Environmental monitoring and testing assess the quality of our air, water, soil, and overall ecosystems. Using advanced technologies and analytical methods, environmental scientists collect and analyze samples to measure levels of pollutants, contaminants, and other factors impacting environmental health. By monitoring changes over time and identifying potential risks to human health, this field plays a vital role in informing policy decisions and implementing effective mitigation strategies. Explore how environmental monitoring and testing contribute to safeguarding our planet's well-being and promoting sustainable development.
Functional groups, such as octyl (C8) and octadecyl (C18), can be bonded to the silica surface to provide non polar interactions. Each of these sorbents exhibits unique properties of retention and selectivity for a particular analyte. The choice of which sorbent is best for a particular method will be influenced by the percent recovery of analyte from the sample matrix and the cleanliness of the resulting chromatography.
This mixed phase chemistry, in which two primary modes of attraction are present, allows for a more efficient and selective extraction compared to traditional reversed phase techniques. Neutral and ionized analytes can be simultaneously extracted from a complex mixture and eluted as separate fractions. A mixed phase sorbent offers the following advantages: Eluting acidic and neutral analytes separately from basic analy…
This chemistry promotes high retention of a wide range of analytes, reducing method development time and facilitating a generic approach to sample preparation.

The Empore™ High Performance Extraction Disk Plate differs in design from plates offered by other manufacturers and requires a specific vacuum manifold. Manifolds supplied by different plate manufacturers are specific to the design of their plates and cannot generally be used with plates from other manufacturers. In some cases, the use of spacers to raise/lower the height of a collection device inside the manifold may overco…
