Dynamic image analysis (DIA) is a digital method of particle characterization that enables a researcher to identify the shape, size, and number of particles in a sample. Due to its high accuracy and reproducibility, DIA is a widely used image analysis method across most industries to support quality control, compliance, and research applications. One such application is the analysis of fiber particles. Because fiber particles are used as raw materials in many processes, scientists must analyze them to ensure their properties are suitable for their intended purposes. Therefore, this blog post will look at how vital dynamic image analysis is for properly analyzing fiber particles.
Is Dynamic Image Analysis Essential for Proper Fiber Particle Analysis?
Fiber particles are so widely used it’s imperative to be able to analyze them and their properties accurately. Typically, fiber particles are used to enhance a product’s productivity and quality while minimizing waste. However, one of the main challenges of analyzing fiber particles is that they cannot be measured in the standard way, which is to measure particle sizes in units of equivalent spherical diameter. This measurement method will not work for fiber particles because they are not round or spherical but have irregular shapes that can change.
Dynamic image analysis is ideal for measuring the characteristics of fiber particles to offer a solution to spherical measurements. Fiber models have been designed to accurately obtain information about individual fiber particles, which includes their size, length, width, aspect ratio, and opacity.
A Case Study of Measuring Fiber Particles
In this section, we provide videos highlighting why size-only (spherical) measurements are unsuitable for fiber particles. The case study will also discuss how researchers can obtain accurate measurements of different types of fiber particles through dynamic image analysis.
The first video is about how measuring fiber particles with size-only measuring instruments can lead to inaccurate results, which can be problematic for their intended applications.
The second video also details how direct measuring techniques, such as dynamic image analysis, are the ideal solution for irregular particles, such as fibers.
Vision Analytical and Particle Analysis
Vision Analytical are experts in particle size, shape, concentration, and classification, offering a range of instruments and systems for particle analysis. Our image analysis equipment was designed to complement size-only particle measurement techniques. It can measure a range of properties that are vital to those using fiber particles in their applications.
Through our Particle Insight range, we offer a class-leading dynamic image analyzer that focuses on particle shape measurements, not just particle size. As mentioned throughout this blog, fiber particles cannot be measured as spherical objects because they are of irregular shapes. Incorrect measurement can have damaging impacts on applications and processes; therefore, dynamic image analysis is essential for correctly measuring fiber particles. The Particle Insight range includes the Pi Sentinel PRO, a fully automated system offering accuracy, speed, and ease of use for particle analysis.
