VMN neuron and astrocyte amino acid LC–ESI–MS analysis Pre-column sample derivatization, uHPLC column and internal standard selection, and optimized mass spectrometric gas and temperature parameter settings were implemented as previously described21. For each treatment group, cell lysate aliquots from ...
The system consists of a robot integrated with programmable high performance liquid chromatography (HPLC) equipment and a laboratory computer, and it allows the automation of sample preparation, HPLC analysis, and report generation. It also selects the HPLC column and the mobile phase through the ...

Column lengths can be reduced by a factor of three over the use of 5 µm media. The system is engineered to handle the increases in backpressure that accompany the step down in separations particle size and the step up in flow rates. ...
column effluent (aerosol) enters the straight drift tube, allowing the mobile phase to evaporate in it. In mode B, the aerosol is passed through an elbow tube, where large particles are deposited and flow into the exhaust gas. Tube, the remaining small particles enter the spiral drift tube....
Xcalibur software (version 3.0) was applied to command instruments, gather and analyze data. Thermo Scientific Accucore™ C18 column (100 × 3 mm, 2.6 μm, Thermo Scientific) was employed at column temperature 30 °C. The mobile phase consisted of 0.1% formic acid in water (A) and ...
