Single Element Lumina Hollow Cathode Lamp (HCL) for the detection of elemental Lead (Pb).

Every genuine PerkinElmer lamp is designed for use with and tested on our spectrometers to assure compatibility and the highest performance. We offer a wide range of single-element and multi-element HCLs, which are ideal for determining most elements by atomic absorption spectroscopy. To prolong the life of a Lumina Hollow Cathode Lamp (HCL), we produce lamps with larger internal volume so that a greater supply of fill gas at optimum pressure is available. The larger the lamp, the greater the inert gas volume - and the longer the lamp lifetime.

Note: Lumina Hollow Cathode Lamps may also be used with all earlier AA spectrometers that do not have automatic code reading capability by using an appropriate adapter cable.

氘灯扣背景校正石墨炉原子吸收法分析大米中的铅和镉(快速消解)

铅和镉等有毒元素正通过环境污染进入食物链。水稻作为亚洲消费最广泛的谷类粮食,能迅速从土壤中吸收铅、镉,从而通过饮食严重危害人类健康。这些有毒元素的含量需要仔细监测。亚洲国家,特别是我国,对铅、镉的限量有严格的规定;因此,开发一种简便、可靠的测定大米中痕量铅、镉的方法至关重要。欧盟和中国要求谷物中铅和镉的最高允许水平低于0.2mg/kg(欧盟委员会法规EC1881/2006和中国GB 2715-2016卫生标准)。石墨炉原子吸收光谱法(GFAAS)是官方推荐的检测各种食品中微量元素的技术(GB/T 5009.15-2017,GB/T 5009.12-2017和EN 14083:2003)。食品样 ...

快速消解-石墨炉原子吸收法分析大米中的铅和镉

铅和镉是粮食中常见的污染物,毒性极强。铅对人体器官有害,即使是微量的铅,一旦在体内蓄积,就会抑制血红蛋白的形成和神经系统紊乱。镉甚至被列为人类致癌物[根据国际癌症研究机构的数据,1类致癌物] 。据报道,镉会导致严重的肾脏问题,这可能是致命的,也与脆性骨骼和肝脏问题有关。水稻作为亚洲/中国消费最广泛的谷类粮食,能迅速从土壤中的毒素、农药和肥料中吸收铅和镉,从而通过饮食危害数百万人的健康。因此,开发一种简便、可靠的检测水稻中铅、镉含量的方法显得尤为重要。根据中国国家标准《GB 2715-2016粮食卫生标准》,粮食中铅或镉的最大浓度必须低于0.2 mg/kg;欧盟的允许水平相同[EC 1881/2 ...
