FAQ
Q1: Kuv yuav ua li cas ntxuav cov tawv tawv seem ntawm lub raj mis?
A1: Yaug nrog dej distilled ua ntej. Rau cov organic residues, siv ethanol lossis acetone; rau inorganic deposits, soak hauv 10% HCl (tsis yog -HF-raws li) thiab yaug kom huv si. Tsis txhob txhuam txhuam los tiv thaiv iav nto thiab pob qij txha.
Q2: Puas yog av iav pob qij txha sib haum nrog tsis yog -quartz labware?
A2: Yog lawm, tsuav yog cov pob qij txha ua raws li tus qauv NS / GL (piv txwv li, NS 24/40). Xyuas kom ob daim yog huv si thiab maj mam greased (nrog silicone roj rau lub tshuab nqus tsev teeb) kom pom kev sealing.
Q3: Lub raj mis puas tuaj yeem rhaub ncaj qha rau ntawm lub phaj kub?
A3: Yog lawm, tab sis siv cov ceramic lossis hlau mesh ncoo los faib cov cua sov kom sib npaug. Tsis txhob siv hluav taws xob ncaj qha; rau cua sov ceev, siv lub preheated cua sov mantle tshaj quartz iav.
Q4: Puas yog lub raj mis leach ions rau hauv cov kev daws teeb meem?
A4: Tsis yog. High-purity quartz tsis yog -leaching, ua rau nws zoo tagnrho rau kev soj ntsuam kab (xws li, ICP- MS cov qauv) qhov twg hlau yuav tsum tau txo kom tsawg.
