Make sure you confirm you prefer to to receive internet marketing and marketing e mail messages about Thermo Fisher Scientific products and services.
Little molecules are ions and compounds of molecular excess weight normally less than 900 daltons. These compounds may be properly separated and analyzed by HPLC, UHPLC and LC-MS employing mostly silica particles or monolithic stationary phases which has a broad array of column chemistries (modifications).
Pay a visit to uHPLCs now to examine our number of HPLC columns and related products that are specially intended to fulfill your analytical demands.
*For gradient separation, a improve on the cell phase isn't recommended. Right here, A further column of precisely the same specification must be preferred or an adaption in the dead volume or maybe the isocratic stage originally in the gradient.
These HPLC columns have stationary phases with chemically modified hydrophobic surfaces the place porous silica stationary phases have already been modified with ligands of assorted chemistry and measurements. These columns Possess a non-polar or significantly less polar stationary phase than the greater polar mobile phase.
As with all Sartobind® membranes, the big pore framework is especially suited to massive biomolecules.
The capsule and cassette formats eliminate the necessity for column packing, minimizing the required facility space
Cation Trade columns are used to individual positively billed ions, like sodium and potassium. Anion Trade columns are used to separate negatively billed ions, including chloride and sulfate.
By the top of this blog site publish, you'll have a very good idea of the different types of columns obtainable in the market and be capable to make an informed decision when picking an HPLC column that satisfies your specifications the most beneficial.
These pages list our item offerings in these areas. Some merchandise have restricted regional availability. When you have a specific concern about merchandise out there in your neighborhood, you should Make contact with your neighborhood profits office or representative.

Just after their implementation, process transfer to sub-2 μm elements can even be permitted in upcoming - and thus time and price-economical utilization of UHPLC can even be doable.
See 1st-hand how Sartobind® Immediate A delivers a tenfold boost in productiveness with Sartorius’ new chromatography membrane. Find out more in regards to the item’s scalability, from PD to business, and the way to remove the mAb capture bottleneck With this webinar.
