To ensure the safety of human drinking water and prevent germs from being introduced into the water supply system, disinfection must be applied to the reuse water in purifying sewage and preparing drinking water. However, while the chlorination of drinking water has been a boon to human health, it has also brought new hazards. The disinfectants used in the disinfection process often react with some natural organic matter (NOM) contained in the water to produce a variety of disinfection by-products (DBPs) that are toxic to humans.
Therefore, Lifeasible has established a solution for disinfection indicators in water, covering a variety of pre-treatment methods and multiple detection methods, allowing simultaneous determination of many samples with high detection sensitivity, low interference, qualitative and quantitative accuracy to meet customer requirements for water sample testing.
Some DBPs are present in water at very low concentrations (e.g., halo acetic acids, HAAS), generally at the μg/L level, so Lifeasible requires pre-treatment such as enrichment prior to detection. We use liquid chromatography, capillary electrophoresis (CE), high-field asymmetric waveform ion mobility spectrometry (FAIMS), molecularly imprinted electrochemical sensor (MIECS), and solid-phase extraction (SPE), solid-phase extraction (SPE), solid-phase microextraction (SPME), liquid-liquid extraction (LLE), liquid-liquid microextraction (LLME), etc. to achieve DBPs separation and enrichment to meet the determination purpose of trace analysis in water.
To avoid bias caused by a single method, Lifeasible usually combines one or more methods for separation, enrichment, and detection to ensure that we provide our customers with highly sensitive and reproducible results.
