LIBS

Laser-Induced Breakdown Spectroscopy

Overview

The LIBS equipment investigates the analysis target with powerful laser pulses. In this process, the atoms on the surface of the analysis target absorb the laser energy and then release the energy in the form of light after several nanoseconds. The emitted light has a unique wavelength for each element, allowing us to determine whether a specific element is contained in the analysis target.

The SDT LIBS, a real-time non-destructive elemental analysis device, analyzes a wider variety of elements more simply and more quickly than the existing handheld methods at production sites.

Why SDT LIBS?

SDT LIBS performs real-time element analysis in production facilities 24 hours a day, 365 days a year, unlike traditional laboratory LIBS or handheld LIBS products.
The data collection module of SDT, NodeQ, connects to LIBS to command laser pulse surveys and read the wavelength values of light. SDT's industrial computer, ECN, immediately saves the data collected by NodeQ on-site and analyzes NodeQ's wavelength data to determine in real-time which elements are present in the subject of investigation. The data calculated by ECN is transmitted to the SDT Cloud, where it is accumulated in a database for real-time decision-making on-site and for future medium-term trend analysis and statistics.
Additionally, a camera is installed inside the LIBS equipment to simultaneously perform particle state verification using machine vision.

SDT LIBS performs real-time elemental analysis in production facilities autonomously 24 hours a day, 365 days a year, unlike traditional laboratory LIBS or handheld LIBS products.
The NodeQ, SDT's data collection module, connects to LIBS to command the laser pulse investigation and read the light wavelength values. SDT's industrial computer, the ECN, immediately stores the data collected by NodeQ onsite and analyzes the wavelength data from NodeQ to determine in real-time what elements are present in the target being examined. The data calculated by the ECN is transmitted to the SDT Cloud, where it is accumulated in a database for real-time decision-making and future medium to long-term trend analysis and statistics.
Additionally, a camera is installed inside the LIBS equipment, allowing for simultaneous confirmation of particle status using machine vision.

Customer success story

The concentration of ash residue left after combustion in a thermal power plant is an essential figure for managing combustion efficiency.

The customer of SDT, which operates Asia's largest biomass power plant, could not determine combustion efficiency in real-time as operators had to carry ash samples to the laboratory for component analysis over a period of 1 to 2 days.

To address this issue, the customer installed SDT LIBS to measure the elements of carbon, magnesium, silicon, calcium, iron, titanium, etc. in the ash, allowing them to detect problems occurring in the power generation process in real-time.
