Our columns satisfy superior design and style criteria, thus making sure performance and scalability. DAC technologies allows reproducibility and robustness after some time.
Column alternative isn’t almost speed and solvent consumption – Even though both of these factors do need to be taken under consideration for practicality and value.
They ended up Established in 1980 and due to the fact then have wonderful-tuned their products and solutions to guarantee dependability and high quality in every buy.
Bonded hydrocarbons like C8 and C18 as well as other non-polar hydrocarbons are used as stationary section in reverse section columns while aqueous natural Alternative like water-methanol or water-acetonitrile combination is used as mobile stage.
The level of retardation largely is determined by the character of your analyte along with the composition of both stationary and mobile phases.
Therefore silica columns can be used to research the compounds of different chemical natures. The material stuffed from the HPLC columns is referred to as a stationary section.
Among these detectors, one of the most affordable and common procedures are UV and refractive index (RI) detectors. They have got alternatively wide selectivity fair detection restrictions more often than not. The RI detector was the primary detector readily available for business use.
It really works on the theory of hydrophobic interactions; consequently the more nonpolar the material is, the lengthier It will probably be retained.
According to the variation of stationary phase and mobile stage, we can easily be divided them into down below four different types that usually used.
With regards to the lab and the person functioning the tests, some labs may only have a single of these HPLC column types, while some can have all of these. Each individual lab should have at the least a person pack of every of the different HPLC column types to prepare for any analysis.
The compounds These check here can certainly ionize are analyzed utilizing these columns. Stationary period in these columns continues to be acidic or basic having detrimental or positive cost though cellular section can be a polar liquid as being the salt Answer in water.
Generally, silica gel is crammed in the significant-performance liquid chromatography columns thanks to its particle size and porosity that assists in more info separation of factors and silica gel is also an inert content that does not react with cell phases.
The content material of our Internet site is often available in English and partly in other languages. Decide on your preferred language and We're going to show you the content material in that language, if out there.
Ion exchange HPLC columns incorporates stationary phase with unfavorable or good cost, and mobile period as inorganic salt Remedy. Ion Trade HPLC columns are used with the analysis of compound based upon variances in the net demand in the molecules.
