Highest flexibility in surface and pore analysis

NOVA
For BET-measurements and for pore analysis the NOVA is available as 1-, 2-, 3- and 4- sample stations equipment and is used in research and development as well as in quality control. It is characterized by a very good price-performance-ratio and guarantees with the multipoint configuration a sufficient quantity of measurements for many applications.

QUADRASORB
This analyzer series consists of the QUADRASORB SI and the QUADRASORB SI-MP. Both analyzers have 4 sample stations with a pressure sensor for each of them, 4 separate stations for continuous determination of the saturation vapour pressure P0 as well as 4 dewars to enable individual measurements and independent re-start of each sample station. With these options the QUADRASORB SI realizes a significant higher throughput of samples than the NOVA.

AUTOSORB
The AUTOSORB is available as 1-station and 6-stations analyzer (AUTOSORB-iQ and –6B) as well as basic- and micropore instrument with turbo molecular pump and additional pressure transducers (AUTOSORB-iQ, -6B-MP). Quantachrome presented the new AUTOSORB-iQ in 2010: The AUTOSORB-iQ offers so many new features in one instrument, that it is the new benchmark in gas adsorption for surface and pore size analyses!

Characterisation of stability of dispersions under original conditions

The patented TURBISCAN-principle is a standard to study the stability of original dispersions under original storage conditions. Only the TURBISCAN measures both the transmitted and the backscattered laser light of dispersion dependent on the height of the sample cell - and without any additional force which can change the complex structure of your emulsion or suspension, so that the TURBISCAN prevents the risk that the measurement will not characterize the nature of your original sample. With the TURBISCAN-principle there is a way to characterize opaque samples by interpretation of backscattered light intensities to not only detect sedimentation or creaming effects, but also coalescence of particles and droplets as a function of time.

• TURBISCAN Lab incl. Temperature regulation up to 60°C (down to +4°C as option)
• TURBISCAN CLASSIC
• TURBISCAN ONLINE for the fast and near-process-characterization of the average particle size of opaque samples
• TURBISCAN AGS: Multisampler for max. 54 samples

The TURBISCAN-principle is standard for many industries to characterize the stability or the instability behaviour of liquid dispersions. Liquid dispersions can be liquid/liquid (Emulsion), liquid/solid (Suspension) or liquid/gas (Foam) systems.

The mission of the manufacturer FORMULACTION is to provide the best solutions to characterize concentrated dispersions (emulsions, suspensions and foams), in terms of stability and microrheology, for different application fields like Pharmaceutical, Cosmetic, Food, Petroleum, Electronic…

The instruments range uses innovative optical measurement based on Multiple-Light-Scattering. FORMULACTION has developed patented technologies to characterize concentrated dispersions without sample preparation (no dilution, non intrusive method).

Today FORMULACTION offers two ranges of products

• Stability analysis of concentrated dispersions
• Microrheology analysis of soft materials

FORMULACTION technologies cross link Particle Characterization and Rheology analysis.

DT-1202: particle-size and zeta-potential in concentrated dispersions

Instrumentation for characterizing Particle Size, Zeta Potential, Compressibility, Bulk viscosity, Non-aqueous Conductivity, Debye length and other properties of Concentrated Dispersions, Emulsions and Porous bodies.

Dispersion Technology Inc. (DT), was established in 1996 intentionally for developing analytical instrumentation suitable for characterizing particle size distribution and zeta potential in concentrated complex liquid systems, such as pharmaceuticals, cement, ceramics, paints, emulsions, and many more. Since that time DT has designed and is currently marketing worldwide a family of such instruments that are based on ultrasound. Ultrasound turned out to become a very versatile tool yielding information on particle size and zeta potential, but variety of parameters characterizing these complex systems, such as compressibility, longitudinal viscosity, micro-viscosity, surface conductivity, electric charges of macromolecules, etc. These methods can be applied for characterizing zeta potential not only in liquid particulates but in porous bodies as well.

Operating Procedure
The user fills the sample chamber with 30 - 100 ml of sample, defines the sample in a simple dialog box, selects the desired experiment protocol, and clicks on "RUN". When the measurement is complete, the user empties the sample, and then rinses the system with water or suitable cleaning solution.

Available instruments
DT 1202: Particle size and zeta potential
DT-300/310: Zeta potential probe without/with titration
DT-100: Particle sizing
DT-500: Online Particle size and zeta potential
DT-600: Rheometer longitudinal
DT-700: Non-aqueous conductivity

Available Options
Automatic Titration with 1or 2 burettes
pH / Temperature measurement
Conductivity measurement, aqueous and non-aqueous
Circulating pump for very viscous samples
Ports for remote "on-line" measurements
Rheology longitudinal
Temperature heating control
