Our columns fulfill substantial layout criteria, Hence ensuring performance and scalability. DAC technological innovation allows reproducibility and robustness over time.
Agilent-Qualified service professionals can be found across the globe and manage an inventory of legitimate Agilent sections. They’ll promptly diagnose your technique onsite and conduct any required repairs—usually in a single visit.
, such as, shows retention situations for 4 weak acids in two mobile phases with just about identical values for (P^ primary ). Even though the get of elution is identical for both of those cellular phases, Every single solute’s retention time is impacted differently by the selection of natural and organic solvent.
A different method, mass spectrometry, has sure positive aspects about other approaches. Mass spectra may be obtained quickly; only smaller quantity (sub-μg) of sample is required for analysis, and the data provided by the spectra is quite educational from the molecular composition. Mass spectrometry also has robust advantages of specificity and sensitivity in contrast with other detectors.
Chemical mother nature: Polarity, hydrophobicity, and cost of one's analytes will impact their conversation Along with the stationary section.
Concentration and envisioned peaks: Look at the quantity of your analytes as well as their peak heights. Narrower columns offer improved resolution for intently eluting peaks.
Sign up for Sartorius as we investigate ways to transfer a standalone batch mAb chromatography system to some linked DSP.
The stationary phase is a granular content with quite compact porous particles in the separation column.
Most column housing is product of stainless steel due to the check here fact stainless is tolerant towards a substantial a number of solvents.
Besides that, there are the scale of your columns in query – specially, diameter and duration.
Large functionality liquid chromatography (HPLC) is really a kind of liquid chromatography which is used to independent the individual components of fascination present in combination and/or dissolved in sample Option. It is based on pumping of mobile stage through the packed column underneath substantial tension. The fundamental theory linked to HPLC is based around the phenomenon of column chromatography in which the mobile stage is pumped by way of a packed column by implementing high strain.
Ion-exchange: Separates charged analytes dependent on their own ionic interaction Together with the stationary phase. Pick a cation-Trade or anion-exchange column according to your analytes’ charge.
HPLC does have low sensitivity for specific compounds, and check here a few can't be detected as They're irreversibly adsorbed.
Superior-overall performance liquid chromatography (HPLC) entails the injection of a little volume of liquid sample into a tube packed with little particles (three to 5 microns (µm) in diameter called the stationary section) wherever personal elements with the sample are moved down the packed tube with a liquid (mobile phase) forced throughout the column by substantial stress delivered via a pump.
