贵金属测试

TheS1泰坦和CTX是便携式珠宝测试人员，为黄金珠宝提供准确且可重复的Karat标志。卡拉特是对黄金纯度的度量，其中24 karats是纯金。用英语拼写克拉，这种黄金的分数非常重要，并已被作为美国法律的官方措施。例如，18克拉金是18份黄金和6份另一个金属（18+6 = 24）。布鲁克的元素分析仪将黄金的元素百分比转换为卡拉测量。

Bruker gold jewelry testers provide gold concentration data and full alloy chemistry in as little as 2-5 seconds per sample, and testing is realized without any damage or alteration to the sample. Completely nondestructive analysis paired with accuracy within a few tenths of a percent of fire assay make testing gold jewelry easy for many businesses in the gold and industries. Some advantages of portable XRF for gold analysis are:

• with Rapid measurement times ranging from 2 to 15 seconds

• On-screen results with output available in percent (%), karat (Kt) or PPM

• 同时多元分析的完整合金组成

• 轻巧且易于使用的乐器不需要高技能的操作员

• Fully downloadable results for record-keeping, report-generating, and trend analysis

TheS1泰坦和CTXprovide portable and robust platforms for the analysis of silver. Pure silver (Ag), known as Fine Silver or 999.5 fineness, is much too soft to use in jewelry. However, it can be used in many other applications such as electrical components, bearings for jet engines, the formation of chemicals like formaldehyde and ethylene oxide and much more. Typically, for jewelry, silver is alloyed with another metal such as copper (Cu) to provide strength. Sterling Silver (Ag), the world standard for silver jewelry, contains 92.5% silver and usually 7.5% copper. Example applications for portable XRF include:

• 银珠宝制造商可以验证他们购买的白银制作珠宝的纯度，并在合金纯银合金中监视自己的过程。

• Jewelry dealers can determine silver purity on the spot before they purchase coins, jewelry or “pure” silver

• Recyclers can identify silver content in electrical components, batteries and catalysts

• 博物馆可以根据纸张的银含量（以及其他元素）身份验证和出处照片

• 人工制品中的银含量可以帮助确定出处
