Wide Application Of HPLC Columns
HPLC is more suitable for the separation and analysis of substances with the high boiling point, poor thermal stability, physiological activity, and relatively large molecular weight.
Hawach HPLC columns are widely used in the analysis of nucleic acid, peptide, lactones, polycyclic aromatic hydrocarbons, polymer, drugs, human metabolites, surface active agent, antioxidant, pesticides, herbicides analysis and so on. Its instrument structure and flow are various.
HPLC requires only that the sample can be made into a solution without gasification, so it is not limited by the volatility of the sample. According to statistics, about 20% of the known compounds can be analyzed by gas chromatography, and about 70-80% can be analyzed by liquid chromatography.
Since 1990, the rapid development of bioengineering and life science in the international and domestic, HPLC technology is proposed the more updated subject of separation, purification, preparation, such as the human genome project, proteomics and so on.
Column of HPLC
HPLC columns are the most important part, usually made of thick-walled glass tubes or stainless steel tubes with polished inner walls. Copper, aluminum, or Teflon tubes are available for corrosive samples requiring high-pressure resistance.
