At Gillson Sciences, we apply advanced particle counting technologies to deliver accurate, reproducible data for product quality, compliance, and research. Our capabilities include Light Obscuration and Light Scattering, Optical Microscopy, and Flow Imaging, each offering unique advantages depending on the material, particle characteristics, and regulatory requirements. Ideal for high-throughput, precise size distribution analysis in liquids.Light obscuration and light scattering are precise analytical methods for measuring and sizing particles in liquid suspensions. As particles pass between a laser light source and a detector, they block or scatter light. The detector measures the change in light intensity and processes the data to determine particle quantity and size distribution. Our volumetric liquid particle counters analyze the entire liquid stream, measuring particles from 0.2 μm to 1,000 μm in up to 1,024 size channels, providing detailed and reliable results. Best for visual identification, morphology assessment, and differentiating particle types. Optical microscopy involves visually examining particulate matter collected on a filtration membrane to identify and quantify individual particles. This method offers direct observation of particle size, shape, and distribution at working ranges starting from 5 μm and larger. It is especially useful for differentiating particle types and evaluating surface morphology. Recommended for detailed shape analysis, biologics, and protein-based formulations. Flow imaging uses digital imaging technology to measure particles in a moving fluid stream. This method provides precise analysis of size, morphology, shape characteristics, grayscale or color attributes, and statistical population distribution. With a working range starting from 2 μm, flow imaging is particularly effective for analyzing biologics and protein-based products. High-resolution images capture detailed particle features, ensuring accurate classification and dependable results.
