ソリューション
Extraction
Extraction is usually part of the analytical procedure used for determination of organic pollutants. The efficiency of the extraction influences the accuracy of results and sample through-put which is often the bottleneck of the entire procedure.
Evaporation
Environmental samples are typically extracted with an organic solvent and then concentrated to a residual volume before final analysis. Our time-saving, flexible, and highly efficient solutions guarantee reproducibility and maximum recovery rates.
Freeze drying
Analysis of environmental samples often require a sample pre-treatment to reduce the moisture content. Lyophilization, freezing a sample prior to applying a strong vacuum, is a key method to extract water from sensitive substances.
Nitrogen determination
Monitoring of nitrogen is important to ensure the quality of fresh and wastewater, agricultural soils, and air. Either the total nitrogen content or the different nitrogen containing compounds such as urea, nitrite and nitrate are of interest.
Acid digestion & Incineration
Due to their toxicity and persistence contamination of aquatic or terrestrial ecosystems with heavy metals concerns public health. Acid digestion and incineration are sample preparation steps prior to heavy metal analysis.
