n-Heptane, 99%, Optima™ for HPLC and GC, Fisher Chemical

Description

High purity and versatile solvent suitable for HPLC, spectrophotometry, and pesticide residue analysis

• Screened for fluorescing contaminants, and UV-absorbing contaminants in the 197-300nm range, to reduce interferences for smoother baselines
• Tested by GC-ECD to ensure minimum halogenated residue levels (≤10 ng/L) to demonstrate suitability for pesticide analysis
• Filtered through a sub-micron filter to remove particulates
• Intended for research use only
