Sentence examples for preparative experiment from inspiring English sources
A preparative experiment was carried out with initial concentration of the dye 500 µM and 0.11 M NaCl as a supporting electrolyte at a constant applied current density of 34.96 mAcm−2 and initial pH 3.9.
In a preparative experiment, NCC 1 (192.9 mg) was adsorbed on silica gel 60 (19.3 g).
In a preparative experiment, a solution of Mc-FCC-56 (31 μmol; containing about 30%% of its isomer, Mc-FCC-53) in aqueous citric acid (0.02 m) was stored for 159 h under an argon atmosphere in the dark at 15 °C.
Preparative experiments led after alkylation to the formation of N-methyl-hydrazobenzene and N,N′-dimethylhydrazobenzene.
Preparative experiments using calorimeter, Mach probe and high-speed camera have been started at the end-mirror region and the heat flux density of the level in 1 10 MW m−2 was achieved in standard hot-ion mode plasma-confining experiments, which gives a clear prospect of generating the required heat flux density for divertor studies.
Similarly, in preparative experiments where mixing is considerably slower than in the stopped-flow chamber, the same proton-transfer chemistry can occur.
The most likely explanation, which was supported by DFT computations, was that at the temperature of the preparative experiments (∼100 K higher than the EPR study) the spiro-cyclization became reversible whereas the 6- ortho-process did not.
After 1y of in situ growth, 88 fragments of experimental set 1 (73.3%) and 48 (66.7%) preparative of experiment 2, developed colonies of different shapes.
In a similar preparative HPLC experiment semipure compound 2 appeared at 16 min to give 12 mg pure compound.
About 2.7 μmol of 4 epi could be re-isolated in this way, as well as about 10.7 μmol (55%%) of the more polar NCCs 6 epi and 5 epi, and (smaller amounts of) YCC 7. The fraction with a retention time of 50 min in the preparative HPLC experiment (containing 6 epi ) was reduced to 10 mL using a rotary evaporator, diluted 1 1 (v/v) with 50 m m aq.
Further studies of preparative electrolysis experiments by constant current electrolysis were carried out.
