ʻO ka Laser-Induced Breakdown Spectroscopy (LIBS), i ʻike ʻia hoʻi ʻo Laser-Induced Plasma Spectroscopy (LIPS), he ʻenehana ʻike spectral wikiwiki.
Ma ka hoʻopololei ʻana i ka pulse laser me ka nui o ka ikehu ma luna o ka ʻili o ka pahuhopu o ka hāpana i hoʻāʻo ʻia, hoʻopuka ʻia ka plasma e ka hoʻonāukiuki ablation, a laila ma ka nānā ʻana i nā laina spectral hiʻohiʻona i hoʻomālamalama ʻia e ka hoʻololi pae ikehu electron o nā ʻāpana i loko o ka plasma, hiki ke loaʻa nā ʻano a me ka ʻike o nā mea i loko o ka hāpana.
Ke hoʻohālikelike ʻia me nā ʻano ʻike mea i hoʻohana pinepine ʻia i kēia manawa, e like me Inductively Coupled PlasmaOptical Emission Spectrometry (ICP-OES), 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) Pēlā nō, ʻaʻole koi ʻo LIBS i ka hoʻomākaukau ʻana i ka laʻana, hiki ke ʻike i nā mea he nui i ka manawa like, hiki ke ʻike i nā kūlana paʻa, wai, a me ke kinoea, a hiki ke hoʻāʻo ʻia ma kahi mamao a ma ka pūnaewele.
No laila, mai ka hoʻomaka ʻana o ka ʻenehana LIBS i ka makahiki 1963, ua huki ia i ka manaʻo nui o nā mea noiʻi ma nā ʻāina like ʻole. Ua hōʻike pinepine ʻia nā hiki ke ʻike o ka ʻenehana LIBS ma nā hoʻonohonoho hale hana. Eia nō naʻe, ma ke kahua a i ʻole ke kūlana maoli o ke kahua ʻoihana, pono ka ʻenehana LIBS e hoʻokau i nā koi kiʻekiʻe.
Eia kekahi laʻana, ʻaʻohe mana o ka ʻōnaehana LIBS ma lalo o ka paepae optical laboratory i kekahi mau hihia ke paʻakikī ke kau i ka laʻana a i ʻole ka lawe ʻana i nā laʻana ma muli o nā kemika weliweli, nā mea radioactive a i ʻole nā kumu ʻē aʻe, a i ʻole ke paʻakikī ke hoʻohana i nā lako loiloi nui ma kahi ākea haiki.
No kekahi mau kahua kikoʻī, e like me ke kahua ʻeli honua, ka ʻimi ʻana i nā minerala, nā wahi hana ʻoihana, ʻoi aku ka nui o ka ʻike manawa maoli, a me ka pono no nā lako hana loiloi liʻiliʻi a lawe lima.
No laila, i mea e hoʻokō ai i nā pono o nā hana kahua a me ka ʻike ʻana i ka hana ʻoihana ma ka pūnaewele a me ka hoʻololi ʻana i nā ʻano laʻana, ka hiki ke lawe ʻia o nā lako, ka hiki ke kūʻē i ke kaiapuni ʻino a me nā ʻano hou ʻē aʻe ua lilo i mau koi hou a kiʻekiʻe no ka ʻenehana LIBS i nā noi ʻoihana, ua hoʻomaka ʻia nā LIBS lawe lima, a ua hopohopo nui ʻia e nā mea noiʻi ma nā ʻāina like ʻole.
