A high-performance liquid chromatographic technique for the simultaneous determination of prednisolone and prednisone in human plasma, whole blood, urine, and bound-to-plasma proteins, using betamethasone as internal standard, is presented. Liquid-liquid extraction is used for whole blood samples, and solid phase extraction is used for plasma, urine, and proteins bound to plasma. The accuracy, ...

Imaging samples on a surface by mass spectrometry (MS) requires the combination of MS detection with a scanning mode that enables localized desorption and ionization and/or detection of sample analytes with good spatial resolution. We have developed a new mass spectrometry imaging (MSI) method based on electrostatic spray ionization. It works under ambient conditions and can be applied to a wid...
