As one example, results of quantitative MALDI-MSI can be matched to UHPLC-TQ-ESI-MS measurements performed on the same tissue. However, cross platform comparisons are affected by differences in the physical and chemical parameters of the samples, and may be aided by normalization approaches. ...
By this way, the device could nebulize the drug solutions into the simulated exhaled breath containing illicit drugs at different levels, and the collection unit with electret material could adsorb drugs in the sampled SHEBA for HPLC-TQ-MS/MS detection. Thus, this study aimed to develop, ...

A simultaneous quantitative method for analysis of the 22 identified compounds was established using UHPLC coupled with a triple-quadrupole tandem mass spectrometer (UHPLC-TQ-MS/MS) in multiple reaction monitoring mode. The established method was validated in terms of linearity (R2, 0.9990–0.9996)...
