Modern analysis methods such as LC-MS call for a special solvent quality which has the required purity and which has been tested under application-oriented conditions. Very high purity and very low metal concentrations are features of these products which allow exact interpretations of the mass spectra.

- High UV transmittance
- Low fluorescence
- Excellent gradient baseline
- Trace elements: ≤0.05 ppm per element
- Tested for LC-MS suitability
- Particle filtration (0.2 μm membrane)
- Filled under inert gas
