At LC Providers, we only function with models we definitely believe in to carry our buyers the very best chromatography devices and areas.
Agilent-certified support experts can be found around the world and sustain an inventory of real Agilent sections. They’ll promptly diagnose your program onsite and conduct any important repairs—ordinarily in only one visit.
The information of our Site is usually offered in English and partly in other languages. Choose your most popular language and We are going to teach you the information in that language, if obtainable.
Chromatography Columns Columns Perform a central job from the overall performance of chromatographic method. Very well-packed columns with steady overall performance in The full style Place of the system will provide steady products recovery and separation from contaminants.
The quantity of retardation primarily relies on the character in the analyte and also the composition of both of those stationary and cellular phases.
Often, authorities deal with an issue where by the elements they’re examining are different dimensions––This is when measurement exclusion columns support.
We style our columns with all the things you anticipate from the substantial-high-quality (U)HPLC column: higher resolution, Improved sensitivity, more rapidly analysis, dependable efficiency, very long column life span, and reproducibility. Each and every of our column types is on the market in get more info An array of particle sizes and column formats so that you can pick out the column best suited for your workflow.
To forestall the loss of stationary stage, which shortens the column’s lifetime, it is sure covalently to your silica particles. Bonded stationary phases
The affect is comparable with regard to duration. Shorter columns give low solvent consumption with quicker analyses, although for a longer time columns use far more solvent and just take more time.
Amongst the assorted types of columns used in HPLC, chiral columns Enjoy a crucial purpose in separating enantiomers, which happen to be mirror-impression isomers of a molecule. This article explores the different types of columns used in HPLC and presents a detailed introduction to chiral columns.
The compounds here People can certainly ionize are analyzed making use of these columns. Stationary period in these columns continues to be acidic or essential possessing detrimental or positive cost even though cell phase is actually a polar liquid as being the salt solution in water.
A quantitative HPLC analysis is usually less complicated than the usual quantitative GC analysis mainly because a hard and fast quantity sample loop presents a far more specific and exact injection.
Our columns fulfill higher design and style expectations, Consequently guaranteeing efficiency and scalability. DAC technological innovation permits reproducibility and robustness as time passes.
Thus scaled-down elements have an extended route to traverse and elute in the column later compared to larger types. Since the molecular quantity is connected to molecular fat, it is anticipated that retention quantity will rely to a point within the molecular weight in the polymeric supplies. The relation involving the retention time along with the molecular pounds is revealed in Figure (PageIndex 4 ).
