Isooctane (2,2,4-trimethylpentane), LiChrosolv® grade, is designed for high-performance liquid chromatography (HPLC) applications requiring low UV absorbance, minimal evaporation residue, and controlled acidity and alkalinity.

LiChrosolv® solvents are filtered through a 0.2 µm filter and manufactured to support reproducible separations under isocratic and gradient conditions. The high UV transmittance and low impurity profile minimize baseline disturbances and gradient effects, ensuring reliable chromatographic performance.

With ≥99% purity (GC), low water content (≤0.01%), and controlled evaporation residue (≤2.0 mg/L), this solvent is suitable for analytical HPLC workflows demanding precision and consistency.

Suitable for:

HPLC (isocratic and gradient methods)

UV detection applications

Analytical separations

Environmental and industrial testing

Fuel and materials research

Flammable liquid — handle and store according to laboratory safety guidelines.
