Ko te Laser-Induced Breakdown Spectroscopy (LIBS), e mōhiotia ana ko te Laser-Induced Plasma Spectroscopy (LIPS), he tikanga kimi hihi tere.
Mā te arotahi i te pā o te taiaho me te kiato kaha teitei ki te mata o te ūnga o te tauira i whakamatautauria, ka whakaputaina te parāuma mā te whakaohooho ablation, kātahi ka tātari i ngā rārangi hihinga āhuatanga e tukuna ana e te whakawhiti taumata kaha irahiko o ngā matūriki i roto i te parāuma, ka taea te whiwhi i ngā momo me ngā mōhiohio ihirangi o ngā huānga kei roto i te tauira.
Ki te whakatauritea ki ngā tikanga kimi huānga e whakamahia whānuitia ana i tēnei wā, pērā i te Inductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), te Inductively coupled Plasmaoptical mass spectrometry (Inductively Coupled PlasmaOptical Emission Spectrometry) Coupled PlasmaMass Spectrometer (ICP-MS), X-ray Fluorescence (XRF), Spark Discharge Optical Emission Spectroscopy, SD-OES). Waihoki, kāore e hiahiatia he tauira mō te LIBS, ka taea te kimi i ngā huānga maha i te wā kotahi, ka taea te kimi i ngā āhua totoka, wai, me te hau, ā, ka taea te whakamātautau mamao me te ipurangi.
Nō reira, mai i te taenga mai o te hangarau LIBS i te tau 1963, kua aro nui mai ngā kairangahau o ngā whenua maha ki tēnei hangarau. He maha ngā wā kua whakaaturia te kaha o te hangarau LIBS ki te kimi i ngā matū i roto i ngā taiwhanga. Heoi, i roto i te taiao parae, i te āhua tūturu rānei o te papa ahumahi, me whakatakoto e te hangarau LIBS ngā whakaritenga teitei ake.
Hei tauira, kāore he mana o te pūnaha LIBS i raro i te tūāpapa whatu taiwhanga i ētahi wā ina uaua ki te tango tauira, ki te kawe rānei i ngā tauira nā ngā matū kino, ngā matū irahiko, ētahi atu take rānei, ina uaua rānei ki te whakamahi i ngā taputapu tātari nui i roto i te wāhi whaiti.
Mō ētahi mara motuhake, pērā i te whaipara tangata o te mara, te tūhuratanga kohuke, ngā wāhi whakaputa ahumahi, he mea nui ake te kimi i te wā-tūturu, me te hiahia hoki ki ngā taputapu tātari iti, kawe.
Nō reira, kia tutuki ai ngā hiahia o ngā mahi mara me te hanga ahumahi, te kimi ipurangi me te whakanui i ngā āhuatanga tauira, ko te kawe i ngā taputapu, te kaha ki te ārai i te taiao kino me ētahi atu āhuatanga hou kua noho hei whakaritenga hou, ā, he nui ake ngā whakaritenga mō te hangarau LIBS i roto i ngā tono ahumahi, i puta mai ai ngā LIBS kawe, ā, kua whānuitia te aro o ngā kairangahau i ngā whenua rerekē.
