For a deeper understanding of the processes and transformations that occur during the analysis of particles of powder materials and particles of suspensions

The acquisition of the BeVision M1 automatic image scanning system will complement the existing Mastersizer 3000 particle size analyzer with dry and wet dispersion modules and enable high-resolution analysis of particle morphology.<br /> The system is equipped with a microscope, programmable motorized stage, autofocus function and high resolution CMOS. The device can capture and recognize each individual particle, automatically combining the images into a large overview image.<br /> Features and advantages include a wide range of measurements: 1 - 10,000 μm, compliance with the ISO 9276-6 standard, high reproducibility of measurements, the presence of a stage with high positioning accuracy, the presence of 24 different parameters of particle size and shape.<br /> The BT-910 dry powder dispersion module is used to prepare samples before measurements. The module is designed for rapid dispersion of dry powder samples and subsequent analysis of particle size and shape using BeVision M1. This module can disperse both coarse and brittle materials under controlled conditions without any particle damage, providing an efficient and reproducible method of sample dispersion. It is suitable for various applications. Application occurs without additional reagents, with uniform application of the material on the glass slide.

Spectrophotometer CM-5 is designed to measure color by color parameters (L*, a*, b*) of all surfaces of solid materials, powders, pastes, liquids, granules, food products and ingredients, the surface of packaging materials, biopolymer films and gels, determining the freshness of products during storage. Kolov is an indicator of quality and safety, which is directly dependent on the quality of raw materials, recipe components and the type of technological factors influencing the food product.

The need for measurements is related to the variety of parameters that require analytical monitoring in the food laboratory, where color is the only directly obvious indicator of quality, and deserves due attention through objective and repeatable measurement of raw materials, production processes and the final product.<br /> These researches will contribute to the reduction of waste, allow to detect spoilage of products, control the quality of ingredients, and technological processes at all stages of production. This will allow to investigate the influence of storage conditions, thermal effects on the quality and safety of food products, will allow to control and adapt to prevent unwanted changes that lead to increased losses and waste. Depending on the sample, the CM-5 spectrophotometer can perform a variety of color measurement functions, measuring color samples by reflectance or transmittance with the ability to set tolerances for each measurement.
