Classification: CPC G  H | IPC G  H

Claim 13:
14. The method of claim 13, wherein the linear ion trap includes a charge detection cylinder,
and wherein the lipoprotein ion oscillates back and forth in the linear ion trap each time passing through the charge detection cylinder,
and wherein the charge of the lipoprotein ion is measured based on a charge induced by the lipoprotein ion on the charge detection cylinder each of multiple times the lipoprotein ion passes through the charge detection cylinder,
and wherein the mass-to-charge ratio of the lipoprotein ion is measured based on a time period spent by the lipoprotein ion each of the multiple times the lipoprotein ion passes through the charge detection cylinder or a fundamental frequency of oscillation of the lipoprotein ion back and forth through the charge detection cylinder.
