  • In this post, I will share some tips on how to develop a reversed-phase flash purification method using HPLC. (biotage.com)
  • Now that you know the reasoning behind why method development on HPLC for reversed-phase flash chromatography is preferred, I need to explain how to do the conversion. (biotage.com)
  • Simply put, the process is to create a gradient on an HPLC system and then to duplicate it on a flash system. (biotage.com)
  • Using an off-the-shelf, commercially available HPLC column will certainly point you in the right direction regarding the gradient method but due to media particle size and potential selectivity differences, the results may not translate as well to flash as you might want. (biotage.com)

  • Flash Column chromatography is a form of liquid chromatography that uses a solvent coupled with a pressurized gas like nitrogen in order to aid in the separation process . (extraktlab.com)
  • Column chromatography is separated into two categories, depending on how the solvent flows down the column. (ijpsr.com)
  • If the solvent is allowed to flow down the column by gravity, or percolation, it is called gravity column chromatography. (ijpsr.com)
  • If the solvent is forced down the column by positive air pressure, it is called flash chromatography, a "state of the art" method currently used in organic chemistry research laboratories 1 . (ijpsr.com)
  • In flash chromatography however air pressure is used to speed up the flow of solvent, dramatically decreasing the time needed to purify the sample, therefore making the column and running the separation could take less than 10-15 minutes. (ijpsr.com)
  • Flash chromatography differs from the conventional technique in two ways: first, slightly smaller silica gel particles (250-400 mesh) are used, and second, due to restricted flow of solvent caused by the small gel particles, pressurized gas ( ca. 10-15 psi) is used to drive the solvent through the column of stationary phase. (ijpsr.com)
