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.
