Unaffected by particle colour, shape, composition or refractive index, the Multisizer provides size distribution by number, volume and surface area with an overall sizing range of 0.4µm to 1600µm and is the subject of a ISO Standard (13319) and a number of ASTM methods for such diverse applications as toner powders and cellular analysis.
m-VROC high shear rate/low sample volume viscosity measurement -
Some viscometers suffer from errors such as the formation of a film from at the air-solvent interface falsely gives much higher viscosity values and shear thinning behaviour.
The Rheosense VROC obtains a viscosity reading by measuring the pressure drop as a test fluid flows through a flow channel. RheoSense took this principle and created a dynamic microliter-scale sample viscometer by adding microfluidics, and reducing the size of the device with MEMS manufacturing.
As a result, VROC® technology offers capabilities that are well beyond the limits of conventional viscometers . With samples volumes as low as 50µl and high (1,000,000 1/s) shear rates, the VROC range is ideally suited to a wide range of applications from protein solutions to inkjet inks.
FlowCAM – particle shape and morphology -
The FlowCAM is ‘Particle Analysis with Vision’ a particle measurement system that allows you to see what lies below the size distribution curve by providing digital images of every particle measured.
Sample suspended in a fluid is passed through a flow cell perpendicular to the optical path. The optical system is similar to a microscope, and is used to capture real-time images of the particles in the fluid as the pass through the flow cell. For each overall image captured, the individual particles are extracted as separate small images and stored separately along with up to 26 individual particle measurements (such as aspect ratio, transparency, circularity etc.) for each image.
Particle identification can be carried using software filters so that for example the number of protein aggregates in a solution can be identified independently of the number of silicon oil droplets present where particle counters would simply count both.
Measuring Surface area is quick and easy with the Acorn AreA -
For the first time there is now a quick and easy way to measure surface area of particles in suspension, emulsions and colloids. The Acorn AreA uses NMR to measure the surface area of a wide range of particles in suspensions.
Liquid molecules in free solution have a different NMR relaxation time to those which are attached to the particle surface, the AreA measure the difference and calculates the surface area of the particles.
Ideal for looking at processes such as wet milling helping to save both time and energy costs, the Acorn can also be used to look at the effectiveness of dispersion process to see if the particles are fully wetted. No sample preparation is required and results are obtained in a couple of minutes rather than waiting hours for conventional techniques.
Delsa Nano zeta potential and Emulsion Stability and Colloid Stability -
Nanoparticle sizing and zeta potential measurements without needing to dilute your samples. Using patented technology the DelsaNano range measures particle size and zeta potential of colloids, emulsions and suspensions without the need to dilute the sample for most materials.
It can even measure the zeta potential of flat surfaces or films. Dynamic Light Scattering and Electrophoretic Light Scattering techniques are used to measure samples down to less than 1nm and at concentrations up to 40%. Special cell designs for example for low conductivity (non-aqueous) samples, and disposable cells simplify cleaning and maintenance and an optional auto titrator make obtaining pH profiles and Isoelectric points quick and easy.
SOP based software makes it easy to obtain reliable repeatable data quickly and easily and enables studies such as temperature and time based stability studies to be made.
Surface Area and Pore Volume Measurements -
The Thermo Scientific Surfer applies the principle of static volumetric gas adsorption under controlled temperature and pressure conditions to determine the micro structural properties of solids and powders.
Surfer determines rapidly and precisely the specific surface area (including krypton BET), Ultra micro, micro and mesopore size distribution, Specific pore volume and Exposed active sites concentration on catalysts.
Surfer is composed of two separate modules that can be used either independently or connected together, the analyser and the sample preparation degasser. Prior to the experiment, porous samples need to be dried and degassed.
Often the sample preparation is a time-consuming operation as it is dependent on the material nature and pore dimensions. The Thermo Scientific Surfer features a degasser module with three independent vacuum ports, so that up to three samples can be prepared at once, shortening the total experiment time.
Measuring Pore Size – Volume Distribution -
The mercury porosimetry technique is one of the most useful methods to investigate the porous structure of solid samples in a quantitative way. It provides reliable information about pore size/volume distribution, particle size distribution, bulk (envelope) density and specific surface for most porous solids.
Pressurization by Automatic Speed-up and Continuous Adjustment Logic, or Pascal, is a special operating principle developed by Thermo Fisher Scientific. The pressurisation procedure is critical to the accuracy of the analysis, too high a pressurisation rate and the pores are not completely filled at the correct pressure, too low a rate and the analysis time becomes very long.
The Pascal method ensures optimum information at the best speed and pressure giving the highest resolution and minimising analysis time.
Powder Flowability, Fluidisation, Granulation and Caking -
Powders change their state depending on their handling and storage. Predicting a powder’s behaviour requires an understanding of the state of the powder in the process and how the powder transitions from one state to another.
The Revolution Powder Analyser measures powder properties and how they change from the consolidated state to the fluidised state. Flowability, Granulation and Caking, and Fluidisation tests measure the powder in different powder states.
The RPA can measure individual properties or multiple measurements such as the powders ability to flow after fluidisation and provide density information.

POLA 2000 particle counter for oils, hydraulic fluids and water -
A number of regulatory authorities require the particulate contamination levels of fluids to be monitored in order to provide a safeguard to continued operation of plant and equipment, health of patients or effectiveness of clean up procedures such as filtration.
The POLA 200 is a light obscuration (blockage based system which is suitable for counting most fluids to standards such as ISO 4402, ISO 11171,NAS 1638 etc.
It’s simple to use, portable and reliable. Windows based software makes reporting of data quick and easy whilst providing the flexibility to display up to 50 size channels on any sample covering the overall size range from 1µm to 150µm.
Powder Tester – Powder Strength on storage
Knowing whether or not a powder will flow out of a container depends upon the strength it gains through storage. To allow a powder to flow the force making the powder move must be greater than its strength ( usually called Unconfined Yield Strength).
For most powders and granular material, the longer the material is exposed to pressure, the higher its unconfined yield strength will be. This will also be affected by other storage conditions such as temperature and humidity. In a lot of flow measurement tests, the time parameter is often ignored because sample analysis cells required to make many measurements over time are very expensive, and often do not have any means of applying the necessary pressure over prolonged periods. An affordable solution is now available – the Evolution Powder Tester.
The Evolution measures a materials response to applied pressure and calculates its unconfined yield strength. The measurement can be done at a single point, or at several pressures creating a Flow Function. The sample analysis cells can be stored in a temperature/ humidity controlled environment to simulate different storage conditions and measurements take typically less than 3 minutes to perform. The Evolution can provide you reliable reproducible data for the same cost as having a few samples measured by external laboratories.
