FFF Sample Analysis

Sample Analysis Services

Postnova Analytics offers a variety of unique sample analysis services for the characterization of biopolymers, proteins, liposomes and nanoparticles. Our European Application Laboratory Center EAC and our American Application Laboratory Center AAC represent the worldwide biggest and most advanced labs offering sample analysis services based on Field-Flow Fractionation and Light Scattering.


The service depends on the sample type. The numbers are listed below, prices are on request. A comprehensive report in Word/PDF format as well as raw data will be provided to the customer. This service is ideal for customers who would like to get access to the unique capabilities of FFF-LS but don’t want to invest in own instrumentation. Also, customers who have one-time samples, an urgent need for sample characterization services or even short resources in their own FFF lab, may use the Postnova EAC/AAC sample analysis services to their advantage.

Postnova also has the required resources to offer these services to customers having continuous samples on frequent basis in larger quantities. In close discussions with the customer Postnova determines the optimized measurement procedures and creates a customized service for every client, while maintaining the highest QC levels at any time.
