Shandong Xinzhiheng Instrument SupplyKB-624 capillary chromatography column，

Basic parameters of KB-624 chromatographic column:

·Medium polarity bonded cross-linked stationary phase

6% cyanopropylphenyl-94% dimethylpolysiloxane column

·Solvent resistant flushing

·EPA 624 and USP G43 dedicated stationary phase

·OVI volatile pollutant specific column

Application:Volatile organic compounds, EPA 624 gas and gasoline segment compounds, USP residual solvents and organic volatile components OVI, alcohols, esters, ethers, residual solvents, chlorinated hydrocarbons, etc

Similar fixed phase:HP-624、DB-624, Rtx-624

Temperature usage range:-20 to 240/260 ℃

The stationary phase of KB-624/DB-624 capillary chromatography column belongs to the medium polarity stationary phase. Among them, cyanopropyl and phenyl provide polar binding sites, while polydimethylsiloxane provides a non-polar skeleton, which exerts certain forces on both polar and non-polar substances as a whole.
Its ability to retain substances is related to their polarity, dispersion force, boiling point, etc. The greater the polarity, the greater the dispersion force, the higher the boiling point, and the greater the retention capacity.
