Method and Instrumentation for Determining a Physical Property of a Particle

Previous models for particle analysis have had difficulty with low-density applications. Particle properties, particularly in particles with varying absorptive properties or chemical compositions, can be tough to determine accurately. These properties are critical for many scientific applications, including the detection of biological or chemical agents. Without precise identification of a particle's physical properties, the efficiency and accuracy of these applications can be jeopardized. The main problem with current approaches is their lack of sensitivity when dealing with low particle density scenarios. For instance, in detecting biological or chemical agents, high sensitivity is required to ensure precision. Inadequate sensitivity leads to inaccurate results, leaving room for potential errors or oversights. This significant concern is especially paramount in scenarios like healthcare and defense sectors.

Technology Description

The invention is a technology that determines physical properties or classifies particles based on these properties by evaluating the scattered light profile from a single particle. It can analyze particles including those with chemical structures that vibrate as a function of their properties. Such properties could be absorptive properties or chemical composition. The process involves detecting a scattered light spectrum and identifying at least two anomalous dispersive regions from it. The physical properties of the particle can be determined by taking these regions into account. The technology is highly differentiated because of its ability to efficiently and accurately handle low-density particle applications. Its sensitivity is particularly beneficial for detecting biological and chemical agents because it can identify physical properties even in particles with lower density. The detection approach employing anomalous dispersive region identification from a scattered light spectrum provides specific and detailed data to facilitate precise determination.
