Emergency meeting! This time we will focus on the pretreatment of PFAS in environmental samples, as inquiries have surged!

The measurement of PFAS (perfluoroalkyl substances) is becoming increasingly important in the field of environmental testing. In particular, accurate and efficient quantitative analysis is required in complex matrices such as non-potable water, soil, and biosolids, including wastewater and rivers. In light of this, there has been a surge in inquiries regarding PFAS pretreatment in accordance with EPA Method 1633 since the end of last year. Therefore, we will urgently hold a seminar in February to address these challenges, changing our original schedule. 【Event Overview】 ■ Date: February 27, 2025 (Thursday) ■ Time: 13:30 - 14:15 JST (45 minutes) ■ Participation Fee: Free <Pre-registration required> https://register.gotowebinar.com/register/8028605763632700251

We will introduce the selection of SPME Arrows and the appropriate conditioning procedures!

This document serves as the instruction manual for the "Restek PAL SPME Arrow." It provides detailed information on the appropriate selection of SPME Arrows based on the characteristics of the analyte, as well as heating conditioning and solvent washing. The content is presented alongside diagrams, making it easy to reference. We encourage you to read it and make use of it. [Contents] ■ Selection of SPME Arrows ■ Heating conditioning and solvent washing of SPME Arrows *For more details, please refer to the PDF document or feel free to contact us.

We propose the most suitable WAX type GC column for your application.

WAX-type fused silica GC columns use highly polar polyethylene glycol (PEG) as the stationary phase, enabling excellent separation of polar compounds that are difficult to achieve with non-polar or low-polarity columns. WAX columns exhibit varying heat resistance, inertness, and selectivity due to the optimization of stationary phase chemistry, allowing them to perform well for specific analytes.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who wish to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. You can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520" depending on the application and installation location. 【Recommended for such places!】 ☑ Entrance facing a busy corridor ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passages ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing, contributing to energy-saving by minimizing wasteful power consumption ● Equipped with a light touch function, allowing the door to open and close just by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.

Japan is among the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of significant earthquakes occurring. For the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake measures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" ◎ For more details, please download the materials or contact us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
