The graphite tube, the heart of the graphite furnace, plays a vital role in the overall stability of an analysis. In order to assure stable analytical conditions from one atomization cycle to the next, and from graphite tube to graphite tube, all graphite parts - contacts, tubes and platforms - must be subject to strict quality control by both the instrument manufacturer and the graphite manufacturer. 爱游戏平台注册登录 ’s unique, transversely-heated graphite tube includes an integrated platform. The exceptionally uniform temperature distribution obtained with transverse heating significantly reduces or eliminates condensation of the sample matrix components and "memory” effects, and improves the atomization efficiency for refractory elements.
The tubes are compatible with 爱游戏平台注册登录 PinAAcle 900T, PinAAcle 900Z, AAnalyst 600, AAnalyst 800, Model 4100ZL, Model 4110ZL, Model 5100ZL, SIMAA 6000 Zeeman AA instruments.

鉛和鎘等有毒元素正通過環境汙染進入食物鏈。水稻作為亞洲消費最廣泛的穀類糧食，能迅速從土壤中吸收鉛、鎘，從而通過飲食嚴重危害人類健康。這些有毒元素的含量需要仔細監測。亞洲國家，特別是我國，對鉛、鎘的限量有嚴格的規定；因此，開發一種簡便、可靠的測定大米中痕量鉛、鎘的方法至關重要。歐盟和中國要求穀物中鉛和鎘的最高允許水平低於0.2mg/kg（歐盟委員會法規EC1881/2006和中國GB 2715-2016衛生標準）。石墨爐原子吸收光譜法（GFAAS）是官方推薦的檢測各種食品中微量元素的技術（GB/T 5009.15-2017，GB/T 5009.12-2017和EN 14083:2003）。食品樣 ...
鉛和鎘是糧食中常見的汙染物，毒性極強。鉛對人體器官有害，即使是微量的鉛，一旦在體內蓄積，就會抑製血紅蛋白的形成和神經係統紊亂。鎘甚至被列為人類致癌物[根據國際癌症研究機構的數據，1類致癌物] 。據報道，鎘會導致嚴重的腎髒問題，這可能是致命的，也與脆性骨骼和肝髒問題有關。水稻作為亞洲/中國消費最廣泛的穀類糧食，能迅速從土壤中的毒素、農藥和肥料中吸收鉛和鎘，從而通過飲食危害數百萬人的健康。因此，開發一種簡便、可靠的檢測水稻中鉛、鎘含量的方法顯得尤為重要。根據中國國家標準《GB 2715-2016糧食衛生標準》，糧食中鉛或鎘的最大濃度必須低於0.2 mg/kg；歐盟的允許水平相同[EC 1881/2 ...
