At LC Companies, we only work with manufacturers we really believe in to carry our customers the best possible chromatography tools and areas.

Third-get together experience might not Review on the deep knowledge and specific instruction of the Agilent-Accredited support Specialist.

You can find four different types of HPLC columns used in analysis, dependant upon the research. Proceed looking through To find out more.

This web site does not exist as part of your chosen language. Your preference was saved and you may be notified after a webpage is often considered with your language.

Right after loading the sample, the injector is turned towards the inject placement, which redirects the cell period in the sample loop and onto the column.

Concentration and anticipated peaks: Think about the amount of your analytes and their peak heights. Narrower columns deliver better resolution for carefully eluting peaks.

HPLC works by using a moderate to significant pressure to achieve the specified circulation level in the solvent through the chromatographic column as tiny particles have a lot more exceptional resistance to stream.

Ion-exchange columns have a stationary phase that is certainly positively or negatively billed, in addition to a cellular section that may be picked to connect with the target compound is suitable for separating billed compounds which include ions and ionic compounds.

Porous stationary section in these columns enables the separation with the elements In line with their size. Mix of polymers like polysaccharides and silica is used as stationary section in these columns. check here Little sample molecules penetrate from the pores of stationary stage even though the big molecules penetrate partially in to the pores.

Separation in the sample factors happens on The premise from the polarity of your sample components. Sample parts possessing extra polarity interact a lot more with polar stationary section causing separation from your fewer polar element that interacts with a lot less polar mobile phase.

-hydroxybenzoic acid elutes far more gradually. Despite the fact that we could take care of totally both of these solutes working with mobile period that may be 16% v/v acetonitrile, we are unable to take care of them In the event the cellular phase is 10% tetrahydrofuran.

Sartorius chromatography consumables go over the more info full choice of separation technologies and methodologies out there to support any process and any mo...

Packed Chiral Columns: These columns comprise a chiral stationary phase packed right into a column. Packed chiral columns can be found in each typical-stage and reverse-stage configurations, giving flexibility in separation.

Ion Trade HPLC columns contains stationary phase with destructive or favourable cost, and cellular phase as inorganic salt Option. Ion Trade HPLC columns are used for that analysis of compound depending on dissimilarities in The online cost with the molecules.
