Topsizer Plus Laser Particle Size Analyzer Introduction
Topsizer Plus maintains the advantages of TopSizer, such as wide range, good repeatability, high resolution, strong real test performance and high intelligence, by further improving optical design, hardware and inversion algorithm, Topsizer Plus expands its test scope and actual test performance, it can be widely used in various fields of modern industry such as chemical industry, machinery, building materials, energy, pharmaceuticals and so on.
In many industries, such as lithium-ion battery, pharmaceuticals, hydrology and fine chemicals, many users choose Omec laser particle size analyzers, especially TopSizer, in addition to the trust for Omec brand and technology, but also because it comes from the product technology and quality management system of Malvern Panalytical, the instrument test results have excellent accuracy, authenticity and sensitivity.
Topsizer series products ensure that the test results and analysis capabilities are consistent with the gold standards of domestic & foreign and upstream & downstream industries, whether it is raw materials, preparations or positive and negative materials for lithium ion batteries. This not only saves the time and cost of method development and method transfer for users, but also avoids the economic losses and risks caused by inaccurate particle size detection. Whether in R&D, process control or quality control, it can bring real value to users.
