Polycyclic aromatic hydrocarbons in sludge samples
2 Dec 2019In this application note, BUCHI provides a complete pre-treatment solution for the determination of polycyclic aromatic hydrocarbons (PAHs) in environmental samples (e.g. sludge and soil, etc.) prior to quantitative analysis, including freeze-drying the sample, extraction of analyte compounds, clean-up, and concentration of the extracts.

Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Evaporators and Freeze DryersCentrifugal evaporation is used for solvent removal from a sample. This is a useful technique for sample concentration or sample drying. Many centrifugal evaporators are modular with a central vacuum pump for generating low pressure. Useful features of evaporators or vacuum ovens include minimal solvent bumping, solvent resistance, computer control, temperature regulation and benchtop design.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis. Find the best GC-MS instruments and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Contamination PreventionContamination prevention aims to control and minimize the risk of contamination during experiments. Biological safety cabinets and sterilization equipment are examples of technologies used to prevent contamination.Environmental ContaminationContaminants in the environment are harmful chemicals that are present in the air, land and water. These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.HydrocarbonOrganic CompoundsOrganic compounds are carbon-based molecules that form the building blocks of life. These include hydrocarbons, lipids, proteins, and nucleic acids. Understanding organic compounds is crucial in chemistry, biochemistry, and pharmacology.
