Classical Reversed Phase - C18

 

 

100 angstrom, 120 angstrom and 200 angstrom ultra-high pure silica derivatized with C18 and endcapped. C18 is most preferred because it offers an excellent range of hydrophobic separation power along with high surface area coverage. C18 is most retentive for a wide range of acidic, basic and chelating compounds.
