Advances in PFAS Analysis: A Look into Shoko Science's Contributions

At a recent academic conference focused on groundwater and soil contamination, Shoko Science Co., a subsidiary of Shoko Bussan Co., presented significant findings related to the analysis of per- and polyfluoroalkyl substances (PFAS) in environmental water, utilizing their nitrogen spray concentration stopping device known as "EVAN-HEX." This conference, held on June 25-26, 2025, showcased collaborative research with Kurita Water Industries Ltd and Land Solution Co., aimed at enhancing the efficiency of PFAS analysis, a pressing concern in water safety today.

The Crucial Role of PFAS Analysis

PFAS are synthetic compounds often linked to various environmental and health issues. On June 30, 2025, the Japanese Ministry of the Environment implemented new water quality standards for particularly concerning PFAS, including perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA). This move reflects rising alarm over PFAS contamination spreading across Japan, necessitating effective techniques for monitoring and mitigation.

Research Outcome Presentation

During the conference, Kurita Water and Land Solution detailed the efficiency improvements achieved in PFAS pre-treatment operations under environmental assessment methodologies mandated by the Ministry. Their presentation emphasized the use of the EVAN-HEX device, which significantly optimizes the laborious pre-concentration processes traditionally required in PFAS analysis.

Conventional methods often depend heavily on skilled labor and considerable time investment to concentrate extraction solutions, leading to inefficiencies in the analysis workflow. By implementing the EVAN-HEX device, researchers maintained high precision while minimizing human error, ultimately leading to faster and more reliable results.

Technical Features of EVAN-HEX

The innovative EVAN-HEX device utilizes a combination of nitrogen spray and liquid level sensors to monitor and halt the nitrogen spray automatically once the desired liquid volume is achieved. This feature not only alleviates burdens on laboratory personnel but also enhances control over the concentration process, ensuring consistent and accurate liquid volumes post-concentration.

This technological advancement is not only pivotal for PFAS analysis; it represents a step toward a sustainable society by enabling faster detection of water contaminants critical to public health.

Insights from Kurita Water Industries

Kanji Enomoto of Kurita Water commented on their commitment to tackling PFAS contamination through robust research and development. They have established a dedicated PFAS analysis framework to streamline the pre-treatment processes within their laboratories. By automating the concentration steps through the EVAN-HEX device, they expect to enhance productivity significantly while ensuring analytical quality and consistency.

Product Overview

The EVAN-HEX device was developed and manufactured by Techno Sigma Co. and Sōzō Chemical Research Institute, with Shoko Science holding exclusive distribution rights in Japan. It stands out as an advanced tool that automates intricate concentration tasks, thereby optimizing laboratory workflows and accuracy in environmental analyses.

Future Perspectives

Shoko Science looks forward to expanding the application of EVAN-HEX across various sectors, including academics, governmental organizations, and analytical service providers. Additionally, they emphasize the importance of not just delivering equipment but also fostering a trusted support system tailored to customer needs. The EVAN-HEX will be showcased at the upcoming JASIS 2025 scientific instrument exhibition in Makuhari Messe from September 3-5, 2025, allowing attendees to explore its capabilities firsthand.
