Study TitleAnalysis of Dried Blood Spots by Paper Spray Ionization - MS
Study TypeAnalysis of Dried Blood Spots by Paper Spray Ionization - MS
Study SummaryConcentrations of cocaine (6, 5,3,2,1.5,1,0.75,0.5,0.25,0.125, 0.062, and 0.031 ppm) were spiked into whole human blood for PS-MS analysis. A 10 uL volume of blood/analyte mixture was allowed to dry on Whatman Grade 2 filter paper. A 1ppm concentration Cocaine-d3 was used as an internal standard. Parameters of the paper spray system were optimized, including spray voltage, capillary temperature and solvent. The internal standard was added on top of the dried blood spot sample. Wide isolation tandem MS was used to generate a calibration curve.

Project Title:Direct Analysis of Dried Blood Spots by Mass Spectrometry
Project Type:Direct analysis methods, dried blood spots, MALDI, paper spray
Project Summary:The direct analysis methods of MALDI and paper spray ionization mass spectrometry were used to analyze dried blood spots without the need for punching out or extracting the samples. Ionization and instrument parameters were optimized, and a quantification method was developed for both techniques utilizing internal standards and a wide isolation mass window. Additionally, the continuous addition of solvent to the paper spray ionization setup was explored, as well as the use of a solvent gradient for potential sample clean-up.
