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

• Technical Seminar

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.

• Technical and Reference Books

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

We would like to introduce "Stability 2" handled by FCR and Bio Co., Ltd. This product is a jacket tube with a rack lid lock and anti-rotation function (compatible capacity 2.1ml). Additionally, for products equipped with the rack ID function, a 2D code for rack ID is provided on the bottom surface of the rack, allowing simultaneous reading of the tube ID (bottom surface 2D code) and rack ID within the rack, thereby reducing stress on samples during the reading process. 【Features】 ■ Polypropylene ■ Autoclavable ■ DMSO compatible ■ Compatible with liquid nitrogen vapor *For more details, please download the PDF or feel free to contact us.

Fukuda's new flagship model. - Masterless type (FLA-0200 series) - General type (FLA-0201 series) Two models of air leak testers. With the mastering correction function, high-precision measurements can be achieved in a short time. Please take a look at the catalog.

What is an Air Leak Tester? An "Air Leak Tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence of leaks based on pressure changes. When a master with no leaks and a workpiece with leaks are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence of leaks can be determined. Generally, differential pressure air leak testing is widely used, but Fukuda also offers products that utilize direct pressure leak testing and flow meters according to the leak rate, in addition to differential pressure leak testers. Since the air leak tester uses air as the measurement medium, it incurs no running costs and is environmentally friendly.

Fukuda Co., Ltd., which develops, manufactures, and sells leak testing equipment to inspect airtightness and sealing performance, provides a technical document that clearly explains the methods and theories of airtight testing, titled "Technical Manual." We are offering it as a PDF file. Please take this opportunity to download and view it!

● What is a flow meter? Flow meters measure flow rates using mass flow meters or laminar flow meters and perform pass/fail judgments based on flow rate criteria. They are ideal for measuring airflow and conducting performance tests. "FMZ-1063 series" This is a flow tester equipped with a mass flow meter. It offers high precision of ± 3.5 % of R.D. ± 1 digit (in the normal flow range). It features a time-saving function (scan measurement). The FMZ-1063 is a compact, all-in-one flow tester with various functions. "FU series" This is a flow measurement unit that integrates laminar and differential pressure sensors, making it smaller and lighter. When connected to a display indicator (model: MI-170), it can provide direct flow readings as well as pressure and flow judgments. "FLF-110 series" This is a laminar flow meter capable of measuring a wide range of flow rates from 2 NmL/min to 500 NL/min.
