UHPLC Instrumentation for Nano, Capillary and Micro LCThis calculated sensitivity increase is actually a scale factor between the conventional and miniaturized LC application, with flow rate as the best example. Typically, the flow rate in conventional LC(4.6 mm i.d.) is 1000-1200 µL/min ...
Why do elastomers have no glass transition temperature? Why do lenses have two focal points? Why do some pigments travel further in chromatography? Why was the Antarctic Treaty created? Why is distillation a purifying technique? Why does water form droplets?
Why is it important to do multiple trials of a titration instead of only one trial? Why is titration a good method? For titration, why is the Mohr method better than the Fajans method? Explain. Why can't we use gas chromatography to analyze the sample of Steroids?

摘要: Whenever we go online, we might find ourselves part of an experiment - without knowing it. Digital platforms track what users do and how they respond to features. Increasingly, these tests are having real-world consequences for its participants.关键词:...
How the Leaf Science Experiment Works: Chromatography!To find all these hidden pigments in your leaves, you’ll use chromatography. Chromatography separates a mixture by moving them across a different substance that is standing still. In this experiment, we’re moving the plant pigments that have ...

How do you divide chromatography? Why is important to determine both the absorption spectrum and the action spectrum? Explain isolation precautions and discuss different types of isolation precautions and equipments used? Why are the tropics so diverse? Explain the basic principle of spectrophotometry. ...
Why do we use a drying agent to remove the water before evaporating the solvent on the rotovap? Why can't we use gas chromatography to analyze the sample of Steroids? Why does the dye and unknown spots must be above the level of the mobile phase when starting the chromatography? What...
