Product Overview
Dimethyl sulfoxide (DMSO) in GC-Headspace Grade is a high-purity solvent specifically formulated for gas chromatography (GC) and headspace analysis applications. This grade ensures minimal interference with analytical results, offering exceptional baseline stability and low background noise. Its high polarity and miscibility with both polar and non-polar compounds make it a versatile choice for complex sample preparation. The solvent’s low volatility reduces evaporation losses during analysis, ensuring consistent and reproducible results. Additionally, its hygroscopic nature helps maintain sample integrity in moisture-sensitive applications. This grade is rigorously tested for impurities, including residual solvents, metals, and non-volatile residues, to meet stringent laboratory standards. Its compatibility with most GC columns and detectors further enhances its utility in high-performance analytical workflows. The solvent’s stability under thermal stress ensures reliable performance even in demanding analytical conditions.
FAQs
1. What is the shelf life of GC-Headspace Grade DMSO?
When stored unopened in its original container at room temperature, this grade of DMSO typically retains its specified purity for 24 months from the date of manufacture. Always check the label for the exact expiration date.
2. Is this DMSO grade compatible with all GC column types?
GC-Headspace Grade DMSO is compatible with most standard GC columns, including polar and non-polar stationary phases. However, we recommend verifying compatibility with your specific column type for optimal performance.
3. Can this solvent be used for LC-MS applications?
While this grade is optimized for GC and headspace analysis, it may not be ideal for LC-MS due to potential ion suppression effects. For LC-MS applications, consider using HPLC or LC-MS grade solvents.
4. What precautions should be taken when handling DMSO?
DMSO readily penetrates skin and can carry dissolved substances with it. Always wear appropriate personal protective equipment (PPE), including gloves and safety goggles, when handling. Work in a well-ventilated area or fume hood.
5. How should this solvent be stored to maintain its purity?
Store the bottle tightly sealed in a cool, dry place away from direct sunlight and moisture. Avoid exposure to air, as DMSO is hygroscopic and can absorb water vapor over time, potentially affecting its performance.
