Agilent DB-5 GC Columns
All pictures shown are for illustration purpose only. Actual product may vary.
Agilent J&W DB-5 is a non polar and low bleed phase, and is available in a range of column dimensions. DB-5 is also bonded, cross-linked, and solvent rinsable, and has a high temperature limit. It is a general purpose column, suitable for a wide variety of applications, and equivalent to USP phase G27. The DB-5 column is tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency. A number of modified phases are available to allow for different uses, including GC/MS and trace level analysis:
DB-5 – high quality, non polar, general purpose columns
DB-5.625 – specially processed to exhibit excellent inertness for EPA semivolatile methods 625, 1625, 8270, and CLP protocols

DB-5.625 GC Columns
Agilent J&W DB-5.625 non polar, bonded columns are specially processed for excellent inertness and selectivity as a standard column for EPA semivolatile methods 625, 1625, 8270, and CLP protocols. The DB-5.625 features high temperature limits with excellent thermal stability and low bleed. Special tested to reliably surpass EPA performance criteria for semivolatiles. The columns are inert and neutral for effective use with basic, neutral and acidic compounds, and are also solvent rinsable.
