Preprative HPLC Demo By Analytical Technologies Limited Preparative HPLC Preparative high pressure chromatography has no essential difference with traditionally classical column chromatography. It has higher efficiency and achieves automatic operation. About the instrument, a high pressure pump is adopted to deliver mobile phase. At the same time, a detector is connected to the outlet of the column which can detect the fraction on-line constantly.
The preparative high pressure chromatography has several features as following:
1.shortter column length;
2. larger column ID;
3. higher flow rate.
Sometimes it is also called High performance preparative liquid chromatography
