DragonFly LIBS Elemental Analysis System

DragonFlyIt is the only derivative company of the European Engineering Technology Center (CEITEC)LightigoThe product model launched by the company, parallel to FireFly, aims to achieve the strongest universality by supporting expansion and research-oriented design, allowing users to fully enjoy the strongest advantages of LIBS technology

Dragonfly can achieve excellent detection results for samples that are usually difficult to detect, such as C element in steel, F element in geotechnical materials, Cl element in concrete materials, Li element in batteries, etc.

DragonFlyFor flexible and easily expandable modular design, it features a vacuum reaction chamber with automatic continuous control ranging from 1 to 1300 mbar and automatic laser pulse wavelength switching function; In addition, a UV vacuum module can be optionally selected to solve the special situation of multiple spectral lines interfering with each other in the visible light region. DragonFly supports flexible customization, such as dual excitation, multi excitation schemes, and multi optical path acquisition.

LIBSTechnical principles and advantages

DragonFlyApplication case:

1. LIBSThe application of technology in cancer detection:

CEITECThe Lightigo research team at Brno University of Technology is conducting research on skin cancer detection using LIBS technology - the elemental composition of cancerous cells is different from that of normal cells, so LIBS technology is used to detect the elemental characteristics of tumor tissue for medical diagnosis.

2020On January 24th of the year, Czech radio released an interview with the Lightigo team at the Laser Spectroscopy Laboratory of Brno University of Technology. Pavel Po, the project leader of LightigořízkaSpeaking of: "LIBS measurement can obtain a series of element distribution images, helping pathologists to diagnose as soon as possible. Large tumors are easy to detect, but LIBS technology will be very useful for small satellite tumors that are difficult to detect

2. Mapping analysis of nano silver particle distribution in the roots of broad bean seedlings using dual excitation LIBS technology

Roots play an important role in providing nutrients to plants and protecting them from excessive metal ion toxicity. However, the difficulty of elemental analysis in roots is much greater than that in stem tissues, due to the fact that roots are usually much smaller than stems and shoots; The dry matter content is much lower, which brings great inconvenience to sample cutting; Usually, the relative content of the elements to be analyzed is relatively low; How to maintain the structural shape of soft and juicy samples to obtain the correct distribution of elements is also a challenge.

LightigoIn response to the above challenges, a successful exploration was conducted in this case by applying dual excitation LIBS technology to map and analyze nano silver particles (diameter 21.7 ± 2.3 nm) in the roots of broad bean seedlings. The goal is to detect elements in plant tissues in their natural state, achieving high mapping resolution while ensuring detection sensitivity. This is also the first attempt in the entire LIBS field to investigate the distribution of nanoparticles in plant roots.

Experimental conclusion:

LIBSFast technical testing speed; Even for roots with a diameter of only 2mm, mapping analysis can be performed on the distribution of metal ions and metal nanoparticles in their cross-section, with detection accuracy and image resolution sufficient to meet experimental requirements. By applying dual excitation technology, the mapping resolution can reach 50 μ m, which is sufficient to distinguish the distribution characteristics of elements in the root epidermis, cortex, and central column.

In addition, a short processing time of 7 days can detect the results, indicating that LIBS element mapping is also an effective experimental method for detecting element distribution in plants under natural environment and nutrient conditions. Therefore, it will be useful in the fields of plant physiology and environmental toxicology.
