ʻO Laser-Induced Breakdown Spectroscopy (LIBS), i ʻike ʻia ʻo Laser-Induced Plasma Spectroscopy (LIPS), he ʻenehana ʻike wikiwiki.
Ma ka nānā ʻana i ka pulse laser me ka nui o ka ikehu kiʻekiʻe ma luna o ka ʻili o ka mea i hoʻāʻo ʻia, hana ʻia ka plasma e ka ablation excitation, a laila ma ka nānā ʻana i nā laina spectral hiʻohiʻona i hoʻomālamalama ʻia e ka neʻe ʻana o ka ikehu electron o nā ʻāpana i loko o ka plasma. hiki ke loaʻa nā ʻano a me nā ʻike kikoʻī o nā mea i loko o ka hāpana.
Hoʻohālikelike ʻia me nā ʻano hana ʻike ʻeleʻele i hoʻohana mau 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 Flugometer ), Spark Discharge Optical Emission Spectroscopy, SD-OES) Pēlā nō, ʻaʻole koi ʻo LIBS i ka hoʻomākaukau laʻana, hiki ke ʻike i nā mea he nui i ka manawa like, hiki ke ʻike i nā mokuʻāina paʻa, wai, a me ke kinoea, a hiki ke hoʻāʻo ʻia ma kahi mamao a ma ka pūnaewele.
No laila, mai ka hiki ʻana mai o ka ʻenehana LIBS i ka makahiki 1963, ua huki ia i ka manaʻo ākea o nā mea noiʻi ma nā ʻāina like ʻole.Ua hōʻike pinepine ʻia ka hiki ke ʻike o ka ʻenehana LIBS ma nā ʻōnaehana kikowaena.Eia nō naʻe, ma ke kahua kahua a i ʻole ke kūlana maoli o ka kahua ʻoihana, pono ka ʻenehana LIBS e kau i nā koi kiʻekiʻe.
No ka laʻana, ʻaʻohe mana o ka ʻōnaehana LIBS ma lalo o ka ʻenehana optical laboratory i kekahi mau hihia ke paʻakikī ke hoʻohālikelike a lawe ʻana i nā laʻana ma muli o nā kemika weliweli, nā mea radioactive a i ʻole nā kumu ʻē aʻe, a i ʻole ka paʻakikī o ka hoʻohana ʻana i nā lako analytical nui ma kahi ākea. .
No kekahi mau kahua kiko'ī, e like me ka archaeology, ka ʻimi mineral, nā kahua hana ʻenehana, ʻoi aku ka nui o ka ʻike ʻana i ka manawa maoli, a me ka pono o ka miniaturized, portable analytical lako.
No laila, i mea e hoʻokō ai i nā pono o ka hana kahua a me ka hana ʻenehana i ka ʻike pūnaewele a me nā hiʻohiʻona hiʻohiʻona diversification, ka portability o nā mea hana, anti-harsh environment hiki a me nā ʻano hou ʻē aʻe ua lilo i mea hou a kiʻekiʻe aʻe no ka ʻenehana LIBS i nā noi ʻoihana, LIBS portable. ua hoʻokumu ʻia, a ua hopohopo nui ʻia e nā mea noiʻi ma nā ʻāina like ʻole.
