QuEChERS Kit

1) Basic Information

Product	QuEChERS Kit
Sorbent Phase	MgSO4 NaCl NaCitrat Na2HCitrat NaHCO3 NaAcetat MgSO4·H2O K2CO3 Na2SO4 CH3CO2K
Application	sample preparation in analytical, environmental, food, and pharmaceutical laboratories.

2） Product Overview

Choose extraction kits matched to your testing protocol (10 g / 15 g sample original protocols, EN or AOAC standard methods). Buffered salt kits are especially recommended for pH-labile sensitive analytes including acid-base sensitive pesticides.
Pre-packaged salt blends are preloaded inside sample tubes by default. The tubes feature easy opening design and allow full complete transfer of contents. Compared with bag-packed salt reagents, this format has demonstrated superior operability in years of practical lab use.

3） Key Features

Fast and efficient sample pretreatment: Simplifies traditional multi-step extraction and purification procedures, greatly shortening sample preparation time.
High analyte recovery: Optimized salt-buffering and dispersive SPE purification system ensures stable and high recovery of pesticides, veterinary drugs and trace contaminants.
Excellent impurity removal capability: Effectively eliminates pigments, lipids, proteins, organic acids and other matrix interferences from complex samples.
Wide compound compatibility: Suitable for acidic, neutral and alkaline analytes, including pH-sensitive pesticide residues and polar trace compounds.
Standard method compliant: Fully consistent with mainstream EN and AOAC official detection methods, supporting 10 g and 15 g sample pretreatment protocols.
Low solvent consumption & eco-friendly: Requires less organic solvent compared with traditional liquid-liquid extraction, meeting green laboratory requirements.
Stable and reproducible results: Precisely pre-weighed salt mixtures and sorbents reduce manual errors and ensure consistent batch-to-batch performance.

4） Applications

Food safety detection: Extraction and purification of pesticide residues, veterinary drug residues, mycotoxins, additives and illegal additives in fruits, vegetables, grains and animal-derived foods.
Agricultural sample analysis: Quantitative detection of trace organic contaminants in agricultural products and planting substrates.
Environmental monitoring: Pretreatment of soil and water samples for trace organic pollutant analysis by HPLC, GC-MS and LC-MS.
Pharmaceutical and biological analysis: Clean-up of complex biological and medicinal matrix samples for trace target compound detection.
Official third-party testing laboratories: Routine high-throughput sample pretreatment for standardized and quantitative chromatographic analysis.
