Agilent J&W Specialty Columns
Agilent J&W Specialty GC Columns
Agilent J&W Specialty Columns are built for applications where a general-purpose GC phase isn’t enough—when you need targeted selectivity, improved recovery for active compounds, higher temperature capability, or method-driven performance for regulated workflows. These specialty chemistries help resolve difficult coelutions, stabilize peak shape, and increase confidence in trace-level quantitation across complex sample matrices.
This category includes WAX/PEG oxygenate columns (DB-WAX, HP-INNOWAX, Carbowax 20M families), acid-modified FFAP phases for organic acids and free fatty acids, and application-specific column families designed around petroleum, pesticides, PAHs, volatile or semivolatile panels, and biodiesel/FAME profiling. You’ll also find specialty formats such as high-temperature columns for high-boiling analytes, metal-clad columns for rugged handling, and PLOT columns for permanent gases and very light hydrocarbons.
