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.Rigorously tested to meet stringent purity specifications that minimize endogenous chromatographic interferences across the entire relevant retention time window, the solvent quality is uniquely universal, rendering it compatible with all three principal GC detection modes — electron capture detection (ECD), flame ionization detection (FID), and mass spectrometric detection (MS) — within a single, unified product grade.

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.
