• Testing Equipment and Devices

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.

• Other physicochemical equipment

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 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

Testing for volatile organic compounds (VOCs) in drinking water is widely conducted to ensure its safety. Furthermore, odor substances such as methyl isoborneol (MIB) and geosmin are monitored as they cause unpleasant odors, making them subjects of analysis. This study aimed to develop a method that integrates the analysis techniques for VOCs and odor substances, which are typically conducted separately, to achieve high sample throughput. Solid-phase microextraction (SPME) Arrow is a particularly useful technique as it allows for sample pretreatment and sample introduction to be performed with a single device. Additionally, SPME Arrow can be automated using a rail-type autosampler, significantly reducing the time required for sample pretreatment. In this study, we proposed a method that efficiently measures VOCs and odor substances in drinking water by combining a simplified sample pretreatment workflow with headspace-solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS).

Using SPME Arrow and the PAL CTC autosampler for sample pretreatment, and the Rxi-624Sil MS column for analysis, we established the GC-MS optimization conditions for furan and alkyl furan in infant formula (hereafter referred to as powdered milk) and coffee samples. The results of this experiment revealed that sample pretreatment using SPME Arrow is suitable for a variety of sample types containing high and low concentrations of furan and alkyl furan. By using SPME Arrow alone for pretreatment, compared to headspace only or a combination of SPME and HS, an increase in productivity for food safety inspection laboratories is expected.
