:???ɂ??Ǭ?Ǭ???Ǭ?Ǩ??ɂ?ɬ??Ǭ?Ǭ???ɂ?Ǩ??ɂ?ɬ?This [mass-to-charge] unit would be defined as the quotient of mass in units of u and the number of charges, z. The number of charges could be positive or netagive, depending on the sign of the charge ???ɂ??Ǭ?Ǭ???Ǭ?Ǩ??ɂ?ɬ??Ǭ?Ǭ???ɂİ?Ǭ?Ǭ? Using the standard rules for abbreviation, we have 1 Th = 1 u/atomic charge. For example, the peptide [sic] myoglobin myoglobin (isotope average molecular weight 16,950 u) can be deduced from the measurement of a peak at 998.0 Th provided it is known that the ion bears 17 charges.???ɂ??Ǭ?Ǭ???Ǭ?Ǩ??ɂ?ɬ??Ǭ?Ǭ???ɂİ?Ǭ?ɬ? | |||
