Particle & Molecular Size/Charge Analyzers
Zetasizer Range
Instruments in the Zetasizer range are used to measure particle and molecular size from less than a nanometer to several microns using dynamic light scattering; zeta potential and electrophoretic mobility using electrophoretic light scattering; and molecular weight using static light scattering. The Zetasizer system is available in a range of variants, including the new Zetasizer Pro and Ultra. These two new systems offer unprecedented ease-of-use and flexibility, along with empowering user guidance and novel measurement techniques such as MADLS® and Particle Concentration.

Evaporative Light Scattering Detector
ELSD-LTII
The ELSD-LTII utilizes a high-efficiency LED and enhanced digital signal treatment to minimize noise and deliver optimum sensitivity for trace analysis. An innovative cell design also reduces band broadening and allows sensitivity levels below 200 picograms. The high-performance optical detection system can also be used for combinatorial chemistry and high-throughput screening applications. The new Low Temperature Evaporative Light Scattering Detector (ELSD-LTII) is an easy-to-operate, universal detector that identifies analytes with uniform sensitivity regardless of their spectroscopic properties. It is not a spectroscopic detector. Instead, it removes the mobile phase through evaporation and then makes a light scattering measurement of the dried analyte particles.

Scattered Light Dust Measuring Devices
The reliable way to detect low dust concentrationsLight scattering by dust particles is a measurement principle that allows even very low concentrations of dust to be detected. Depending on the system-specific requirements, either forward scattering or backward scattering can be used in this context. Both measurement principles return stable and reproducible measurement results, regardless of the gas velocity, humidity, or dust particle charges.

Dynamic Foam Analyzer
DFA100
Our DFA100 instrument for analyzing foams measures the foamability of liquids and the foam stability based on precise measurements of the foam height. With flexibly deployable modules, it also measures the liquid content of the foam or analyses the foam structure with regard to bubble size and distribution. The DFA100 assists in the optimization of foam-forming products or, in the case of unwanted foam formation, helps with specific foam prevention.

Multi-Angle Light Scattering Detectors
Since the 1990s Postnova has been a leading innovator and developer of special advanced online Light Scattering solutions for coupling with chromatographic separation systems. The first model was the PD2000 - Static Light Scattering detector for coupling with Asymmetric Flow FFF. Later on the models PN3020 SLS and PN3070 MALS have been launched. Based on these over two decades of practical experience, Postnova has collected a unique competence in the area of Laser Light Scattering and has developed the unique PN3621 MALS - Multi-Angle Light Scattering detector series. The model PN3621 MALS is a completely new type of high performance MALS detector system with a unique range of specifications.

Dynamic Mechanical Analyzers
Dynamic Mechanical Analysis measures the mechanical properties of materials as a function of time, temperature, and frequency. In addition to basic material properties, DMA also quantifies finished part characteristics, reflecting the important contribution that processing has on end-use performance. DMA is commonly used to measure glass transition temperatures and secondary transitions, orientation caused by processing, cold crystallization, cure optimization, filler effects in composites, and much more. DMA provides an accurate measure of material stiffness (modulus) but also other important mechanical properties such as damping, creep, and stress relaxation.

Light Meters
A light meter is a very sensitive electronic measuring device used to help monitor the illumination of any given area. Most light meter devices are small in size, simple to operate and equipped with an easy-to-read lighted screen made of special glass. Typically, a heavy-duty housing protects the light sensor inside the light meter from damage. A light meter is used for measuring brightness in lux (lx), foot candle (fc) or candela per square meter (cd/m²)measuring units. Some light meter devices are equipped with an internal memory or data logger to record and save measurements. The measurement of light intensity with a light meter is becoming increasingly important in the workplace due to safety concerns. Light measurement is also necessary to determine the best location and angle when installing and adjusting solar panels.

Real Scene Lighting
LightSTUDIO
Image Engineering GmbH & Co. KG
Test charts are used to test digital cameras and to perform objective measurements. But there are certain aspects in testing a camera that require a real scene. One of these aspects is the correct white balancing for different types of illuminants. Another aspect might be the determination of the visual loss of detail due to noise reduction or the amount of noise in an image.
