Numerous industries make use of aluminum. These industries include construction, transportation and food as it forms alloys with a number of different 欧洲杯足球竞彩materials. Its versatility and lightweight make aluminum and its alloys particularly good for industries where weight reduction is important, such as automotive and aerospace.
然而，铸造铝远非容易。仔细控制熔体内的元素对于确保最终材料具有所需的特性至关重要。熔融控制的最有效方法是通过光学发射光谱（OES）进行分析。
However, not all OES instruments are considered equal. Particular care and attention are needed with aluminum as some of the elements must be managed within extremely low limits, meaning some analyzers may not detect the requisite values.
新的OE720 spark spectrometerfrom Hitachi High-Tech has been developed to deliver excellent performance at an accessible price point. This means that the OE720 can detect elements that typically require a specialist instrument, such as phosphorus and antimony, at low detection limits.

OE720的检测极限对于铝熔体控制很重要的元素
The new optical system of the OE720 analyzer has been innovatively designed to deliver next-level optical resolution, and the CMOS detector technology guarantees that an extensive range of elements can be determined at extremely low limits.
通过这种方式，可以在近乎共晶和高蛋白铝合金合金中检测到磷至20 ppm，以及可以控制最佳结构修饰的制造商。
This high-performance capacity enables verification that the tramp elements P, Ca, Bi and Sb within the aluminum melt do not exceed the 120 ppm maximum combined total.

OE720的技术功能可以提高性能
这OE系列具有两种型号：OE720和OE750。两种型号都在金属内的完整元素范围内提供高性能。OE720将检测熔体内的所有非气体元件，OE750包含气体检测能力，这不是铝分析的要求。
Both models gain significant advantages from these innovations:
- Ability to determine an extensive range of elements owing to a wavelength range of 174 - 670 nm (OE720) and 119 - 670 nm (OE750). With the additional capacity to expand the upper limit of the range to 766 nm for both models on request.
- 完全重新开发的光学系统和高级CMOS检测器设计在整个波长范围内提供极高的光学分辨率，从而增强了仪器的检测极限能力。
- Mid pressure system and new spark stand design to limit the amount of argon necessary and reduce power consumption by up to half. These enhancements help to significantly reduce operating costs when using the instrument 24/7.
- Sealed spark stand design and mid-pressure system provide exceptional stability and transparency and lower necessary maintenance requirements, thereby improving the uptime of the analyzer.
