I have been used for UPLC-TOF MS Sunitinib 341031-54-7 and GC-TOF-MS. 2.5. GC-TOF-MS part of 300 l supernatant was having an insert into a GC Probengef transferred and dried under a stream of nitrogen. Thereafter, TMS was performed derivatization. The derivatization procedure was performed with minor Changes to our previous study reporting serum metabolomics. Briefly, 50 L methoxyamine to ensure as dry bottles and vortexed for 30 s. Methoxymation was performed at 30 stirred for 16 h. After adding a further 50 L BSTFA and vortex for 30 s, silylation at 70 was performed for 1 h. Each sample was derived from 1 liter in a gas chromatograph Agilent 6890 N mode with splitless injection time of flight mass spectrometry. The separation was on a DB 5ms capillary Molecules with helium as carrier Rier gas at a constant rate of 1.0 ml / min. The injector temperature was set at 270 . GC oven temperature was at 80 for the first two minutes, then programmed to ramp to 10 per minute at 180 , 5 per minute to 240 , 25 of minutes set up to 290 and conclude at 290 Lich held for nine minutes. Temperature of the transfer line temperature and ion source were set at 260 and 200 respectively. Mass spectra were obtained with Elektronensto Ionization in full scan mode. 2.6. TOF-MS UPLC survived Another part of 300 l was transferred into a sample bottle waiting UPLC TOF MS. A Acquity ultra-performance liquid chromatography with 10 cm 2.1 mm was charged 1.7 m BEH C18-S Molecules used in this study. The S Molecules
, constant at 50, was with a linear gradient of 5 to 50% B over 0 3 min, 50 70% B over 3 min 10, 70 min 100% B in 10 15 The eluted composition was at 100% B for 5 minutes, instead, where a water containing 0.1% ammonium formate and acetonitrile B. The flowsheets speed was 0.4 ml / min. The Silodosin 160970-54-7 injection volume was 2 L for the user positive ions and 4 respectively with the negative ion mode. The samples were run fosinopril controlled model The sandwich. All samples were stored at 4 w Stored during the analysis. Mass spectrometry data were collected using a Micromass LCT Premier XE. The scan range is 50 to 600 m / z with a cycle time of 0.2 s delay Gerung andinterscan 0.05 s at a 28 min analysis time. The source temperature was set at 120 with a gas stream c Only 50 L / h desolvation gas flow was set at 600 L / h at a temperature of 350 . The capillary voltage and the c Was presented at 2.3 kV for 40 volts. Mass spectrometry has been in W optics mode with 12,000 Aufl Powered solution with dynamic range expansion. Leucine enkephalin was defined as the mass of the latch in a concentration of 2 g / ml and the flowsheets rate of 20 l / min, with a frequency of 10 s lockspray. MassLynx software was used for the control and data acquisition. 2.7. Process data and statistical analysis The acquired MS files from GC-TOF-MS were exported in NetCDF format by software ChromaTOF. CDF files were extracted, with their own scripts, by Jonsson et al. MATLAB 7.0 for pretreatment processes such as data correction, noise reduction, eq TURES, orientation, distribution time windows, and multivariate curve resolution and high. The resulting three S Tze dimensions include information that the sample peak retention time and peak intensity Ten.
