Why do scientists use infrared telescopes? Why is optical pumping not used in a gas laser? Why are molecular clocks important in the construction of cladograms? Why is an inverted microscope used for cell culture? Why was the Murray-Darling Basin plan created?
What is the best experimental procedure to use in choosing an eluting solvent for column chromatography? Describe the process of chromatography and how it is used by scientists. Why would mixed solvents be used for recrystallization? Why should latex gloves be worn when preparing chromatography p...

Optimization of homogeneity and solubility To remove protein aggregates, it is important to ensure that the last step of the purification process always is size- exclusion chromatography. A column should be chosen that allows elution of the protein of interest well away from the void volume, and...
40 August / September 2013 Why do I have Carryover? by Chromatography Today Help Desk Within the field of quantification one of the biggest limitations of an analytical procedure is the dynamic range of the assay. Some of the challenges associated with this statement will be addressed and ...
Why do many scientists think that total phosphorus concentrations are more useful indicators of nutrient supply than dissolved phosphate concentrations? In a vacuum the coloured particles of potassium manganate(vii) would move very quickly in water. Why wo...
Proteins are the functional agents that make biology go, and they are also functional tools that scientists need to do biological research. In a way, this is analogous to "compil- ing" a software program. The important difference to software, however, is that once "compiled," proteins are ...
