Princeton Chromatography QB series are densely bonded stationary phases for use in Reverse Phase HPLC.
PrincetonSPHER-100 C18-QB and PrincetonSPHER-100 C8-QB are specifically designed and manufactured to offer maximum ligand density and shielding of the silica surface. In addition, the QB series employs a proprietary end-capping process which further lends these phases to operation over a wide pH range.
PrincetonSPHER QB Series is best suited for applications running from pH 2 – pH 9.5, and is especially effective for low pH work. C18-QB and C8-QB are compatible with USP L1 (C18) and L7 (C8) methods.
