"Reliable Analysis of Glycol in Water by Split Injection" #Technical Document #Application Note

Reliable analysis of glycol in water by split injection.

In the analysis of low-concentration glycols in water samples using splitless injection, it is difficult to obtain stable results. This is mainly due to issues such as backflushing, abnormal peak shapes, and shifts in retention time. The split injection method presented here can avoid these problems and ensure good chromatography results. Durability tests confirmed that the Rtx-Wax column produces stable results even after 600 water injections.

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.

• Other physicochemical equipment

The glass pot lid has a hydrophilic heat-resistant coating, allowing you to check the cooking state without any fogging.

"Because it's an invisible place, we won't overlook it." Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence.

Explosion-proof motors available in stock We will deliver within 7 days to meet your delivery schedule. 【What is an explosion-proof motor?】 In factories and plants, flammable gases and vapors are present. When these mix with air and come into contact with an ignition source, an explosion or fire can occur. This motor is designed with measures to eliminate such ignition sources. 【Available stock models】 ■ Pressure-resistant explosion-proof motors, explosion-proof grade d2G4 - Foot-mounted type, output 0.4 to 3.7 kW, 4 poles - Flange type, output 0.4 to 0.75 kW, 4 poles ■ Increased safety explosion-proof motors, explosion-proof grade eG3 - Foot-mounted type, output 0.2 to 0.75 kW, 2 and 4 poles - Flange type, output 0.2 to 0.75 kW, 2 and 4 poles

As part of the "Hometown Ibara Future Creation Human Resource Development Project," we welcomed local elementary and middle school students to the special summer program "Ibara Job Exploration Tour 2025," a collaboration between the Ibara City Chamber of Commerce and the Corporate Branding Committee. We conducted a presentation that clearly and enjoyably introduced how our technology supports society, allowing the children to learn about the appeal of manufacturing and the significance of working while interacting with actual devices and products. Through this initiative, we hope to deepen our connection with the community and nurture the curiosity of the children who will carry the future. We sincerely thank everyone who participated, as well as all those involved in planning and organizing the event.

We will disclose the interim financial results for the fiscal period ending December 2025.
