Product analysis Halogen analysis

We have established a system that allows us to provide results within a minimum of 3 business days from the start of the analysis!

Historically, halogen elements such as chlorine and bromine have been used as flame retardants in electronic and electrical devices and their associated products. When these materials are disposed of or incinerated, dioxins and other harmful substances may be generated depending on the combustion conditions, leading to environmental pollution. Additionally, certain manufacturing processes can negatively impact equipment, causing deterioration. Therefore, international standards such as IEC (International Electrotechnical Commission) 61249-2-21 and the US IPC (Institute for Printed Circuits) 4101B, as well as domestic organizations like the Japan Printed Circuit Association (JPCA), have defined halogen-free standards and are promoting the transition to alternatives. Halogen elements are used in various fields as flame retardants and in applications such as plastic components, cables, printed circuit boards, electronic components, connectors, films, adhesives, and tapes. Naito Environmental Management Co., Ltd. has established a system that allows for precise analysis of chlorine, bromine, fluorine, and iodine, providing results within as little as three business days from the start of analysis to the reporting of results.
