Authored by: Teagan Horan, Applications Scientist, SiMPore and Peng Miao, Applications Scientist, HORIBA Instruments Inc. Introduction USP788 is an accepted method by which to test parenteral drug products for the presence of subvisible particles 10 µm and larger. Method I utilizes light obscuration to detect and measure levels of these particles. When samples exceed the […]

At SiMPore, we provide the analytical tools for the consumer beverage industry to uncover answers and validate solutions when tackling the microplastics challenge in beverage products. SiMPore Filter Disks, comprising silicon nanomembrane technology feature precision-patterned, consistent pore geometry, enabling improved particle capture and analysis methodologies over other available filter options on the market. For this […]

As consumers become increasingly aware of the microplastic pollution problem, many are asking a critical question: does the pitcher filter on their kitchen counter actually protect them? Microplastic filtration — the process of physically removing microscopic plastic particles from water — has become a key consideration for health-conscious households. Yet until now, there has been […]

Choosing the right TEM window grid is an important step in achieving reliable, high-quality imaging. Researchers must often balance resolution, mechanical durability, and compatibility with existing instrumentation when making a selection. In this post, we outline the key factors to consider when selecting a TEM window grid and explain how each decision can impact performance […]

Introduction Many laboratories are newly interested in capturing and analyzing microplastics from a variety of samples, and need to acquire and set up the necessary apparatus to do so. This guide outlines the essentials for setting up and using SiMPore Filter Disks with the required filtration equipment. Using SiMPore Filter Disks Figure 1 below shows […]

Introduction Analytical laboratories are constantly faced with balancing the costs and benefits of processing time,nconsumables cost, and the quality of collected data. When analyzing samples for microplastics, practitioners must consider laborious sample preparation, instrument data collection time, data analysis, and reporting time. This study compares two membranes – a commonly used 20 µm gold-coated polycarbonate […]
