Nūhou - Nā ʻenehana ʻike maʻemaʻe no nā metala maʻemaʻe kiʻekiʻe

Eia kahi loiloi piha o nā ʻenehana hou loa, ka pololei, nā kumukūʻai, a me nā hiʻohiʻona noi:

I. Nā ʻenehana ʻike hou loa

?Kumumanaʻo‌: Hoʻohana i ka tandem mass spectrometry (MS/MS) e hoʻopau i ka matrix interference, i hui pū ʻia me ka pretreatment i hoʻomaikaʻi ʻia (e laʻa, ka ʻai ʻana o ka waikawa a i ʻole ka hoʻoheheʻe ʻana o ka microwave), e hiki ai ke ʻike i nā ʻano o nā mea haumia metala a me metalloid ma ka pae ppb‌
?Pololei‌: Ka palena ʻike haʻahaʻa e like me ‌0.1 ppb‌, kūpono no nā metala maʻemaʻe loa (≥99.999% maʻemaʻe)‌
?Kumukūʻai‌: Ke kumukūʻai lako kiʻekiʻe (‌~285,000–285,000–714,000 USD‌), me nā koi mālama a me ka hana koi

?Kumumanaʻo‌: Ke ana i nā mea haumia ma ka nānā ʻana i nā spectra hoʻokuʻu kikoʻī o nā element i hana ʻia e ka hoʻonāukiuki plasma.
?Pololei‌: ʻIke i nā haumia pae ppm me kahi laulā linear ākea (5-6 mau kauoha o ka nui), ʻoiai hiki ke hana i ka hoʻopilikia matrix.
?Kumukūʻai‌: Kumukūʻai lako kūpono (‌~143,000–143,000–286,000 USD‌), kūpono no nā metala maʻemaʻe kiʻekiʻe maʻamau (99.9%–99.99% maʻemaʻe) i ka hoʻāʻo ʻana o ka ʻāpana.

?Kumumanaʻo‌: Hoʻopili pololei i nā ʻili laʻana paʻa e pale aku i ka haumia o ka hopena, e hiki ai ke nānā i ka nui o ka isotope‌.
?Pololei‌: Nā palena ʻike e hōʻea ana i ‌pae ppt‌, i hoʻolālā ʻia no nā metala semiconductor-grade ultra-pure (≥99.9999% maʻemaʻe).
?Kumukūʻai‌: Kiʻekiʻe loa (‌> $714,000 USD‌), i kaupalena ʻia i nā keʻena hoʻokolohua holomua‌.

?Kumumanaʻo‌: Hoʻopili i nā kūlana kemika o ka ʻili e ʻike i nā papa oxide a i ʻole nā pae haumia‌78.
?Pololei‌: Hoʻonā hohonu nanoscale akā ua kaupalena ʻia i ka nānā ʻana i ka ʻili.
?Kumukūʻai‌: Kiʻekiʻe (‌~$429,000 USD‌), me ka mālama paʻakikī.

II. Nā Hoʻonā ʻIke i Manaʻo ʻia

Ma muli o ke ʻano metala, ka pae maʻemaʻe, a me ke kālā, ua manaʻo ʻia nā hui pū ʻana penei:

?ʻenehana‌: ICP-MS/MS + GD-MS‌14
?Nā Pōmaikaʻi‌: Uhi i nā mea haumia liʻiliʻi a me ka nānā ʻana i ka isotope me ka pololei loa.
?Nā noi‌: Nā mea semiconductor, nā pahuhopu sputtering.

?ʻenehana‌: ICP-OES + Titration Kemika‌24
?Nā Pōmaikaʻi‌: Kūpono ke kumukūʻai (‌huina ~$214,000 USD‌), kākoʻo i ka ʻike wikiwiki ʻana i nā mea he nui.
?Nā noi‌: Kini maʻemaʻe kiʻekiʻe ʻoihana, keleawe, a pēlā aku.

?ʻenehana‌: XRF + Fire Assay‌68
?Nā Pōmaikaʻi‌: Kānana ʻole luku (XRF) i hui pū ʻia me ka hōʻoia kemika pololei kiʻekiʻe; kumukūʻai holoʻokoʻa ‌~71,000–71,000–143,000 USD?
?Nā noi‌: Nā mea hoʻonani, bullion, a i ʻole nā hiʻohiʻona e pono ai ka pono o ka laʻana.

?ʻenehana‌: Titration Kemika + Conductivity/Thermal Analysis‌24
?Nā Pōmaikaʻi‌: Huina kumukūʻai ‌< $29,000 USD‌, kūpono no nā SME a i ʻole ka nānā mua ʻana‌.
?Nā noi‌: Nānā ʻana i nā mea maka a i ʻole ka kaohi maikaʻi ma kahi.

III. Ke Alakaʻi Hoʻohālikelike a me ke Koho ʻana i ka ʻenehana

ʻenehana	Pololei (Palena ʻIke)	Kumukūʻai (Lako + Mālama)	Nā noi
ICP-MS/MS	0.1 ppb	Kiʻekiʻe Loa (>$428,000 USD)	Ka nānā ʻana i ke kaha metala maʻemaʻe loa‌15
GD-MS	0.01 ppt	ʻOi loa (>$714,000 USD)	ʻIke isotope pae semiconductor‌48
ICP-OES	1 ppm	Kaulike (143,000–143,000–286,000 USD)	Hoʻāʻo pūʻulu no nā metala maʻamau‌56
XRF	100 ppm	Waena (71,000–71,000–143,000 USD)	Pale metala makamae ʻaʻole luku‌68
Titration Kemika	0.1%	Haʻahaʻa (<$14,000 USD)	Ka loiloi helu haʻahaʻa kumukūʻai‌24

Hōʻuluʻulu Manaʻo

?ʻO ke kūlana koʻikoʻi ma ka pololei‌: ICP-MS/MS a i ʻole GD-MS no nā metala maʻemaʻe loa, e koi ana i nā kālā koʻikoʻi‌.
?Ka Hoʻokō Kūpono o ke Kumukūʻai‌: ICP-OES i hui pū ʻia me nā ʻano kemika no nā noi ʻoihana maʻamau‌.
?Nā Pono ʻAʻole e Hoʻopau‌: Hoʻāʻo ahi XRF + no nā metala makamae.
?Nā Palena Hoʻolālā Kālā‌: ʻO ka titration kemika i hui pū ʻia me ka loiloi conductivity/thermal no nā SME‌
