Petroleum asphaltenes

Vertical Tabs

Overview

Characterization of petroleum asphaltenes by Field-Flow Fractionation (FFF)
During the past decades, FFF has been applied successfully for the separation, characterization and fractionation of a wide variety of large-size materials, including petroleum asphaltenes.

Now 25 years in business, Norlab is a specialist supplier of Separation Science & Dissolution Instruments and Accessories, Laboratory Fluid Handling Solutions and more...
To celebrate our 25th anniversary, we are planning special deals and promotions throughout the year. We encourage you to stay informed by signing up for our newsletter.

Separation, characterization and fractionation of nearly any macromolecules or nanoparticles
The Postnova modular FFF platform can be configured for any single or combination of several of the five FFF subtechniques - Asymmetric Flow FFF (AF4), Hollow-Fibre Flow FFF (HF5), Electrical FFF (EAF4), Centrifugal FFF CF3) and Thermal FFF (TF3). Because of this flexibility, it can be used for the separation, characterization and fractionation of nearly any macromolecules or nanoparticles. The Postnova platform can be also configurated for Size Exclusion Chromatography (SEC or GPC). You can easily switch from FFF to SEC and vice versa. The NovaFFF software takes care of control, data acquisition and calculation.

Postnova AF2000 MT mid temperature MultiFlow FFF system
The system can be configured for Asymmetric Flow Field-Flow Factionation (AF4), Hollow Fiber Flow Field-Flow Factionation (HF5) and Size Exclusion Chromatography (SEC).

Postnova TF2000 Thermal FFF system
The system can separate simultaneously polymers and particles without the limitations associated with GPC/SEC. The separation takes place according to molecular weight AND chemical composition, thus making the TF2000 Series the ideal choice for difficult polymer separation.

Postnova 21-angle MALS detector - the ideal detector for ultra-high molar mass
The Postnova 21-angle MALS detector has been especially developed for coupling with FFF systems – to the opposite of previously available MALS detectors which were designed with chromatography (SEC/GPC) in mind, that is for smaller molar mass.

High sensitivity online Dynamic Light Scattering detector, special customized for use connected to FFF
Online DLS measurements using a special flow cell can be perfomed to obtain particle size (Rh) and molecular weight (Mw) distributions of particles and molecules separated by Postnova Asymmetric Flow FFF (AF4), Centrifugal FFF (CF3) and Thermal FFF (TF3) systems.
