The concentration of barium in barite is of great significance for protecting human health, complying with regulatory requirements, quality control and environmental protection. Manufacturers and production companies should strengthen the monitoring and testing of barium content in barite to ensure its compliance and safety, thereby improving product quality and market competitiveness.
The accurate determination of barium content in barite samples can be ensured using suitable analytical tools such as atomic absorption spectrometry (AAS), inductively coupled plasma spectrometry (ICP-OES), X-ray fluorescence (XRF), to meet relevant health, environmental and quality control requirements. Among them, X-ray fluorescence (XRF) is widely used because of its simple sample preparation, no need for special processing, and fast analysis speed.
In leather samples, the content of the following eight heavy metals is usually detected: lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), nickel (Ni), chromium (Cr), tin (Sn) , Molybdenum (Mo).
The above harmful elements may enter the human body or the environment through leather products, causing potential harm to health and the environment. Therefore, testing the content of these heavy metals in leather samples can ensure product safety and compliance and protect the health of consumers and the environment. The ROHS analyzer can accurately measure the heavy metal content in the sample and determine whether it meets the restriction requirements according to relevant regulations and standards.
RoHS analyzers and liquid chromatographs are both commonly used tools in RoHS 2.0 testing. They provide important analytical information in different aspects to ensure accurate detection of hazardous substances. Among them, the RoHS analyzer is a multi-functional analytical instrument that can be used to quickly detect a variety of harmful substances, such as lead, cadmium, hexavalent chromium, etc. The advantage is that it is fast and convenient, and the compliance of products can be monitored in real time during actual production. Liquid chromatography (HPLC) is an efficient analytical instrument mainly used to separate and detect organic substances. In RoHS 2.0 testing, liquid chromatography is usually used to detect brominated flame retardants such as polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE), which are one of the hazardous substances in plastic products.
