PLOT GC Columns. GS-Alumina is the most polar alumina phase, consisting of aluminum oxide with proprietary deactivation. It is an excellent general-use column for light hydrocarbon analysis (C1 to C8 hydrocarbon isomers) including C1 to C4 saturated and unsaturated hydrocarbons and cyclopropane from propylene analysis. Alumina columns tend to adsorb water and CO2 which, over time, results in changes in retention time. This column benefits from an advanced, proprietary deactivation process that allows for complete regeneration of a fully moisture saturated column within 7 hours or less at 200 °C.
GS-OxyPLOT is suitable for ASTM methods for a wide range of oxygenates, including ethers, alcohols, aldehydes, and ketones, in complex matrices, such as gaseous hydrocarbons, motor fuels, and crude oil. This GC OxyPlot column offers accurate analysis of ppm/ppb level oxygenates in the C1 to C10 hydrocarbons. GS-OxyPLOT is a good alternative to gas chromatography (GC) columns with gas-liquid phases, such as TCEP, that are often used for similar applications. GS-OxyPLOT has an upper temperature limit of 350 °C and exhibits none of the bleed normally associated with liquid- and siloxane-coated GC columns. Agilent's advanced dynamic coating process virtually eliminates particle generation and detector spiking.
Standard Polysiloxane GC Columns. DB-5 is nonpolar and low bleed, and is available in a range of column dimensions. DB-5 is also bonded, crosslinked, and solvent-rinsable, and has a high temperature limit. It is equivalent to USP phase G27. The DB-5 column is tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency. Features: • (5%-Phenyl)-methylpolysiloxane • Nonpolar, low bleed and with a high temperature limit • Bonded, crosslinked and solvent rinsable • Wide range of column dimensions available • Excellent general purpose column with a wide range of applications • Equivalent to USP Phase G27 • Tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency • Performance Summary shipped with each column
Low Thermal Mass LTM II Columns Agilent J&W LTM column modules combine a high-quality fused silica capillary column with heating and temperature-sensing components for a low thermal mass column assembly. The LTM column module contains a patented design that efficiently heats and cools the column for significantly shorter analytical cycle times compared to conventional air-bath GC oven techniques, while also using less power. Modules for 7890 Series GC systems are available in a wide variety of WCOT and select PLOT column configurations. The LTM II transfer line module has two heated, temperature-programmable tubes (transfer lines) through which the column leads pass, to prevent cold spots between the oven and the column assembly. Each module attaches to a transfer line module, and the resulting assembly inserts into slots in the LTM oven door.
LTM column module. This format is only compatible with Agilent Low Thermal Mass Series Rapid Heating/Cooling (LTM) Systems.
Ultra Inert GCColumns. HP-1ms Ultra Inert features exceptionally low column bleed and is designed to deliver consistent column inertness performance. They are individually tested with an Ultra Inert 1ms test probe mixture according to the strictest industry QC standards to ensure excellent signal-to-noise ratios and high-quality peak shapes for challenging active analytes. These columns deliver high levels of accuracy and results integrity in a range of applications, with minimal compound adsorption or degradation. Features • Individually tested with Ultra Inert 1ms test probe mixture • Consistent column inertness performance • Exceptionally low column bleed • Great peak shapes for challenging active analytes • Excellent signal-to-noise ratios • Minimum compound adsorption or degradation • Supports 0.18 mm id column configuration for higher sample throughput • Tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency • Performance Summary shipped with each column
GC column. HP-20M are polyethylene glycol (PEG) columns equivalent to USP phase G16. Their temperature range of 60 to 220 ºC is ideal for alcohols, free acid, ether, glycol, and solvents. HP-20M are not bonded or cross-linked and so solvent rinsing is not recommended.
Similar Phases: OV-101, SP 200, DB-1, HP-1 Temperature Range: 0 to 280 ºC Applications: Amino acid, derivatives, essential oils
