Polaris - Reversed Phase HPLC Columns. Agilent Polaris HPLC columns offer many polar phase chemistries designed separate mixtures of polar and nonpolar analytes reliably and with excellent peak shapes. The polar-embedded C8 and C18 bonded phases are compatible with 100% water, and offer alternative selectivities while still complying with USP L1 and USP L7. The combination of high carbon load, ultrapure silica, and silanol shielding provides superior peak shape and retention with highly polar samples.
MCX columns are suitable for the aqueous GPC/SEC analysis of strong polyanions such as poly(styrene sulfonate), lignin sulfonate, modified starches, acids, alcohols, and pectins. This sulfonated styrene-divinylbenzene copolymer-based GPC column can be used for sulfonated polymers with molar masses ranging from 100 to 5,000,000 Da and are available in two particles sizes with a range of porosities to meet your polymer analysis needs. MCX columns meet USP L22, tolerate high buffer concentrations, pH 1 to 13, temperatures up to 80 °C, and organic solvents (up to 100% methanol or acetonitrile).
PFG columns are well suited for the organic GPC/SEC analysis of crystalline polymers with molecular weights from 100 to 3,000,000 Da using fluorinated organic solvents. These polar modified silica-based columns are available in two particle sizes, 5 and 7 μm, and four single porosities, 100, 300, 1,000, and 4,000 Å, as well as three different linear/mixed-bed columns, to meet the needs for a variety of organic GPC applications, like crystalline polymers, polyesters, polyamides, polylactides, and POM. Columns produced under DIN EN ISO 9001 quality standards Fittings and integrated diffusers provide low dead volume and efficient distribution of the sample across the entire chromatographic bed for optimal sample injection
