is a display error in terms of not sufficient digits being used to display the width. Is there a way to change this in Qual?



Thanks in advance
