Peptide Bioanalysis Solution Guide-hplc vials manufacturer Corporation

Avoid the use of glass when preparing your samples,as non-specific binding may occur. Add a carrier protein (0.05% plasma by volume,for example) to solvent and standard diluent to minimize non-specific binding. LC and column passivation may be necessary when analyzing peptides,as they can retain on untreated surfaces.

What is the right quality of water for HPLC analysis?

Ensure that an organic solvent is flushed through the HPLC system and column at least once every 48 hours to kill unwanted microbial growth. Alternatively add a small amount of sodium azide to the aqueous solvent to inhibit growth. NoteNever allow a HPLC column or system to stand with water or buffer in it for an extended period of time.

Aug 15,2020· Retention Factor. Since K c is a factor that is wholly dependent on a particular column and solvent flow rate,a quantitative measure of the affinity of a compound for a particular set of mobile and stationary phases that does not depend on the column geometry is useful. The retention factor,k,can be derived from K c and is independent of the column size and the solvent flow rate.

HPLC Separation Modes-Polarity,Phases,& Chromatography

It is typical for normal-phase chromatography on silica that the mobile phase is 100% organic; no water is used. Reversed-Phase HPLC. The term reversed-phase describes the chromatography mode that is just the opposite of normal phase,namely the use of a polar mobile phase and a non-polar [hydrophobic] stationary phase.
