Water Emerging Contaminants Analysis

In recent years, some emerging contaminants at trace concentrations, also known as micropollutants, have been frequently detected in urban sewage, surface water, and drinking water. They seriously threaten the ecological security and the safety of drinking water. Considering the impact of these contaminants on aquatic organisms and human health, data analysis on these contaminants is required. Therefore, the development of sensitive and reliable analytical techniques is essential to monitor the occurrence of emerging contaminants in water.

For many years, BOC Sciences has been working closely with environmental monitoring and environmental regulation agencies to develop some practical detection technologies for emerging contaminants. We can analyze both target compounds and non-target compounds in order to provide technical support for the upgrading of related water environments.

Test Items

By continuing to pay attention to the relevant standards for new pollutants in various countries, we have actively carried out relevant testing services, including but not limited to the following items:

Detection Technologies

At BOC Sciences, we have moved away from age-old extraction techniques such as mechanical shaking or Soxhlet extraction in favor of the emerging Ultrasound-Assisted Extraction (UAE), Microwave-Assisted Extraction (MAE) and Pressurized Liquid Extraction (PLE) as preferred options. In addition, regarding extraction techniques, we mainly choose extraction techniques that require less solvents, such as matrix solid phase dispersion (MSPD), pressurized hot water extraction (PHWE) and microextraction with packing material (MEPS).

In terms of instrumentation techniques, we used gas chromatography (GC) and liquid chromatography (LC) combined with time-of-flight mass spectrometry (TOF-MS). The resulting data were processed with a deconvolution procedure to locate chromatographic peaks and extract their mass spectra. The advantage of this approach is that a large analyte population can be screened without information on sample composition, obtaining the most comprehensive knowledge.

Service Advantages

By choosing our analysis service, you can:

• Exceptionally low limits of detection (LOD) and limits of quantitation (LOQ) for a wide range of contaminants
• Significantly reduced analysis time
• Meet stringent regulatory and directive requirements
• Provide remote guidance and training services to enable you to obtain additional "reliable assurance of analytical data"

With a customer satisfaction rate of 98%, BOC Sciences' service engineers are the most respected and best-trained technical support team in the industry. We can help you solve problems quickly, enabling you to obtain confirmation and quantification of emerging contaminants in the shortest time possible, and optimize your reporting resources.
