Environmental Analysis

Environmental

Protection of our environment and our natural resources is crucial. Water, our most precious food, is also our most thoroughly controlled food. Whether it is drinking water, surface or waste water, the PAL System provides the tools and workflows for automated analysis of large sample series, even the continuous online sampling from water streams.

A common technique for the control of water quality is Solid Phase Microextraction (SPME). Using the SPME Arrow lowest levels of contaminants can be analyzed. Examples include geosmin and 3-MIB, as well as poly aromatic hydrocarbons (PAHs) or pesticides.

Similar SPME applications are used for the quality control of beverages, beer brewing, or also various kind of spirits. In addition, the classical static headspace (HS) or dynamic headspace analysis are available for routine water analysis.

Environmental contaminants in water, soil or sediments like personal care products (PCPs), pesticides or hormones use either the QuEChERS extraction with micro-SPE cleanup (uSPE), or SPME Arrow techniques.

Characterization of the New PAL micro-SPE Cartridge for Pesticides Extract Clean-up

Since more than ten years micro-SPE (uSPE) emerged as a micromethod for sample preparation and clean-up in food safety, proteomics, forensic, environmental and analysis. Applications are wide-ranging and cover drugs, environmental contaminants, and, in particular, the QuEChERS extract cleanup in multiresidue pesticide analysis. The automation of the uSPE sample preparation steps led to the desired increase in sample throughput, unification of the used sorbent materials for food commodities, and the potential for the online hyphenation with GC/MS and LC/MS instrumentation.
