闪闪发光的不都是金子:如何识别假冒金条

作者  -

随着黄金价格的飙升,假冒金条已经成为贵金属行业中的一个不容忽视的问题。现代假货可能看起来、摸起来都像真货,如果不使用适当的工具进行检测,要识别假冒金条不啻于一项艰巨的挑战。我们已经开发了一种分两步完成的解决方法,可以快速方便地探测出假冒金条。

步骤1:

使用X射线荧光(XRF)分析仪检测金条的外部。 XRF分析仪可以确定金条的纯度,方法是直接测量金元素和痕量元素的含量,痕量元素包含银、铜、镍、铂、钯、铱以及其它一些通常与金元素形成合金的元素。我们的XRF分析仪配备了使用方便的软件,可以显示金元素的百分比、克拉等级,或成色。如果可能存在镀金情况,镀金报警功能就会通知用户。

步骤2:

使用我们的超声检测(UT)仪器检测金条的整个体积,以确保整个金条都是“真金”。高水平假冒金条的外面可能是真正的黄金,而在内里可能会填充某种较为便宜的金属。穿过任何一种媒介的超声波都会持续在同一方向上传播,直到碰到另一种不同材料的界面。来自金条内部而不是金条底面的反射,会改变声波传播的模式,从而可表明金条内部掺入了另一种金属,或金条内有空隙。

对黄金进行超声检测

我们的XRF和UT技术可以帮助用户减少无意中买进或卖出假冒金条的风险。要了解更多信息,请参阅以下参考资料:
