PMI Technologies: What's the Difference Between XRF, LIBS, and OES?
2024年9月3日 · The OES technique is used to grade material by measuring the element carbon, to identify alloys such as low carbon or high carbon stainless steels, low alloys such as 41xx series, 86xx series, and 10xx series carbon steels, to name a few. Although OES is considered a portable technique, it would be better classified as a transportable technique.
在PMI技术中:XRF、LIBS和OES有什么区别? - 仪器信息网
2021年7月7日 · 光学发射光谱(OES)是一种光学方法,可用于检测几乎所有类型的元素,包括不锈钢、镍和碳钢等不同基体中的碳和轻元素。 OES技术通过测量碳元素来分级材料,识别低碳或高碳不锈钢等合金,例如:41xx系列、86xx系列和10xx系列碳钢等低合金。 虽然OES被认为是一种便携的技术,但最好将其归类为可移动技术。 OES仪器的重量和尺寸因制造商而异,一般重量可达45-60磅(20-27kg)以上,并且需要一个氩气罐,根据所用罐的尺寸,该罐的重量约为20 …
哪位大神能给解释一下PMI(材料可靠性鉴别)? - 知乎
材料可靠性鉴定(PMI)是对使用的材料(尤其指金属结构领域)的安全与可靠性的现场检测。 这种现场无损检测可以验证使用的材料的化学成分合不合规。 法律规定等要求很多工厂经营者检查一切使用的材料,而不只是说凭成分证书行事。 通过材料可靠性鉴定(PMI),用户能够确认所用的合金是否符合相关规定,检查合金牌号是否正确。 材料可靠性鉴定(PMI)为什么如此重要? 我们所了解到常见的工业事故产生原因有机械完整性方面的故障。 比方说:炼油厂爆炸、应力腐 …

LIBS vs OES - A Comparison of PMI Technologies | Verichek
A recent whitepaper from Hitachi offers a thorough look at laser-induced breakdown spectroscopy (LIBS) and optical emission spectroscopy (OES) in relation to their use in product material identification (PMI). Industry regulations, scheduled inspections, and regular maintenance mean non-destructive testing (NDT) for PMI is integral to ...
Positive material identification - Wikipedia
Positive material identification (PMI) is the analysis of a material, this can be any material but is generally used for the analysis of metallic alloy to establish composition by reading the quantities by percentage of its constituent elements. Typical methods for PMI include X-ray fluorescence (XRF) and optical emission spectrometry (OES). [1]
LIBS vs. OES vs. XRF: PMI Testing Techniques - Sweet Fish Media
To choose the correct PMI testing technique (LIBS vs. OES vs. XRF), ask yourself these 4 questions: Can you allow for marks on the samples? Which elements or alloys are you needing to positively identify and measure? How quickly do you need to complete testing? Is safety liability and/or government oversight a grave concern?
