In this application note, a non-ionic surfactant micelle Tween 20 and an ionic surfactant micelle SDS were studied by investigating their particle sizes and the effect of temperature on their phase behaviors through dynamic light scattering (DLS) technology.
The particle sizes of high concentration pigments (red and yellow samples) had been characterized successfully by the DLS technology of the BeNano 90 Zeta. Using the capillary sizing cell compatible with the BeNano 90 Zeta, even samples with high concentrations and low transmittance can be analyzed to yield reliable and accurate results.
The BeNano 90 Zeta provides accurate and rapid characterization of particle size and zeta potential of Bovine Serum Albumin (BSA) in an aqueous solution as will be detailed in this application note. The results show the BeNano 90 Zeta’s capability in low molecular weight proteins particle size and zeta potential measurement, even though the scattering intensity is weak.
The weight-average molecular weight measurement of the PEO standard was performed in this application note, and the measured value was determined through the Debye plot. The measured value is quite close to the literature value, thereby demonstrating that the BeNano 90 Zeta is a useful and reliable tool for characterizing the molecular weight of proteins.
Zeta potential is a scientific term for electrokinetic potential in colloidal dispersions. One of the factors to affect the zeta potential values is the chemical composition at the particle surface, and the solution environment in which the particles are dispersed. In this application note, the relation between the zeta potential and pH is investigated by measuring the zeta potentials of a commercially available powdered coffee creamer in different pH environments.
Lysozyme is a commonly used enzyme for lysing Gram-positive bacteria. The comparatively simple structure and low cost make it a popular model in much current biological research.
In this application note, with the BeNano 90 Zeta, the particle size of lysozyme was measured and the molecular weight of lysozyme was calculated through the empirical Mark-Houwink equation. The study on the lysozyme denaturation at high temperature has been successfully carried out, by utilizing the precise temperature-control system of the BeNano 90 Zeta.
Size is not enough to ensure the consistency of abrasives and it is well known within the abrasives industry that the shape of the particles is equally as significant a parameter to control. The Bettersizer S3 Plus has proven to be able to characterize the size and shape of the abrasives simultaneously and provide much more information than conventional laser diffraction analyzers.
Milk powder is an important product from the processing of milk and it is widely used in the production of ice-cream, cultured milks and yogurts, chocolate, confectionery, bakery products, soups, and sauces.
The cement industry currently consumes 15% of the total energy used in the industrial sector globally. There are many technologies available which endeavor to reduce cement manufacturing costs by physical, chemical and logistical means.
