column chromatography उदाहरण वाक्य

उदाहरण वाक्य

1. A majority of the reports demonstrated the processes of purifying the as-synthesized CQDs fragments via post-treatment such as filtration, centrifugation, column chromatography and gel-electrophoresis.
2. Because the column chromatography has a constant flow of eluted solution passing through the detector at varying concentrations, the detector must plot the concentration of the eluted sample over a course of time.
3. Most commercial 99 Mo / 99m Tc generators use column chromatography, in which 99 Mo in the form of water-soluble molybdate, MoO 4 2 " is sodium salt of the pertechnetate.
4. The key step in the synthesis was the cyclization of ring C : "'16 "'was treated with SmI 2 to yield totarane diastereomers which were separated by column chromatography.
5. Thermally initiated, conrotatory opening of the benzocyclobutene generated the o-quinodimethane, which reacted intermolecularly to give the tetracycline skeleton; the diastereomer shown was then crystallized from methanol after purification by column chromatography.
6. Most commercial 99 Mo / 99m Tc generators use column chromatography, in which 99 Mo in the form of molybdate, MoO 4 2 " is adsorbed onto acid alumina ( Al 2 O 3 ).
7. In effect this configuration is similar to that used for column chromatography as the extent of reduction increases to 100 % as the solution passes down the tube and the product is completely separated from the starting material.
8. For a non high-temperature alternative, perhaps " dissolve " ( or crush ) the sodium in a non-reactive organic solvent and pass it through a sand column chromatography mixture, and collect the appropriate eluent?
9. The material was dried for one day, ground to a powder and 5 grams were refluxed in methanol for 4 months to yield 2.5 mg ( 0.049 % ) of cavicularin after column chromatography and preparative TLC.
10. Once the plant samples were separated using adsorption chromatography and column chromatography, they were analyzed via mass spectrometry, IR spectroscopy, UV spectroscopy, and gas chromatography, 31-and-34-carbon-long alkane chains were found to be present in the hexane layer of the adsorption chromatography
