Product Highlight

Residue Plus Grade by CHEMSOLUTE®

Solvents for organic trace analysis and GC-MS analysis. Suitable for many GC detection methods, such as FID, NPD, ECD and MS

Highest purity: Each batch is concentrated to 1/1000 and analysed, filtered through a 0.2 μm filter and filled under inert gas.

Very high detection sensitivity: ppb–ppt levels for critical contaminants, strict limits for residues, water content and volatile impurities.
