Postnova Analytics GmbH: Revolutionizing Particle and Polymer Characterization

Postnova Analytics GmbH is a leading provider of advanced analytical solutions for particle, nanoparticle, macromolecule, and polymer characterization. The company specializes in the development and manufacture of cutting-edge Field-Flow Fractionation (FFF) systems and light scattering detectors that enable scientists to determine the molar mass, size, composition, and elemental distribution of complex samples with unparalleled accuracy.

With over two decades of experience in the field of analytical instrumentation, Postnova Analytics has established itself as a trusted partner for researchers across various industries. The company's innovative FFF technology offers several advantages over traditional chromatography-based methods such as high resolution separation without column packing material or stationary phase interactions. This makes it an ideal choice for analyzing complex samples that are difficult to separate using conventional techniques.

Postnova Analytics' FFF systems are available in different configurations to suit various applications ranging from particle size analysis to protein aggregation studies. The company's flagship product is the AF2000 MultiFlow system which combines multiple FFF channels with online dynamic light scattering (DLS) and multi-angle light scattering (MALS) detectors for comprehensive characterization of nanoparticles, proteins, polymers, liposomes etc.

In addition to its FFF systems, Postnova Analytics also offers a range of complementary instruments such as refractive index detectors (RI), UV-vis spectrophotometers (UV), fluorescence detectors (FLD), electrochemical detectors (ECD), etc., that can be integrated into its FFF platforms or used standalone depending on the application requirements.

One area where Postnova Analytics has made significant contributions is in the field of polymer analysis. Polymers are ubiquitous materials used in various industrial applications ranging from packaging materials to biomedical devices. However, their properties depend on their molecular weight distribution which can vary widely even within a single batch due to factors such as chain branching or crosslinking. Accurate determination of polymer molar mass distribution is therefore critical for quality control and product development.

Postnova Analytics' FFF technology offers several advantages over traditional gel permeation chromatography (GPC) methods for polymer analysis. Unlike GPC, FFF does not require the use of column packing material or solvents which can affect the sample properties. This makes it possible to analyze polymers in their native state without altering their structure or composition. Moreover, FFF can separate polymers based on their hydrodynamic size rather than molecular weight which provides a more accurate representation of the true molar mass distribution.

Postnova Analytics has also developed specialized software tools such as NovaMALS and ASTRA that enable users to analyze complex data generated by its instruments with ease. These tools provide advanced features such as automated peak detection, baseline correction, and deconvolution that help researchers extract meaningful information from their data quickly and accurately.

In conclusion, Postnova Analytics GmbH is a company at the forefront of analytical instrumentation development with a focus on particle and polymer characterization using Field-Flow Fractionation technology. Its innovative solutions have enabled researchers across various industries to gain new insights into complex samples that were previously difficult to analyze using conventional techniques. With its commitment to innovation and customer satisfaction, Postnova Analytics is poised to continue revolutionizing analytical instrumentation in the years ahead.
