The mass method uses volumetric, density information and a calibration phantom of hydroxyapatite to calculate the actual mass of the calcified plaques [ 14].
AA concentrations were determined by the liquid chromatography-tandem mass spectrometric method using a 3200 Q TRAP triple-quadrupole linear ion trap mass spectrometer (Applied Biosystems, Darmstadt, Germany) and a high performance liquid chromatography system (Dionex, Sunnyvale, CA, USA) as described previously [ 13].
Denitrification rates were also measured using a mass balance method using water samples from multiport samplers.
The purpose of this study is to propose a mass estimation method using a Markov decision process and compare its performance with a method using an artificial neural network model proposed in a previous study.
For the analysis a simple and rapid quantitative and qualitative liquid chromatography tandem mass spectrometry method (using gradient elution) was developed with LODs ranging from 5 to 25 nM.
Brivanib concentrations were measured in glycinated plasma, after solid-phase extraction by a liquid chromatography/tandem mass spectrometry method using a stable-labelled internal standard of brivanib ([13C3,15N2]BMS-540215).
Plasma concentrations of afatinib were analyzed by a validated high-performance liquid chromatography tandem mass spectrometry method using [D6]afatinib as an internal standard.
The proteins were identified by the peptide-mass fingerprinting method using Mascot Search on the Web (Matrix Science, Ltd, London, UK).
Thus, we aimed to develop a mass-specific detection method using sensitive liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) for identifying 11C-labeled tracers and for verifying their specific radioactivities.
However, the frequencies obtained by the discretization methods are influenced significantly by the mass lumping method used.
