Thermal Mechanical Analyzer

Thermal Mechanical Analyzer

Thermomechanical analysis (TMA) is a technique used in thermal analysis, a branch of materials science which studies the properties of materials as they change with temperature. Thermomechanical analysis is a subdiscipline of the thermomechanometry (TM) technique. Thermomechanometry is the measurement of a change of a dimension or a mechanical property of the sample while it is subjected to a temperature regime. An associated thermoanalytical method is thermomechanical analysis. A special related technique is thermodilatometry (TD), the measurement of a change of a dimension of the sample with a negligible force acting on the sample while it is subjected to a temperature regime. The associated thermoanalytical method is thermodilatometric analysis (TDA).

Particle Size Analyzer SALD

Particle Size Analyzer SALD

Particle size analysis, particle size measurement, or simply particle sizing is the collective name of the technical procedures, or laboratory techniques which determines the size range, and/or the average, or mean size of the particles in a powder or liquid sample. The particle size can have considerable importance in a number of industries including the chemical,food, mining, forestry, agriculture, nutrition, pharmaceutical, energy, and aggregate industries.

Particle Size Analyzer SALD 2300 measurement range is 17nm to 2500μm.
Applicable to a Wide Range of Applications Using Optional Units and Application Sof tware Packages.
1. Wide applicability
Using the SALD-MS23 sampler, the measurement range is 17nm to 2500μm for wet measurement.
Various sample amounts (Suspension) can be selected according to measurement objects and purposes.
Sample amount for SALD-MS23 is variable: 100mL, 200mL, or 300mL.
2. High sensitivity / High concentration
By enabling measurement under wide particle concentration conditions (0.1ppm to 20%), changes in particle size distribution depending on particle concentration can be evaluated.
Previously, the particle concentration of a sample had to be adjusted to meet the optimum conditions of analyzers by dilution or concentration using a centrifuge. In these cases, changes in particle size distribution, such as agglomerations or dispersions, could not be considered.
Dispersions and agglomeration can be caused by dilutions.
In some cases, dilutions can accelerate dispersions, but in other cases, they can create agglomerates. To ensure optimum, the initial particle concentration must be determined without dilutions or concentrations. After the evaluation of particle size distribution at the initial state, the effects of particle concentration from dispersions and agglomerations must be evaluated.
Wide particle concentration range must be covered to evaluate the dissolution process of sample particles.
This is necessary because the progress of dissolution makes the particle concentration low in comparison to the first particle concentration.SALD-2300 can measure particle size distribution under the conditions of particle concentration from 0.1ppm to 20%.
When the sampler SALD-MS23 or batch cell SALD-BC23 is used, measurements are possible under conditions of concentration from 0.1ppm to 100ppm.
When the high-concentration sample measurement system SALD-HC23 is used, high-concentration samples up to 20% can be measured because the negative effects of multiple scattering are prevented.
Measurement without dilution of hand cream
In the case of hand cream, dilutions make the particle size distribution narrow. Measurements without dilutions must be done to obtain accurate measurement.
Evaluation of a fine particle included in red wine
The low-concentration sample can be measured as an undiluted solution.
Measuring it in this state can remove the influence of dispersion or agglomeration by the concentration operation.
Evaluation of negative electrode material of a secondary battery
The agglomeration particle (micrometer range) has been dispersed to the fine particle (sub-micrometer range) by dispersion processing using a homogenizer. The sample (sample that absorbs light like the carbon black) that doesn’t transmit light easily can be measured based on the improvement in sensitivity.

Zeta Potential Analyzer

Zeta Potential Analyzer

Zeta potential is a scientific term for electrokinetic potential in colloidal dispersions. In the colloidal chemistry literature, it is usually denoted using the Greek letter zeta (ζ), hence ζ-potential. From a theoretical viewpoint, the zeta potential is the electric potential in the interfacial double layer (DL) at the location of the slipping plane relative to a point in the bulk fluid away from the interface. In other words, zeta potential is the potential difference between the dispersion medium and the stationary layer of fluid attached to the dispersed particle.

NanoPlus-2 Zeta Potential Analyzer (-200 mV to +200 mV) A unique instrument for zeta potential measurements in suspensions. The measurement principle is based on electrophoretic light scattering method. Allows for accurate measurements in highly concentrated and dark suspensions of concentrations from 0.001% up to 40%.
