DB-5ms non-polar, low-bleed columns feature an improved signal to noise ratio for excellent sensitivity and mass spectral integrity of aromatic compounds.

• Phenyl arylene polymer virtually equivalent to a (5% phenyl) methylpolysiloxane
• Non-polar with very low bleed characteristics, ideal for GC/MS
• Excellent inertness for active compounds
• Improved signal to noise ratio for better sensitivity and mass spectral integrity
• Bonded and cross-linked

J&W DB-5ms features an excellent signal to noise ratio for analytical applications. This improved performance gives better sensitivity and mass spectral integrity. DB-5ms delivers excellent inertness with active compounds. These columns are exact replacements for HP-5TA, and are close equivalents to USP phase G27. DB-5ms is very low bleed, making it ideal for GC/MS.

Max. temperature: −60 to 325/350 °C
