Five edible salt products from Australia, Bolivia, France, and South Korea were dissolved in water and a tiny volume of each solution was dropped on the solid substrate, that is, a miniaturized salt pond. After being dried, the residual salt crystals distributed still inhomogeneously, but the homogeneity could be significantly improved in comparison with that from typical drop-and-dry methods. The ALADS scheme was applied to extract three precise measurements from 9798 single-shot LIBS spectra covering the entire salt pond. The measurements obtained by ALADS were found to agree well with one another regardless of the inhomogeneous distribution of salt crystals. As a result, the measurement precision was proved remarkably. Limits of detection for K, Mg, Ca, and S were estimated to be 0.64, 1.7, 14, and 530\u2005mg\/kg, respectively, which are enough to analyze those elements contained in salts typically at the level of 100 parts per million (ppm) to \u223c3\u2005wt% for the purpose of salt quality assessment.<\/jats:p>","DOI":"10.1177\/00037028231206195","type":"journal-article","created":{"date-parts":[[2023,10,16]],"date-time":"2023-10-16T18:47:41Z","timestamp":1697482061000},"page":"1351-1361","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Highly Precise Laser-Induced Breakdown Spectroscopy Analysis of Major Mineral Nutrients in Edible Salts Using Miniaturized Salt Ponds and Alternating Laser-Ablation Data Sampling"],"prefix":"10.1177","volume":"77","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3255-4054","authenticated-orcid":false,"given":"Jeong","family":"Park","sequence":"first","affiliation":[{"name":"Department of Chemistry, Mokpo National University, Jeonnam, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Song-Hee","family":"Han","sequence":"additional","affiliation":[{"name":"Division of Navigation Science, Mokpo National Maritime University, Jeonnam, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang-Ho","family":"Nam","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Mokpo National University, Jeonnam, Republic of Korea"},{"name":"Plasma Spectroscopy Analysis Center, Mokpo National University, Jeonnam, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5418-2434","authenticated-orcid":false,"given":"Yonghoon","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Mokpo National University, Jeonnam, Republic of Korea"},{"name":"Plasma Spectroscopy Analysis Center, Mokpo National University, Jeonnam, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,10,16]]},"reference":[{"key":"bibr1-00037028231206195","volume-title":"Salt: A World History","author":"Kurlansky M.","year":"2002"},{"key":"bibr2-00037028231206195","doi-asserted-by":"publisher","DOI":"10.1111\/j.1745-459X.2010.00317.x"},{"key":"bibr3-00037028231206195","doi-asserted-by":"publisher","DOI":"10.4315\/0362-028X-61.7.891"},{"key":"bibr4-00037028231206195","doi-asserted-by":"publisher","DOI":"10.1021\/jf202204d"},{"key":"bibr5-00037028231206195","doi-asserted-by":"publisher","DOI":"10.1177\/0003702817691288"},{"key":"bibr6-00037028231206195","doi-asserted-by":"publisher","DOI":"10.1366\/11-06379"},{"key":"bibr7-00037028231206195","doi-asserted-by":"publisher","DOI":"10.1002\/bkcs.10043"},{"key":"bibr8-00037028231206195","doi-asserted-by":"publisher","DOI":"10.1177\/00037028221091581"},{"key":"bibr9-00037028231206195","doi-asserted-by":"publisher","DOI":"10.1016\/j.sab.2021.106088"},{"key":"bibr10-00037028231206195","doi-asserted-by":"publisher","DOI":"10.1016\/j.sab.2016.02.019"},{"key":"bibr11-00037028231206195","doi-asserted-by":"publisher","DOI":"10.1177\/0003702817697337"},{"key":"bibr12-00037028231206195","doi-asserted-by":"publisher","DOI":"10.3892\/mmr.2016.5407"},{"key":"bibr13-00037028231206195","doi-asserted-by":"publisher","DOI":"10.1081\/IPH-120024505"},{"key":"bibr14-00037028231206195","doi-asserted-by":"publisher","DOI":"10.1016\/j.biocel.2018.07.010"},{"key":"bibr15-00037028231206195","doi-asserted-by":"publisher","DOI":"10.1007\/s10661-007-9975-9"},{"issue":"1","key":"bibr16-00037028231206195","doi-asserted-by":"crossref","first-page":"41","DOI":"10.4103\/2277-9183.102376","volume":"1","author":"Pourgheysari H.","year":"2012","journal-title":"Int.
