摘要

Gallstones, which are frequently asymptomatic, are a widespread issue worldwide. Gallstones can occur for a variety of reasons, some of which may be related to food, particularly eating too much meat and fats. The study aimed to identify the components of gallstone formation and their concentration ratios, as the chemical composition of gallstones in 50 patients (35 females and 15 males) was examined. This study focuses on the analysis of the accumulated elements that lead to the growth of human gallstones and determines the concentration ratio of each element using LIBS and ICP-MS techniques. Using LIBS and ICP-MS techniques, five common metal elements (S, Al, Ca, Fe, and Ni) were identified as contributing to the growth and formation of human gallstones. The concentrations of the detected metals in the samples were then determined using calibration curves for both techniques. From the results obtained, it was clear that laser-induced breakdown spectroscopy (LIBS) has the potential to determine the concentrations of metals in gallstones. However, the correlation coefficient (R²) of ICP-MS measurements was higher, indicating superior accuracy. The excellent accuracy of ICP-MS can enhance the stability and precision of LIBS.
