Jordi NP DVB Polyamino

by JORDI

Jordi NP DVB Polyamino

NP DVB Polyamino columns contain secondary amino groups which quaternize in acidic solutions allowing mixed mode ion exchange and normal phase separations. Normal phase separations are used to separate molecules based on their polarity as opposed to their hydrophobiicty as in RP. Weakly polar compounds are found to elute first followed by more polar components. This can be used to fractionate a sample based on the functional groups present in each molecule. Gradients are the opposite of those typically used for RP chromatography and thus a gradient from a non-polar solvent to a more polar solvent is used.

Jordi NP DVB Polyamino columns provide the following benefits:

class based separations
high column plate counts
mixed mode separations combining ion exchange and normal phase
rapid recovery of the phase following gradient analysis
rugged - solvent changes will not damage columns
solvent compatibility – 100% organic to 100% aqueous buffers
wide pH range - pH values from 0 to 14.
long column life - 3 month warranty Standard

Similar columns from other manufacturers to Jordi NP DVB Polyamino

Up to 10 unique Brand families from other Vendors with the same Mode and the same Modification.

How similarity is calculated

Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.

A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.

No other-Vendor Brand family with the same Mode and Modification meets the comparable-data and similarity thresholds.
