贵金属测试
黄金，铂金和银珠宝的无损分析
X射线荧光（XRF）提供了用于测试珠宝，文化遗产和由金，铂或银制成的其他有价值物品的非破坏性手段。便携式XRF（PXRF），有时称为XRF“枪”或手持式XRF，提供任何位置的组成和纯度分析。Desktop Micro-XRF可以详细提供层分析。通过专家，回收商，炼油厂和散装珠宝专业人员探索Bruker对XRF分析贵金属的选择。
金karat测定
Rapid Precious Metal Analysis by Portable XRF
这S1 TITAN和CTX.are portable jewelry testers that provide accurate and repeatable karat hallmarking for gold jewelry. The karat is a measure of the purity of gold, with 24 karats being pure gold. Spelled carat in UK English, this fractional measure of gold is extremely important and has been adopted as an official measure in US law. For example, 18 karat gold is 18 parts gold and 6 parts another metal (18+6 = 24). Bruker's elemental analyzers convert the elemental percentages of gold into a karat measurement.
Bruker Gold珠宝测试仪提供金浓度数据和全种样品的2-5秒的金色浓度数据和全合金化学，并实现测试而没有任何损坏或改变样品。完全非破坏性分析以百分比的百分之十分之一的火灾测定，使黄金珠宝在黄金和行业的许多企业中易于测试。便携式XRF用于黄金分析的一些优点是：
快速测量时间从2到15秒的范围
On-screen results with output available in percent (%), karat (Kt) or PPM
Complete alloy composition from simultaneous multi-element analysis
轻量级且易于使用的仪器，不需要高技能的操作员
完全可下载的结果，记录保存，报告生成和趋势分析
珠宝层和涂层
珠宝涂料和微XRF的层分析
涂料最常用于珠宝，通过涂覆铜或银色首饰，通过纯金层涂上铜或银色珠宝来改善美学。M1 Mistral.，微点XRF是一种快速且完全无损的装饰贵金属珠宝涂料的质量控制方法。M1 Mistral.可以准确地分析金，铑或钯涂层，以确保正确的厚度和涂料组合物。除涂层厚度分析外，M1 Mistral.还可以快速测试珠宝和其他贵金属物品的组成和金karat值。
Gold Coating is used to deposit a thin layer of pure gold onto the surface of another metal, which is most often copper or silver, by either chemical or electro-chemical plating. It is generally used on low-cost jewelry because it is inexpensive and easy to apply. Thin gold plating lacks durability and can discolor if the jewelry is subject to only normal wear. Most gold plated jewelry is only one micron thick and can be easily analyzed with theM1 Mistral.。
物理气相沉积（PVD）用于在真空室中蒸发金并将其存放在珠宝上。当PVD与氮化钛使用非常硬的材料时，它提供了一种非常耐用的金涂层，这通常使用更高价格的珠宝 - 特别是手表。
Rhodium is another commonly used jewelry coating, it is silvery-white and very hard precious metal that is used to guard the surface against scratches. It also gives a nice reflective white appearance. It is most commonly used on white gold jewelry but it is used also for silver and other materials.
银分析
使用便携式XRF进行银色分析
这S1 TITAN和CTX.provide 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纯度of the silver they purchase to make jewelry as well as monitor their own process in alloying pure silver.
在购买硬币，珠宝或“纯银”之前，珠宝经销商可以在现场确定银色纯洁
回收商可以识别电气元件，电池和催化剂中的银含量
博物馆可以根据本文的银色内容（以及其他元素）进行身份验证和占用照片
文物中的银色含量可以帮助确定出处
Platinum Group Elements
铂金组元素与XRF估值
在购买，销售或回收铂族金属（PGMS） - 普拉蒂铂（Pt），钯（Pd）和铑时，重要的是能够快速，有效地可靠地确定纯度。布鲁克S1 TITANorCTX.可以提供当今最大的市场所需的信心和速度。仅仅在几秒钟，铂金和其他贵金属的纯度和值可以确定：
实验室质量由紧凑，电池供电的仪器产生
No hazardous waste, chemicals, or consumables
精确测量金属含量，例如在93％和95％铂金之间
Excellent correlation to lab results, without the high cost of sending samples to an outside lab
除PGMS-铈（CE），镧（LA），铁（Fe），镍（Ni）和铜（Cu），锌（Zn），锆（Zr），钡（Ba），锇（OS）和铅（PB）
