This study demonstrates high-throughput analysis of BTEX compounds from several matrices (air, water and soil). Detection limits in the single-digit part-per-billion concentration range (by volume) are readily achievable within seconds using SIFT-MS because sample analysis is achieved without chromatography, pre-concentration, or drying. We also present a calibration approach that enables speciation of ethylbenzene from the xylenes in real-time.

This application note summarizes key SIFT-MS results presented in a peer reviewed article entitled “Unreported VOC Emissions from Road Transport Including from Electric Vehicles.” Learn how the Wolfson Atmospheric Chemistry Laboratory at the University of York used SIFT-MS for VOC analysis in its platform to experimentally verify that motor vehicle screen wash is a significant unreported source of VOC emissions (especially for ethanol and methanol).

Method detection limits (MDLs) have been determined for the newly regulated HON (Hazardous Organic NESHAP (National Emission Standards for Hazardous Air Pollutants)) compounds, which validate selected ion flow tube mass spectrometry (SIFT-MS) as an effective solution for measuring these toxic volatile organic compounds (VOCs) and other environmental pollutants in ambient air, whether at the fenceline or in a mobile setting. SIFT-MS offers unparalleled speed, sensitivity and ease of use for environmental monitoring applications.

A comparison made between a stainless steel hardware column and an INERT column using the same lot of HALO 90 Å C18, 2.7µm results in tailing factor and area improvement using the HALO®INERT column.

The potential of smart technologies has evolved into a operational necessity - businesses were faced with the need for remote and automated operations bringing substantial improvements in productivity, efficiency, and operating costs.

More and more regulations regarding PFAS are being implemented with action limits that continue to decrease. Having a harmonized method to accurately determine the PFAS content in food, as well as other matrices, is important to ensuring long-term detection and regulation. The solvent extraction of PFAS from these varied sample matrices can be challenging given the susceptibility to contamination and the low levels in which these compounds are present. This poster, presented at RAFA 2024, examines the PFAS extraction several different food samples as well as food packing matrices.

PFAS have been shown to cause health issues in humans, which means monitoring environmental solid samples, such as soil and tissue, is critical. This application note details the extraction of 40 spiked PFAS compounds from soil and tissue following EPA Method 1633. The automated extraction was less than 10 minutes per sample and yielded acceptable recoveries and RSDs without carryover in the system. The EDGE PFAS is an ideal option for laboratories that want to automate their PFAS extractions of solid samples.

Existing solvent extraction techniques are predominantly manual methods that are not rapid, simple, or efficient. The EDGE PFAS™, an automated solvent extraction system, provides an automated, sequential approach to PFAS extraction. This system performs an efficient extraction of PFAS compounds from challenging food and food packaging matrices in one simple process. Upon completion, the final extract is filtered and ready for any minimal cleanup required, as well as analysis. Excellent recovery with tight reproducibility has been found. The EDGE PFAS method offers a rapid, simple, and efficient solvent extraction solution for PFAS testing.

There are several established PFAS standard methods that specify the use of Liquid Chromatography/Mass Spectrometry (LC/MS); however, LC/MS is unable to analyze all PFAS compounds for various reasons. With its ability to analyze these compounds in complex matrices and simplified sample prep, Head-Space Solid Phase Microextraction GC/MS is pivotal as a complementary technique to LC/MS.
