Skyrocketing costs of metal coating materials such as zinc have driven the need for improved process control. Anything other than the optimum coating thickness is unacceptable either from a quality control or cost control standpoint. The time has come for a fast, nondestructive, and accurate method of measuring coating thickness and coating weight, and analyzing plating bath solution. Handheld x-ray fluorescence (XRF) offers general metal finishers and others the advantage of at line testing, eliminating the need to cut samples and spend valuable time taking the sample to a benchtop analyzer to wait for results.

The word Numismatics comes from Latin origin and means the study or collections of coins, tokens, paper money, and sometimes related objects (such as medals)1. When discussing the value of coins it is important to distinguish between the bullion value of a coin (i.e. the coin’s value based on its precious metal content) and its numismatic value. Coins with numismatic value (“numismatic coins”), are collectible coins valued for their age and rarity rather than, or in addition to their precious metal content. Numismatic coins are typically sold to and traded among collectors, who may be interested in them for their historical, cultural, or investment value. They may be purchased from wholesalers, national and local retail outlets and brokers, and certification labs.

Fire assay is an established and proven method for testing the purity of gold jewelry and other objects. Nevertheless, it is a destructive and time-consuming process requiring the use of hazardous chemicals. X-ray fluorescence has emerged as a non-destructive alternative to the fire assay method, with comparable accuracy in just minutes. XRF instrumentation is now available in portable units ideally suited for countertop use in retail environments for accurate testing of any precious metal. In a test against two different refineries using fire assay to evaluate two gold ingots from the same melt, an XRF analyzer provided results just as accurate as one refinery, and even more accurate than the second refinery. The test results provided in this article were performed using the Thermo Scientific? Niton? DXL Precious Metal Analyzer.

More than ever, highly variable compositions andvolatile prices of platinum (Pt), palladium (Pd), and rhodium (Rh) are important factors in the purchase and recycling of spent catalytic converters. In 2010, the global sales of Pt, Pd, and Rh totaled, respectively, 245, 299, and 27.2 tons. About 46% of the total Pt, 57% of the total Pd, and 77% of the total Rh were consumed by the automotive catalyst industry. That same year, 33.7 tons of Pt, 41.2 tons of Pd, and 7.3 tons of Rh were recovered from the recycling of spent catalytic converters [1], representing a total value of $3 billion at the 2010 cumulative average price of fine metals.

铀是重要的核燃料，铀资源是核能可持续发展的重要保障。20世纪90年代以来，可地浸砂岩型铀矿由于其采购成本低、对环境污染小成为我国铀矿勘查的主攻目标类型，主要包括古河道型、区域曾间氧化带型和潜水层间氧化带型3种。

在炼油行业，管道和设备内的硫化腐蚀是导致管道泄漏的一个重要原因，硫化腐蚀可导致管道和设备寿命缩短，从而必须提前更换，以及非计划中的停运，有潜在财产损失和造成人身伤害的危险事故。若暴露于无H2的硫化腐蚀环境中，低硅含量（Si<0.10％）碳钢的腐蚀速率更将加快。

Fasteners are such a universal component of so many machines and assemblies used on a daily basis that we tend to take them for granted, until something goes wrong. Fasteners, particularly those used in mission-critical situations, must be designed, fabricated, inspected, and installed properly or lives can be put at risk. For this reason, it is imperative to ensure that fasteners for these critical applications are made from the precise metal alloy called for in the design specifications. This verification can be accomplished quickly, easily, and accurately using a handheld x-ray fluorescence (XRF) analyzer.

Sulfidic corrosion of piping and equipment within the refining industry continues to be a significant cause of leaks and issues that can lead to early replacements, unplanned outages, and incidents potentially resulting in loss of property and injury to workers. Carbon steels with low-silicon (<0.10%) content can corrode at an accelerated rate when exposed to H2-free sulfidation corrosion conditions.

Lead has no known physiologically relevant role in the human body. Its presence has only been shown to be harmful. This is why, for example, many nations have switched to unleaded gasoline, thus greatly reducing the amount of lead found in the environment. And clearly, lead has no place in our drinking water.
