Agilent J&W HP-5ms has very low bleed characteristics that are ideal for GC/MS. The column has excellent inertness for active compounds, including acidic and basic compounds, and improved signal-to-noise ratio for better sensitivity and mass spectral integrity. HP-5ms is also solvent-rinsable because it is bonded and cross-linked. HP-5ms is equivalent to USP phase G27 and delivers excellent performance across a range of applications.
