Zhang X, Lin Z, Fang J, Liu M, Niu Y, Chen S,et al. An on-line high-performance liquid chromatography–diode-array detector–electrospray ionization–ion-trap–time-of-flight–mass spectrometry–total antioxidant capacity detection system applying two antioxidant methods for activity evaluation of...
The PM detector was used to measure the air outlet side to calculate the filtration efficiency of the composite sponge. At the same time, the pressure drop detector was used to monitor the pressure drop on the front and rear sides of the composite sponge. As shown in Fig. 5(a), the ...
Detector: SPD– M 20 A (Diode array detector) Column: LC– GC Qualisil BDS C18 Dimensions: (250 mm × 4.6 mm, 5 μm) Mobile-phase: methanol: (0.2% v/v) OPA, (80:20 v/v) Mode: Isocratic Flow rate: 1.0 mL min−1 Temperature: Ambient temperature Detection wavelength: 260 nm ...
mAU is the detector response in millivolts as arbitrary units. Panel (B): the purity plots of the peaks in the chromatogram presented in Panel (A). The red, blue, and black curves are the threshold (zero) lines, peaks, and purity curves, respectively. Table 2. Peak purity profiling ...
Using the fast and validated ultra performance liquid chromatography-photodiode detector-quadrupole/time of flight-mass spectrometry (UPLC-PDA-Q/TOF-MS) method, we confirm the presence of the following compounds: phenolic acids, flavonols, flavan-3-ols and hydrolisable tannins (gallotannins and ...
The system is equipped with a (ISO-3100SD) pump, (WPS 3000 SL) autosampler, (TCC-3000SD) column thermostat and (DAD-3000 RS) diode array detector (Germering, Germany). The software used was Chromeleon 6.8 (Germering; Germany). A column of Hypersil Gold was used with a 5 μm ...
compounds during preliminary experiments, but also during the analysis of the optimized extracts produced in the frame of experimental design, a Shimadzu HPLC 2030C prominence-i system was used, equipped with a binary pump, a degasser, an autosampler, a column heater, and a PDA detector. A...
to a ToF mass analyzer the solvent flow should be less than 0.5 mL per minute and the amount of acid should be very low, since more than 0.1% of trifluoracetic (TFA) or formic acid in the solvent system as currently used in HPLC coupled to PDA detectors can damage the ToF detector....
2.2. UHPLC Equipment UHPLC analyses were carried out on an Agilent 1290 Infinity chromatograph (Agilent Technologies, Santa Clara, CA, USA) equipped with a photodiode array detector (PDA), thermostat and autosampler. The column used in the separation was Zorbax Eclipse XDB-C18 column (1.8 µ...
