FLBSIMS (Field Ionization Light Beam Scanning Imaging Mass Spectrometry) is a novel mass spectrometric imaging technique that has been developed in recent decades. It takes advantage of the fact that the overlapping signals of the ionizing light beam and mass spectrometer can be used to detect and image the same molecules in three dimensions. This technique has a wide range of applications in the field of analytical chemistry, such as proteomics, metabolomics, and imaging of biological molecules and tissues. In addition, it has been applied to the study of environmental contamination and human health toxicity.

The working principle of FLBSIMS is based on the principle of Field Ionization. In this technique, a light beam is directed towards the sample and the sample atoms or molecules are ionized by the light beam. The ionized particles are then accelerated by an electric field, which causes them to travel in the direction of the light beam. The ionized particles then travel along the light beam and are detected at the end of the light beam by the mass spectrometer.

The mass spectrometric imaging technique is based on the principle of Field Ionization Light Beam Scanning (FLBS). This technique is used to image the sample molecules in three dimensions. It is used to detect and identify the structure of a molecule at the level of individual atoms and molecules. In this technique, the light beam is directed towards the sample from different angles and a field ionization detector is used to detect and analyze the ionized particles as they travel along the light beam. By analyzing the trajectories and energies of the particles, the mass spectrometric imaging technique can be used to determine the structure of a molecule or an entire tissue.

In addition to its application in analytical chemistry, the FLBSIMS technique has also been applied for the study of environmental pollution and human health toxicity. In this technique, the light beam is used to detect and image the chemical pollutants in the environment and the tissue damage in human tissues. This technique is used to determine the concentrations of pollutants and trace elements in the environment, as well as to identify and analyze the effects of pollutants on human health.

In conclusion, the FLBSIMS technique is a powerful and versatile mass spectrometric imaging technique that has a range of applications. It is used to detect and image molecules in three dimensions, and it has also been used for the study of environmental contamination and human health toxicity. This technique is an important tool in the field of analytical chemistry and provides valuable information about the structure of molecules and their concentrations in the environment.
