High Sensitivity and Extended Linear Range Quantification of Inhalation Drugs in Dried Blood

In this technical note, the authors demonstrate the quantification of Budesonide in dried blood spots with a very sensitive LOQ of 5pg/mL using the QTRAP 5500 system, and successful extension of assay linear range by five-fold using the SignalFinder Algorithm in MulitQuant^TM Softward 2.0.
