The importance of direct reading optical emission spectrometer in modern industry

Detection of the elemental content of alloys is vital in modern industry to ensure the quality and performance of materials. Usually, this involves the use of an elemental analyzer, such as a direct reading spectrometer, to accurately measure the content of different elements in an alloy. Utilizing direct reading spectroscopic techniques, these instruments are able to excite solid alloys and then acquire spectra to ultimately determine the content of each element in them, which is fast and accurate. The elemental composition of an alloy has a significant impact on its properties and uses.

Stainless steel is an important alloy usually made from a mixture of iron, chromium, nickel and other metallic elements. Its resistance to rust and corrosion derives mainly from the chromium content of the alloy, which forms a strong, self-repairing film of chromium oxide on the surface of the alloy, which is not observable to the naked eye. The commonly mentioned ratio of stainless steel to nickel is generally 18:10, but different types of stainless steel may have different alloy compositions to meet the needs of different applications.

Stainless steel is beginning to be used in a wide range of product design applications. Designers took full advantage of its toughness and corrosion-resistant properties to develop many new products that touched many previously uncharted territory. This series of design attempts was very revolutionary, such as the emergence of sterilizable and reusable stainless steel equipment in the medical industry.

Stainless steel can be categorized into four main types: austenitic, ferritic, ferritic-austenitic (composite), and martensitic. In household products, austenitic stainless steel is usually used because of its excellent corrosion resistance and good mechanical properties.

Chromium is usually present in stainless steel as an alloying element and is used to enhance the hardness of stainless steel. In addition, chromium is also widely used in decorative plating. Decorative chromium plating is usually plated as a surface layer on top of the nickel layer, which has a delicate, mirror-like polished effect and makes stainless steel products more attractive.

However, the application of chrome plating requires careful consideration of its thickness. Typically, decorative chrome plating is only 0.006 mm thick. When considering the use of chromium plating, due consideration must be given to its potential hazards. In recent years, more and more industries have tended to replace hexavalent decorative chromium water for safety and environmental reasons, as hexavalent chromium is considered to be highly carcinogenic, whereas trivalent chromium is considered to be relatively less toxic and more environmentally friendly.

In general, testing the elemental content of alloys and understanding the properties of alloys are critical to ensuring the quality of alloy products. Attention needs to be paid not only to the basic composition of the alloy, but also to possible decorative elements in the alloy to ensure that the safety and quality of the product meets the relevant standards. This information is vital for materials engineers, designers and manufacturers to ensure that their products will perform well in all areas.
