Opis

General description

Dichloromethane is a chlorinated hydrocarbon widely used in various analytical techniques, including High-Performance Liquid Chromatography (HPLC), Liquid Chromatography-Mass Spectrometry (LC/MS), and Gas Chromatography (GC). Its unique properties make it suitable for a range of applications in both research and industrial settings.

Application

Dichloromethane is used as a solvent:

• To prepare spectroscopic samples.
• For the dilution of s-diphenylaminostilbene which is used as a reference material for two-photon excited fluorescence (2PEF) measurement.
