USA: Particle Analysis Spectro Patents Novel Particle Analysis Technology

Spectro Scientific has been awarded a U.S. patent to extend the Lasernet Fines particle analysis technology with new capabilities to size and count ferrous particles and measure total ferrous content by weight. This technology is used in Spectro Scientific’s Lasernet 230 particle analyzer, formerly named the Lasernet Fines (LNF) Q230.

Chelmsford/USA — According to the company, the patented technology enables the Lasernet 230 instrument to accurately size and count ferrous particles as small as 25 microns in size and measure total ferrous content below 10 ppm. These developments enable the device to perform these two measurements in one test.

The core of the technology is two sets of magnetic coils wound with high precision to achieve the desired sensitivity level. A set of proprietary ferrous particle standards is supplied with the instrument for performance verification. According to the company, the new capability makes Lasernet 230 the most comprehensive analyzer for wear particle testing in lubricants used in rotating machines within industrial and power generation plants, such as gearboxes and turbines.

The Lasernet 200 Series uses Lasernet Fines particle analysis technology were jointly developed by the Naval Research Lab and Lockheed Martin Corporation and exclusively licensed to Spectro Scientific. The technology employs an Infrared laser, a patented flow cell, and a high-speed CCD camera to capture particle images. The software uses a neural network algorithm to automatically classify particles into cutting wear, fatigue wear, sliding wear, non-metallic particles, water droplets and other types. It can measure oil samples with up to 10 million particles per milliliter without dilution.
