鉴别金银首饰,需经过光谱分析仪,才能确定。因仪器昂贵,不可能每个家庭都具备。鉴别金、银器的方法还有火烧、辨色、比重等方法。本文介绍的这种电子鉴别仪简单可靠,成本极低,现介绍给大家供参考。本装置是根据电池原理,按不同金属的活动顺序,则两种不同金属之间存在接触电位差。一般不活泼金属为正极,金、银在金属中为最不活泼金属。当铜和金、银器接触时,则
Identification of gold and silver jewelry, need to go through the spectrum analyzer, to determine. Because of the expensive equipment, it is impossible for every family to have it. Identification of gold, silverware methods are burning, color discrimination, weight and other methods. This article describes the electronic identification device is simple and reliable, low cost, are presented for your reference. The device is based on the principle of the battery, according to the order of the activities of different metals, the two different metals exist contact potential difference. Inactive metal is generally positive, gold, silver is the most inactive metal in the metal. When copper and gold, silverware contact, then
