As food scientists work to ensure food safety and quality standards, analytical laboratories face challenges in detecting and quantifying trace-level contaminants in complex food matrices. Typically, analysts use discriminative techniques, such as headspace extraction, to profile samples; however, trace-level compounds may be missed. Thus, a more selective technique is needed to capture these compounds.
SPME–trap with multi-step enrichment (MSE®) and HiSorb™ high-capacity sorptive extraction are selective methods that address this issue. These techniques are designed for detecting low-level contaminants with high precision and can be seamlessly integrated with automated platforms like Markes’ Centri® to maximize laboratory efficiency and throughput.
This eBook features in-depth content on how these advanced analytical techniques for food safety and quality are enabling analysts to discover more, with detailed application examples including:
High-Sensitivity Analysis of Residual Fumigants in Food
This application note demonstrates the use of multi-step enrichment headspace-trap (MSE-HS–trap) with GC-MS to achieve regulatory-compliant detection limits for fumigants in seeds and spices, extracting up to 5 mL sample volume with each extraction.
Detection of 1,4-Dioxane in Drinking Water
This application note explores the application of SPME Arrow-trap with multi-step enrichment (MSE) on the Centri platform, providing low detection limits for the harmful contaminant 1,4-dioxane in water samples.
Authentication of Honey Using HiSorb Sorptive Extraction
This application note showcases how HiSorb sorptive extraction probes were used to identify authenticity markers in honey, offering a rapid and reliable method for detecting food fraud with discriminatory analysis.
Also featured is the case study below:
Automated Off-Flavour Research in Aquaculture
This case study highlights the use of HiSorb extraction and Centri automation to streamline the analysis of geosmin and 2-methylisoborneol in fish tissues, enhancing productivity and reducing detection limits in off-flavour research.
