Agilent J&W HP-5ms Ultra Inert is a (5%-phenyl)-methylpolysiloxane specifically tested for inertness in the analysis of active compounds, including acidic and basic compounds, to meet the growing need for lower detection levels. With very low bleed characteristics, this bonded and crosslinked column is solvent rinsible and ideal for GC/MS. It is equivalent to USP phase G27 and features improved signal-to-noise ratio for better sensitivity and mass spectral integrity.
