. rates are applied. For example, optimum flow rate of 1.0mL/min may be employed for a 4.6-mm-i.d. column. A 2.1-mm-i.d. column has optimum flow rate of 0.2 mL/min. For LC/ESI-MS, ESI-MS is compatible. excellent tools for structural characterization of complex molecules. A third type of MS/MS instruments is a hybrid of tandem-in-space and tandem-in-time devices, including the Q-trap (QQ-2D-linear t...

. atoms in a structure can provide additional information for struc- tural characterization, such as the differentiation between N- or S-oxide for- mation and hydroxylation in drug metabolism studies.. calibration can provide an order-of-magnitude greater mass accuracy than external calibration for the FT-MS analysis. One example is the high-resolution ESI-FT-ICR MS analysis of a mixture of. 14....
