General description
SupraSolv® MS is a dedicated high-purity solvent grade specifically engineered for sample preparation and extraction in gas chromatography coupled with mass spectrometric detection (GC-MS)
Application
SupraSolv® MS solvents are routinely employed in highly demanding GC-MS-based analytical workflows, including polychlorinated biphenyl (PCB) determination in water and soil, pesticide residue analysis in food commodities such as fruits and vegetables, environmental contaminant profiling, dioxin screening, and multi-residue methods — applications in which unambiguous mass spectral identification and accurate trace-level quantification are of paramount regulatory and scientific importance.
Analysis Note
SupraSolv® MS solvents are produced via purification processes, yielding:
- Extremely low levels of non-volatile residues and evaporation residues, preventing column contamination and ion source fouling
- Minimal intrinsic volatile organic impurities, verified by GC-MS testing across the full chromatographic retention time window
