In the parameter table provided by handheld spectrometer manufacturers, there is a parameter called filter, which often includes the names of some elements, such as aluminum (Al), tungsten (W), etc. During the process of testing materials such as aluminum alloy and soil, one often hears a sizzling ~ sizzling ~ sound. This is actually the sound of the motor inside the handheld spectrometer rotating, switching between different filters. So, what impact do filters have on the materials and elements

The term heavy metal pollution is no stranger to everyone. Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds. There have been many accidents due to excessive heavy metals in recent years. For example, Minamata disease in Japan was caused by mercury pollution. The degree of harm depends on the concentration and chemical form of heavy metals present in the environment, food and organisms. Heavy metal pollution is mainly manifested in water pollution,

The differences in the contents of platinum, palladium and rhodium and the corresponding price fluctuations are becoming important influencing factors for the purchase and recycling of three-way catalytic converters. The materials of the three-way catalytic converter can be either a ceramic base (bluestone coated with precious metal seal paint) or a metal base (coated with alumina seal paint containing precious metals). Nowadays, there is no technology that can analyze uneven materials like cata

SDD or PIN: Which detector does your handheld XRF analyzer need?When purchasing a handheld XRF analyzer, determining whether you need a silicon drift detector (SDD) or a PIN detector is one of the primary choices you need to make.Two instruments in the KMX-RAY XRF series are equipped with two different detectors: the k-1688 analyzer is equipped with a Si-PIN detector (from MOXTEK, USA), while the K-8000PLUS analyzer is equipped with an SDD detector (from KETEK, Germany).SDD vs. PIN: What are the

I. Matters needing attention during the use, transportation and storage of handheld spectrometers such as KMX-RAY K Series handheld alloy analyzers, ore analyzers, ROHS detectors, and handheld soil heavy metal detectors:1.Handheld spectrometers should be handled with care to avoid external impacts and drops2. Pay attention to protecting the film of the detection window to prevent it from being punctured and damaged3.After the work is completed and the handheld spectrometer is turned off, if it i

Science and technology are in a stage of continuous progress and development. Archaeology is no longer confined to the traditional level of archaeology, and science and technology are increasingly applied to the study of cultural relics. Inorganic material testing technology is one of the main methods used in the research of ancient ceramics in recent years. It can make up for the deficiencies of traditional archaeology in studying the composition and structure of substances, porcelain-making te

X-ray tube(1) Cathode - emits electrons. It is generally made of tungsten wire and releases thermal radiation electrons when heated by electricity.(2) Anode - target, causing electrons to suddenly slow down and emit X-rays.(3) Window - X-ray exit channel. It can both allow X-rays to be emitted and seal the tube. The window material is Lindeman glass composed of metallic beryllium or lithium beryllium borate. The window is often inclined at an Angle of 3 to 6 degrees to the target surface to redu

X-ray fluorescence analysis (XRF)Generally, X-ray fluorescence analysis is classified into energy dispersive X-ray fluorescence analysis (EDXRF) and wavelength dispersive X-ray fluorescence analysis (WDXRF) based on the differences in the spectrometric systems. Although EDXRF and WDXRF both belong to X-ray fluorescence analysis, there are significant differences in their principles and instrument structures, as well as obvious variations in their functions and performances. A thorough understand

With the introduction of the Ten Measures for Soil, the soil remediation industry in China has developed rapidly. The demand for soil testing runs through the entire process of soil pollution remediation work, from the initial investigation of soil contaminated sites to the later assessment of soil remediation effects, all of which involve soil testing. Soil testing is the foundation for doing a good job in soil remediation. The handheld soil heavy metal detector can conduct on-site detection an
