摘要
The system (10) is used for performing a laser-induced breakdown spectroscopy (LIBS) analysis of at least two samples. The system (10) at least two spaced-apart sample receptacles (54) provided on the support member (52). Each location to be analyzed on the samples (12) is successively made coincident with a target point (T) at which a high power laser beam pulse is focused. The system (10) comprises a positioning mechanism (60) for selectively pivoting and locking in position the support member (52) around its medial axis (M) and for offsetting the support member (52) in at least one direction and locking it in position. A spectral analysis of a radiation emitted by a plasma produced by the laser beam pulse on the sample (12) is performed and the data are analyzed by a computer (40). The computer (40) also controls the operation of the system (10).
