Why acetonitrile is used for the calibration of hplc?

In the laboratory, acetonitrile is used as a medium-polarity solvent that is miscible with water and has a convenient liquid range. With a dipole moment of 3.84 D, acetonitril

What detectors are used in HPLC?

The detector for an HPLC is the component that emits a response due to the eluting sample compound and subsequently signals a peak on the chromatogram. It is positioned immedi

Why caffeine is used in hplc calibration?

Caffeine having different wavelents it having 2 maximas  and 1 minima.  1st maxima is 205nm  2nd maxima is 273nm  minima is 245nm  and it is primary reference standa

Why caffeine is used for calibration of HPLC?

Caffeine responds in 3 wavelength regions i.e 196 - 208nm in which caffeine maxima at 203±2nm 240 - 248nm in which caffeine minima at 244±2nm 270 - 278nm in which caffeine m

How do you use hplc?

  This is a difficult question to answer because there are so many uses for the HPLC. The HPLC is widely used to separate a complex mixture into individual compounds. Sc

Why internal standard you used in hplc method?

Internal standard can be used for calibration by plotting the ratio of the analyte signal to the internal standard signal as a function of the analyte concentration of the sta

What is hplc?

high performance liquid chromatography. Generally the stationary phase in HPLC is known as reversed phase as the stationary phase is non-polar while the mobile phase is polar.

What are the columns used in hplc?

large columns, specifically for packing.  * analytical columns, for quantitative analysis, usually accompanied by a UV-vis detector.  * Narrow bore columns, for more sensiti
