1)To ues reverse phase chromatography solvents like:-Acetonitrile,Methanol in HPLC Grade
2) To use normal phase chromatography sovents like:-Iso propyl alcohol,n-Haxane HPLC Grade

Why reverse phase chromatography is so called?
The first chromatography used was with polar stationary phase and non polar mobile phase, called normal phase. So, later when this was reversed by using polar mobile phase and non polar stationary phase was called reversed phase. Although reversed phase implies that it is less used, it is not the case. RPLC rose to success around the 1970s as NPLC dropped off.
In what phase the reverse of prophase?

What is mobile and stationary phase in Chromatography?
Moblie phase is that phase in chromatography that moves the analyte components along with it. Stationary phase remains static during chromatography.
What is normal and reverse chromatography?
normal chromatography based on polarity and non polarity principle If mobile phase is polar, compound is non polar,then non polar compound first elutes as peak and then followed by polar compound reverse chromatography is if the mobile phase is polar, the polar compound first elutes and then followed by non polar compound
What is the H.P.L.C. chromatography?
HPLC stands for high performance liquid chromatography. It is a liquid chromatography which involves the separation of the compounds on the basis of their polarity. It is used to analyze, identify, purify & quantify the compounds.

What has the author Shahab A Shamsi written?
Shahab A Shamsi has written: 'Reversed phase /ion chromatography and capillary electrophoresis of ionic compounds with indirect detection' -- subject(s): Chemistry, Ion exchange chromatography, Capillary electrophoresis

What difference between dad and uv detector in hplc?
Liquid chromatography (LC) encompasses all chromatographic techniques using liquid mobile phase, including planar chromatography (paper chromatography and thin-layer chromatography) and column chromatography (classical column chromatography, and high-performance liquid chromatography on packed and capillary columns). The term liquid chromatography is nowadays often used as a sinonim for high performance liquid chromatography (HPLC) and ultra-high performance liquid chromatography (UHPLC).
What are the principles and methods of high performance liquid chromatography and gel chromatography?
Liquid chromatography separation of multicomponant system according to diffrent interaction of dissolved componant with stationary phase. the stationary phase and mobile phase is very wide range
Why is a phase change only a physical change?
See "Related Questions". Phase changes are reversible by adding or subtracting heat. In many cases chemical changes are not easily reversed.
What is the difference between partition chromatography and adsorption chromatography?
The partition chromatography involves separation between liquids while adsoption chromatography involves solid and liquid separations. Answer: Partition Chromatography is a liquid liquid extraction which involves two solvents while adsorption chromatography is a liquid solid extraction which involves a solid stationary phase & a liquid mobile phase.
What is descending paper chromatography?
ascending chromatography is a type of chromatography in which chromatic substance is in mobile phase and moving from bottom to top. similarly in descending chromatography mobile phase moving from top to bottom.
What is the difference between reverse phase and normal phase chromatography?
Normal Phase: It has a polar stationary phase and a non-polar mobile phase.Reverse Phase: It has a non-polar stationary phase and a moderately polar mobile phase
