Product analysis Halogen analysis

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

Traditionally, halogen elements such as chlorine and bromine have been used as flame retardants in electronic and electrical devices and their associated products. When these are disposed of or incinerated, dioxins and other harmful substances may be generated depending on the combustion conditions, leading to environmental pollution. Additionally, it is known that the manufacturing process of these products can have adverse effects, such as equipment degradation. Therefore, international standards such as IEC (International Electrotechnical Commission) 61249-2-21 and the US IPC (Institute for Printed Circuits) 4101B, as well as the Japan Printed Circuit Association (JPCA), define halogen-free and promote the transition to alternatives. Halogen elements are used in various fields as flame retardants and in applications such as plastic parts, 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. For more details, please contact us or refer to our catalog.

Geophysical exploration technology service "Tunnel Shallow Reflection Method Exploration (SSRT)"

It is a face-forward exploration technology using the VSP processing method.

The "Shallow Seismic Reflection Survey for Tunnel (SSRT)" is a technology that uses elastic waves to predict the geology ahead of a tunnel face. It was jointly developed with Fujita Corporation for the purpose of exploring the area in front of the tunnel. Since it is possible to select artificial seismic sources (hydraulic impactors, vibrators, blasting sources) according to the conditions of the tunnel site being excavated, there are no limitations on the applicable tunnels. For example, it can also be implemented in mechanically excavated tunnels that include Tunnel Boring Machines (TBM). 【Features】 - It can be conducted outside the tunnel construction site before excavation. - Exploration is possible in hard rock formations, soft ground, tunnel entrance areas, and low cover sections. - Since exploration behind the tunnel face is also possible, it allows for a more accurate evaluation of forward exploration by comparing it with excavation results. For more details, please contact us or download the catalog.

Concrete Bridge Condition Survey Service

We will investigate the condition of the concrete bridge through physical exploration.

Our company conducts concrete bridge condition surveys using physical exploration methods. Infrared thermography allows us to investigate areas that are otherwise inaccessible. By identifying the differences in radiative temperatures between deteriorated and sound areas, we can pinpoint the deteriorated sections and use this as a basis for detailed investigations. Additionally, we measure the minute vibrations from impacts using elastic wave tomography to determine the distribution of elastic wave (P-wave) velocities within the concrete. We evaluate the condition of the measurement points based on the correlation between the condition and the elastic wave velocity. Using RC radar, we non-destructively detect deformations within the concrete that cannot be visually confirmed. Defects, voids, foreign objects, etc., appear as abnormal reflection patterns of electromagnetic waves. *For more details, please download the PDF or contact us.*
