Instant identification and characterization of samples by the dynamic combination of laser ablation and mathematical algorithms.

摘要

Identification and instantaneous characterization of samples without pretreatment by dynamic combination of laser ablation and mathematical algorithms. # The method is based on analysis of a single laser pulse which a sample spectrum is compared with a database is obtained spectral dynamics using a neural network that can handle a large number of data in a very short with 100% sensitivity and specificity time. # identification and characterization technique is fast, direct and allows the correlation of analytical data with organoleptic properties or quality and the determination of substances, compounds contaminants, pathogens or bioactive present in samples in any state of matter without any prior preparation.
