Over the past ten years, high performance liquid chromatography has supplanted many spectroscopic 
techniques and gas chromatography in the quantitative and qualitative analysis of pre-sale procedures, 
drug marketing, and their control. Although it was once believed that HPLC would be a 
complementary technique to gas chromatography, it has now almost entirely supplanted gas 
chromatography in pharmaceutical analysis. When compared to other methods, the use of a liquid 
mobile phase, which allows for the transformation of mobilized polarity during chromatography and 
other mobile phase modifications based on the properties of the substance being tested, is a significant 
advantage in the separation process.The next factor that makes good separation possible is the broader 
choice of stationary phase.
