O determination in copper samples

Sample preparation Make sure that the surface of the copper is free from contaminations; otherwise clean the sample with acetone p.a. and let dry at atmosphere. In case of very low oxygen concentrations (< 5 ppm) rinse the sample in nitric acid (HNO3) first, than water, last with acetone. Let this sample dry at atmosphere and analyze immediately.

Quality Control of Coal with Elemental Analyzers

Using Combustion and Thermogravimetric Analyzers from ELTRA Coal is one of the most important fossil fuels. In 2012, the global stone coal output was about 6.6 billion metric tons [1]. A huge amount of the worldwide traded stone coal is mined in China, USA, Russia and India. Compared to the large amount of mined coal the required sample volume for the characterization of coal, varying from a few mg up to 1 gram, seems unbelievably small. The characterization of coal is important for its quality assessment and further use. Depending on the product quality, coal is suitable for coking, steel production or electrical power generation. This article takes a look at the chemical background of proximate and ultimate coal analysis and how these parameters are measured with ELTRA’s combustion and thermogravimetric analyzers.

Effective Quality Control of Steel and Iron Products with Combustion Analysis

The element concentration of carbon (C), sulfur (S), hydrogen (H), nitrogen (N),and oxygen (O) in iron products, such as steel, have a significant influence on material properties like ductility, brittleness, or hardness. Hence, reliable determination of the C, H, N, S, O contents is a routine quality control task in steel and iron production. This article explores the application fields and advantages of elemental analyzers, which are also known as combustion analyzers, in the steel industry.

德国Eltra（埃尔特）产品综合目录

德国ELTRA（埃尔特）是全球知名的元素分析仪生产厂家，隶属于弗尔德科学仪器事业部（Verder Scientific Division），可提供对固相样品快速、准确、简便的碳（C）氢（H）氧（O）氮（N)硫（S）元素分析，相比较于ICP和XRF，样品制备容易，分析范围可从几个ppm到100%。

氧（O）、氮（N）、氢（H）的含量直接影响金属（如钢铁、钛、铜）的特性，所以在质量控制过程中要精确测定其含量。ELTRA元素分析仪能精确测定氧、氮、氢和氧氮、氧氢或氧氮氢的含量。 其采用惰性气体熔融技术，将样品在脉冲炉中加热超过3000℃，熔解在石墨坩埚中，用红外吸收法测定氧含量，热导法测定氮和氢含量。典型样品如铜、钢、铸铁、合金及陶瓷和其它无机材料。H-500是专业用于检测氢元素及其同位素的分析仪器。

检测固体样品内碳和硫分是实验室和生产常见的应用。根据样品材质的不同，应选用不同的分析仪。有机样品通常具有较高的碳含量（60-100%）和可燃性（比如：煤、碳、木头），在温度达到1300℃（或更低）的时候，样品中的碳和硫元素就会完全被释放出来，推荐使用电阻炉碳硫分析仪检测。 然而，无机样品具有相对较低的碳含量（从ppm级至10%），并且一般情况下不能燃烧。样品中的碳硫元素只有在2000℃以上才可以完全释放，可选择高频感应炉碳硫分析仪。
