DX-Series of GC columns, the polyethylene glycol (PEG) DX-1 and DX-4 columns, deliver excellent performance over a wide temperature range.

• DX-1: 90% dimethylpolysiloxane 10% polyethylene glycol
• DX-4: 15% dimethylpolysiloxane 85% polyethylene glycol
• Each Agilent J&W GC column is tested with the tightest industry QC specifications for column bleed, sensitivity, and efficiency to provide you utmost confidence in qualitative and quantitative results
• For details about the QC test conditions including the test probe mixture and the resulting chromatogram, please refer to the Agilent J&W GC Column Performance Summary shipped with each GC column. Because DX series GC columns are not bonded and cross-linked, we do not recommend solvent rinsing

The DX series columns operate within temperature limits of 50 to 250/270 °C.
