VWR Acetonitrile PESTINORM® grade is a high-purity solvent developed specifically for the sensitive and accurate analysis of pesticide residues. With an assay of ≥99.7%, ultra-low evaporation residue, and minimal water content, it is ideal for GC and LC pesticide methods, including ECD and MS detection. Filtered through a 0.2 µm membrane and packaged under nitrogen to prevent contamination and oxidation, this solvent is the preferred choice for trace-level environmental and food testing.
Key Features
- High Purity (≥99.7%): Suitable for sensitive analytical techniques such as GC-ECD, GC-MS, and LC-MS
- PESTINORM® Grade: Specially formulated for pesticide residue analysis and validated for use in regulated laboratories
- Extremely Low Residue: Evaporation residue ≤5 ppm ensures minimal background interference
- Low Water Content: ≤0.05% for consistent chromatographic performance
- Filtered and Inert Packaged: Passed through a 0.2 µm filter and packaged under nitrogen for long-term stability
- Chem21 Approved: Recognized as a safer choice for human and environmental health
