Dukurikije imbonerahamwe ya 3 na 4, ubwiyongere bwa Cu, Pb, Cd, Ni na Cr mu gipimo cy'amazi yo hejuru ni 91.2% ~ 105.5%, kandi itandukaniro risanzwe ry'igipimo gisanzwe ni 1.5% ~ 2.6% ku bipimo 7 bihuriranye.
3 Umwanzuro
Dukurikije ibisabwa na "Ibipimo ngenderwaho by'Ubuziranenge bw'Ibidukikije by'Amazi yo hejuru" (GB 3838-2002), ingano ya Cu, Pb, Cd na Ni mu mazi yo hejuru yujuje ibipimo ngenderwaho by'amazi yo mu cyiciro cya kabiri. Kuri iyi nshuro, spectrophotometer ya WFX-220A yakoreshejwe mu kumenya Cu, Pb, Cd, Ni na Cr hashingiwe kuri HJ 1453-2026 "Kumenya Cu, Pb, Cd, Ni na Cr mu bwiza bw'amazi hakoreshejwe Graphite Furnace Atomic Absorption Spectrophotometry", kandi ibisubizo by'urwego ntarengwa rwo kumenya, ukuri kw'icyitegererezo n'ubuziranenge byari bishimishije.
WFX-220A spectrophotometer yo gufata atome ifite ubushobozi bwo kumva neza, gukora neza no gukoresha ibintu bitandukanye. Ikintu gikomeye cyane ni urwego rwo hejuru rw’imikorere, umuriro n’itanura rya grafiti bishobora gukora switching yikora rimwe gusa, hamwe n’uburyo bwo kugenzura imikorere y’amazi neza cyane hamwe na porogaramu z’ubwenge zifite ububiko bw’amakuru bw’abahanga, imikorere yoroshye kandi ikora neza. Muri icyo gihe, igikoresho gikoresha igishushanyo mbonera cya modular cyo kubungabunga buri munsi, kandi gifite uburyo bwinshi bwo kwirinda no kurinda ubushyuhe buhuza porogaramu na hardware kugira ngo imikorere idahinduka. Byongeye kandi, gishyigikira uburyo bwo gukoresha umuriro mu bushyuhe bwinshi, uburyo bwa hydride n’uburyo butandukanye bwo kongeramo ibikoresho bya autosampler, bushobora guhaza neza isesengura ry’icyuma mu kurengera ibidukikije, ibiribwa n’imiti n’ibindi bikorwa.
