General description

SupraSolv® hypergrade is a premium-purity solvent grade specifically engineered for organic trace analysis in gas chromatography (GC), where ultra-low background interference and maximum signal-to-noise ratio are paramount analytical requirements.

Application

SupraSolv® hypergrade solvents are indispensable in highly sensitive GC-based applications including pesticide residue analysis, dioxin and polychlorinated biphenyl (PCB) determination, mineral oil index measurements, environmental monitoring, and food safety testing — analytical domains where solvent purity directly governs method reliability and regulatory compliance.

Features and Benefits

  • Universal detector compatibility, eliminating the need for detector-specific solvent selection and simplifying laboratory workflows
  • Extended and broader specified retention time range, enabling reliable detection of both low- and high-boiling analytes within a single analytical run
  • Batch-to-batch consistency and rigorous lot-specific quality control, ensuring reproducibility across analytical series
  • Minimized matrix-induced interferences, critical for achieving accurate quantification at ppt to ppb concentration levels

Analysis Note

The hypergrade designation reflects adherence to exceptionally stringent analytical thresholds, including:• ≤ 1 ng/mL interfering impurities relative to tetrachloromethane by GC-ECD• ≤ 2 pg/mL for lindane equivalents by GC-ECD• ≤ 2 ng/mL for n-tetradecane equivalents by GC-FID and GC-MSThese specifications ensure that solvent-derived background signals remain below the detection threshold of the most sensitive analytical methods, thereby safeguarding the integrity of trace-level quantification.
