DB-17 GC Columns

Agilent J&W DB-17 a (50%-phenyl)-methylpolysiloxane column of mid polarity. The DB-17 is excellent for confirmation analysis and is equivalent to USP phase G3.

(50%-Phenyl)-methylpolysiloxane
Mid polarity—slightly more polar than HP-50+
Excellent for confirmational analyses
Bonded and cross-linked
Solvent rinsable
Equivalent to USP Phase G3

Similar Phases: Rtx-50, 007-17(MPS-50), SP-2250, SPB-50, ZB-50, AT-50

DB-17ht GC Columns

Agilent J&W DB-17ht provides excellent performance criteria for accurate extended temperature range confirmational analyses. The mid-polarity columns are solvent rinsable and feature polyimide-coated fused silica tubing. With high temperature operation and excellent peak shape delivery, DB-17ht also features faster elution times for high boiling compounds. Stable and efficient manufacturing utilizing high quality components and processes, results in GC columns that feature improved resolution for the effective analysis of triglycerides that remain fully operational over extended temperature limits of 40 to 340/365 °C.

(50%-Phenyl)-methylpolysiloxane
Mid polarity
Extended upper temperature limit of 365 °C
High temperature, polyimide-coated, fused silica tubing
Excellent peak shape and faster elution times for high boilers
Improved resolution for triglycerides
Ideal for confirmational analyses
Bonded and cross-linked and solvent rinsable

Similar Phases: Rtx-65TG, BPX50

DB-17ms GC Columns

Agilent J&W DB-17ms delivers excellent levels of inertness for the effective analysis of active compounds. The column is bonded, cross-linked and solvent-rinsable, and excellent for the analysis of pesticides and other semivolatile analyses. In addition, with very low bleed and midpolarity performance, DB-17ms is ideal for a range of GC/MS applications offering robust and accurate performance every time.

Virtually equivalent to (50%-Phenyl)-methylpolysiloxane
Very low bleed midpolarity, ideal for GC/MS
Excellent inertness for active compounds
Enhanced mass spectral integrity
Bonded, cross-linked and solvent rinsable
The best column for CLP pesticides

Similar Phases: Rxi-17Sil MS, Rtx-50, 007-17, SP-2250, SPB-50, BPX-50, SPB-17, AT-50
