What is the difference between vacuum chromatography and flash chromatography?
Flash chromatography uses pressure (under 10 psi) to pump solvent down a column at a rate faster than gravity would provide. Vacuum chromatography uses a vacuum at the bottom of the column to pull solvent through. Both can be performed with standard glass columns, but usually vacuum chromatography is done with a silica filled vacuum funnel instead as a rough purification technique.
How is chromatography a analytical tool?
Chromatography is an analytical tool used to separate and analyze complex mixtures. It works based on the principle that different components in a mixture will move at different rates through a stationary phase when subjected to a mobile phase. By analyzing the resulting separation pattern, chromatography can provide valuable information about the composition and identity of the mixture being analyzed.
What is the function of the blue filter in a compound microscope?
Blue wavelengths provide better resolution.
What is the primary use of slants?
They are used to culture microorganisms and provide greater surface area for the growth of colonies.
The folds of the inner sac provide what?
Folds increase surface area and therefore a greater surface area for gas exchange
What are the change involved when view the prepared slide under microscope using different objective lens?
it has to do with the resolution of the image of the slide obtained...the larger the objective lens value is the greater the resolution it will provide, greater the resolution higher the details.

Where can I find conflict resolution lessons in my area?
A local college or university might provide conflict resolution lessons or classes in your area. Another way to find out about conflict resolution lessons is to explore various sites on the world wide web that provide these, such as the following: www.universalclass.com/i/crn/30043.htm, www.all-things-conflict-resolution-and-adr.com/Jobs-In-Conflict-Resolution-Lessons-From-the-Front-Lines.html, and www.teaching-strategies-for-classroom-discipline.com/conflict-resolution-activities.html.
What is is the resolution of sounder?
The resolution of a sounder is the smallest detectable change in a measured value. It represents the level of detail or accuracy that the sounder can provide in its measurements.
