Environmental Water and Soil

BTEX analysis made faster and easier through SIFT-MS.  Detect BTEX contamination in water and soil direct from headspace or after extraction.  Perform high-throughput automated VOC analysis of >12 samples per hour, avoiding the time consuming drying steps associated with GC and GC/MS.

 

This application note demonstrates the linearity and repeatability achievable with automated SIFT-MS analysis of chlorinated volatile organic compounds (VOCs) in water. The sample throughput achievable with SIFT-MS is at least three-fold higher than traditional purge-and-trap gas chromatography methods.

In this webinar, we discuss how analytical method validation is approached for SIFT-MS so that data collected can be used to support regulatory requirements. This is achieved by applying a strategic approach in accordance with ICH Q2(R1) guidelines. Finally, we will illustrate SIFT-MS method validation using two case studies: 1) common toxic volatiles in water, 2) BTEX in soil following methanolic extraction.

Learn about direct mass spectrometry by SIFT-MS which provides real-time, quantitative analysis of volatile compounds with trace-level sensitivity.  There are also no requirements of chromatography, pre-concentration, or sample prep!  SIFT-MS is easy to use and interpret data. 

In this webinar, we demonstrate the advantages of using automated SIFT-MS to analyze volatiles in diverse matrices: from air samples to the headspace of polymers, soil and water samples. Formaldehyde and the BTEX compounds (benzene, toluene, ethylbenzene and the xylenes) will be utilized in various case studies. In addition, high-throughput thermal desorption-SIFT-MS and real-time thermal extraction-SIFT-MS are presented for the first time.

This application note demonstrates the linearity and repeatability achievable for low molecular weight alcohols using automated selected ion flow tube mass spectrometry (SIFT-MS).

Using the environmentally significant BTEX compounds (benzene, toluene, ethylbenzene and the xylenes) as a case study, we demonstrate high-throughput analysis from several matrices (air, water and soil). For the BTEX compounds, detection limits in the single-digit part-per-billion concentration range (by volume). We also present a calibration approach that enables speciation of ethylbenzene from the xylenes in real-time.

Selected ion flow tube mass spectrometry (SIFT-MS) combined with GERSTEL automation greatly simplifies analysis of benzene, toluene, ethylbenzene and the xylenes (BTEX) in water. This application note demonstrates the linearity, repeatability and sensitivity achievable with automated SIFT-MS. Automated static headspace (SH)-SIFT-MS provides sample throughputs at least three-fold higher than traditional purge-and-trap-gas chromatography methods.

Combining direct analysis using selected ion flow tube mass spectrometry (SIFT-MS) and automated sample preparation, determination of benzene, toluene, ethylbenzene, and the xylenes (BTEX) in soil via methanolic extraction is simplified and accelerated. This application note provides an initial validation of the automated SIFT-MS method and demonstrates that the sample throughput achievable with SIFT-MS is at least two-fold higher than gas chromatography (GC).

This webinar focuses on the benefits realized by adopting SIFT-MS in environmental testing laboratories, which include reduced sample preparation and increased sample throughput.

Five case studies are presented:

• Soil analysis
• Water headspace analysis
• Formaldehyde analysis using sample bags
• Canister analysis
• Landfill and biogas analysis

Become acquainted with TD-SIFT-MS through the analysis of environmental BTEX (benzene, toluene, ethylbenzene and xylene) from multiple sorbent tubes. This demonstration will address the following; - What makes this approach unique? - What does “real-time” thermal desorption data look like? - How is the automation and processing software operated? - How fast is it?

Mark describes how the ICH Q 2 (R1) guidelines can be readily applied to SIFT-MS methods, whether in scenarios where only the analytical technique is changed or for tasks that pose a unique analytical challenge. He presents case studies for two such scenarios: 1) methanolic extraction of BTEX compounds (benzene, toluene, ethylbenzene plus xylenes) from soil, 2) direct analysis of formaldehyde leaching into single-use pharmaceutical devices from polymeric components.

Direct mass spectrometry (DMS) techniques struggle to speciate ethylbenzene from the xylene isomers, yet increasingly regulators are imposing different emission and exposure limits for these compounds. This application note describes a significant breakthrough for DMS, because selected ion flow tube mass spectrometry (SIFT-MS) readily achieves direct, real-time speciation of the xylenes from ethylbenzene.

Combining the power of direct analysis using selected ion flow tube mass spectrometry (SIFTMS) and GERSTEL automation, headspace analysis of chlorinated volatile organic compounds (VOCs) in water is greatly simplified. This application note demonstrates the linearity and and repeatability achievable with automated SIFT-MS. The sample throughput achievable with SIFTMS is at least three-fold higher than traditional purge-and-trap gas chromatography methods.

This app note introduces the next generation of SIFT-MS, Syft Tracer^TM, which launched at Pittcon 2023.  It revolutionizes volatile impurities analysis workflows through unparalleled speed, performance stability, and reproducibility.  Learn about how this innovation to real-time trace gas detection outpaces chromatography-based methods in the analysis of challenging analytes such as formaldehyde in a PEG excipient.

SIFT‐MS is now recognized as the most versatile analytical technique for the identification and quantification of trace gases down to the parts‐per‐trillion by volume, pptv, range. This statement is supported by the wide reach of its applications, from real‐time analysis, obviating sample collection of very humid exhaled breath, to its adoption in industrial scenarios for air quality monitoring. This review touches on the recent extensions to the underpinning ion chemistry kinetics library and the alternative challenge of using nitrogen carrier gas instead of helium.

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 investigates concentration dependence of MHE calibration in sample matrix.  Across the full range of analytes investigated in this study, MHE calibration holds for at least one order of magnitude change in sample concentration.  For analytes in the C7–C9 range, the MHE calibration applies over two orders of magnitude analyte concentration. These results mean that the MHE workflow can be applied to a wider range of samples in the matrix, further reducing calibration demand.
