Instruments of the NOVAtouch series are the preferred choice for hundreds of research laboratories around the globe. These fast vacuum-volumetric gas sorption analyzers provide research and Q&C labs with the capacities required for precise high throughput analysis of specific surface areas and pore size distributions at a low cost. The combination of up to four analysis stations and four sample preparation station sin one instrument not only reduces the footprint but maximizes the productivity. Never before has the operation been as intuitive as it is now due to the integrated touch screen controls.

Facile determination of specific surface area and pore size distribution – the NOVAtouch

The properties of porous materials are heavily influenced by their specific surface area, the pore volume, and the pore size distribution. Determining these parameters does not need to be difficult and time consuming. Instruments of the NOVAtouch series are fully automated vacuum-volumetric  gas sorption analyzers that can measure up to four samples simultaneously, allowing to carry out four BET and pore size analysis while degassing up to four more samples at the same time.
All instruments of the NOVAtouch series work as stand-alone instruments. The void volume can be measured using the classic Helium method or the proprietary and time-saving NOVA-mode. The accuracy of the measurement is improved by measuring the saturation pressure using a dedicated P₀-cell and transducer while also speeding up the measurement. A cryogenic liquid sensor (CLS) increases the sensitivity of the instrument by facilitates a constant small cold volume throughout the entire measurement (max. 40h). The integrated gas inputs allow to connect up to three adsorptives simultaneously, and the possibility to measure CO₂ isotherms at 273 K allows the rapid characterization of microporous carbons.
The integrated touch screen renders the NOVAtouch a real stand-alone instrument, allowing the user to select and start degassing programs with multiple heating rates and dwell times in flow or vacuum mode. An external computer can be used to control the NOVAtouch, upload analysis and sample preparation programs, and analyze data using the TouchWin^TM software package. The NOVAtouch is available with two and four analysis station, making it easy to identify the prefect instrument for every task.

Anton Paar offers two instrument series to analyse particle sizes: TheLitesizer^TM series and the PSA series. The difference between these series is the measuring principle and therefore the measurable size range of the particles.
The Litesizer^TM series analyses the following parameters via light scattering principle:

• Particle sizes bigger 0,3 nano meters (via DLS)
• Zeta potential (via ELS)
• Molecular mass, refractive index and transmission

The PSA series determines particle sizes in the range from nano meters to 2,5 millimeters in dry or wet dispersion via laser diffraction.

The laser diffraction technique is an established method to measure particle sizes from the upper nanometer to the millimeter range. Anton Paar’s PSA instruments provide accurate and reproducible measuring signals. This guarantees full compliance with the ISO 13320 and USP <429> standards.
Take advantage of the multiple-laser technology, the flexibility to measure dry and liquid samples with one setup. The PSA product series delivers high measuring accuracy and repeatability at a robust design.
Anton Paar’s PSA series incorporates more than fifty years of experience. The world's first laser diffraction particle size analyzer – the first-ever PSA – was invented in 1967. The three models PSA 990, PSA 1090, and PSA 1190 are designed to measure a wide range of particle sizes in liquid dispersions or dry powders.

Autosampler for dry and liquid samples
Anton Paar’s autosampler for the PSA series is the only sampler on the market that can be used for both wet and dry dispersions, and is able to automate the sample measurement process. Available for the PSA 990, PSA 1090, and PSA 1190 models, the autosampler picks up and pours samples automatically into the particle size analyzer, enabling you to focus on other tasks. The autosampler is suitable for both industrial and lab applications.

Measurement of liquid and dry samples? The PSA series integrates both in one single instrument
PSA instruments are the only particle size analyzers that can be configured with fully integrated liquid and dry dispersion modes in one instrument. This unique design eliminates the need for the operator to handle several accessories or make manual adjustments. The software enables the switching between liquid and dry dispersion modes with a single mouse-click, which saves time and prevents operation errors. There is no need to exchange the hardware, re-validate, or re-align sensitive optics when switching between dispersion modes.

Stability for a lifetime? The unrivaled robust design of the PSA series makes it possible
The unique optical bench design has all optical components permanently mounted on a cast-iron base plate. This ensures alignment-free operation, even in the harshest environments. The rugged design ensures that the system remains aligned and this reduces the maintenance requirements to a minimum throughout the entire life of the instrument.

Broad particle size range? The PSA series measures particle sizes from submicrons to a few millimeters
The single-laser PSA 990 covers a wide measuring range of 0.2 μm to 500 μm. For an even broader range, PSA 1090 and PSA 1190 have a unique optical design for diffraction analysis, which includes multiple lasers. While PSA 1090 has been designed with two lasers to resolve particles as small as 40 nanometers, PSA 1190 contains an additional third laser to cover the full measurement range of up to 2.5 millimeters.

Non-ambient X-ray diffraction (XRD) has become an indispensable technique to understand the influence of temperature, atmosphere or pressure on materials of any kind. Besides its relevance for conducting research, this knowledge is essential for optimizing technical processes and performing quality control in industry.

The focus of interest in an XRD experiment is the sample and this deserves sample stages optimized for the specific application. Sample stages from Anton Paar ensure a precisely controlled sample environment in terms of temperature, atmosphere and pressure.

Automatic sample height compensation also guarantees the correct geometrical position of the sample in the X-ray beam throughout the experiment. Use of high quality materials avoids unwanted chemical reactions between sample and stage components and ensures the long lifetime of the equipment.

Due to their popularity Anton Paar stages fit to all commercial diffractometers and are fully integrated solutions in their software and hardware for ease of use.

The HTK 1200N has been the attachment of choice for in-situ XRD studies on flat samples up to 1200 °C for many years. The novel capillary extension turns this well-known oven chamber into a powerful capillary heater.

Due to its environmental heater, there is virtually no temperature gradient in the sample, even in samples of up to 5 mm thickness.

The BTS 150/500 Benchtop Heating Stages are the first commercial non-ambient stages for benchtop diffractometers and extend their applicability to in-situ XRD studies. Measurements can be performed between -10 °C and 150 °C with BTS 150 and from ambient to 500 °C with BTS 500.

Both instruments are extremely compact in design to fit into the restricted space of typical benchtop diffractometers. The control electronics are integrated in the heating stages and provide easy operation.

Advanced True Powder Rheology - A Toolbox for Powder Challenges
Working with powders and granular media can be challenging, therefore, efficient quality control and smooth powder processing is important. Powder behavior is affected by many internal influences like particle size and shape, but also by many external influences such as temperature and humidity. These influences, and thereby the powder behavior, can change during storage or a manufacturing process. The Anton Paar Powder Cell offers a toolbox of measurement methods for determination of a variety of powder properties and handling parameters for optimized processing and storage. A wide range of dedicated powder measurement methods are implemented in the software and most only take a few minutes, ensuring efficient quality control and smooth processing.

Measuring methods

• Pressure Drop Method: Determination of volumetric flow for incipient/full fluidization. Useful for pneumatic conveying, powder filling, and for sample preparation.
•  Air retention capacity: Describes the time necessary for the particles to fully settle after they were fluidized, useful for pneumatic conveying, filling and tableting processes.
• Cohesion Strength: Is a measure of the internal resistance of the powder to flow, and thereby a measure of powder flowability in a deaerated state. Can be used with all fluidizable powders as a quick and simple QC tool or for differentiating even very similar powders. 
• Warren-Spring Cohesion: This method is used to determine the cohesion strength of cohesive powders in a consolidated state. The results can be used for quality control, powder characterization (elasticity, cohesion, flowability) and to study caking behavior. 
• Wall Friction: describes the friction between powder and a solid body of nearly any material. Useful for silo/hopper design or finding friction coefficients.
• Compressibility: is a measure of the relative volume and bulk density change a sample undergoes when pressure is applied. Being a simple test, it can be used to identify the nature of powder flow with Carr Index and Hausner Ratio.
• Flow curves: describe the apparent powder viscosity of powders in dependence of the shear rate and the state of fluidization (non-, sub- and fully fluidized). Useful for choosing ideal processing conditions for powders..
  Other methods and parameter: Segregation, Tensile Strength, Permeability

• The modularity of MCR rheometer with all its accessories makes it possible to characterize powders in all processing steps, e.g. for powder coating: from the fluidized bed reactor, to pneumatic conveying and powder spraying and even tribological characterization of the hardened coatings.
