설명

General description

SupraSolv solvents for headspace gas chromatography are developed particularly for the analysis of residual
solvents in drug substances, excipients and drug products according to ICH, Ph Eur and USP - SupraSolv headspace solvents are tested for all
residual solvents defined by the ICH.

Application

DMSO can be used as an effective solvent for dissolving a wide range of polar and non-polar compounds for sample preparation in HS-GC. Its high polarity allows for the extraction of volatile organic compounds (VOCs) from complex matrices, such as biological samples or environmental matrices. DMSO also enhances the volatility of certain compounds, facilitating their detection in HS-GC. By modifying the physical properties of the analytes, DMSO helps in achieving better separation and sensitivity during the chromatographic analysis.

Saturation Concentration in Air: 8.0 g/m3 (20 °C)
