System 2 Electrodeless Discharge Lamp for the detection of elemental Lead (Pb). Note: PinAAcle™ instruments require the purchase of an EDL driver assembly, part number 03030997, for each of the lamp positions to be used.
Electrodeless Discharge Lamps for greater brightness (EDLs) are typically much brighter and, in some cases, provide better sensitivity than comparable HCLs. EDLs are preferred for certain volatile elements. They offer better precision and lower detection limits for analyses that are “noisy” due to weak hollow cathode emission.
Electrodeless Discharge Lamps (EDLs) are designed to be physically interchangeable with Intensitron Hollow Cathode Lamps. Their power supplies are built into all the PinAAcle™ series of atomic absorption spectrometers. Use of EDLs with those instruments requires only the purchase of an EDL driver assembly for each of the lamp positions to be used.

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 ...
