They were founded in 1980 and considering that then have great-tuned their goods to make sure dependability and excellent in each individual purchase.
Different types of HPLC columns are used in analysis of different pharmaceutical compounds Based on their character and column separation ability.
The selection to begin with acetonitrile is arbitrary—we could just as conveniently choose to start with methanol or with tetrahydrofuran.
This information provides an overview of C18 columns - the chemical Houses in the C18 practical team and the different types of C18 HPLC columns available.
Substantial number of processes and flow path configurations available to design your personal multi-move method.
HPLC is thus mainly a remarkably enhanced check here type of column liquid chromatography. Instead of a solvent staying allowed to drip through a column underneath gravity, it really is pressured by way of less than large pressures of as many as 400 atmospheres.
An HPLC normally consists of two columns: an analytical column, that's accountable for the separation, along with a guard column that's positioned ahead of the analytical column to protect it from contamination.
Remember to affirm you prefer to to obtain promoting and marketing electronic mail messages about Thermo Fisher Scientific services and products.
Ion-exchange: Separates billed analytes centered on their click here own ionic interaction With all the stationary section. Pick a cation-exchange or anion-exchange column based upon your analytes’ demand.
In liquid–liquid chromatography the stationary period is often a liquid film coated over a packing content, normally 3–ten μm porous silica particles. As the stationary stage can be partly soluble in the mobile stage, it could elute, or bleed from your column after some time.
