HPLC Guard Cartridge ZirChrom-PHASE, G20, for 2.1 mm Columnn, Holder ZC-852-00 needed, 3 pc/PAK

ZirChrom-PHASE, unmodified zirconia particles make an excellent support for normal phase LC and phosphopeptide enrichment.

• Stable from pH 1-14 and at temperatures up to 150°C
• Bare zirconia may be used as an extremely stable SEC phase, which does not produce tailing with amines
• A support that may be modified for different selectivity by adding fluoride to the mobile phase
• A very stable, regenerable alternative to fragile and expensive hydroxyapatite for protein chromatography
