Stable, Low-Bleed Rtx®-XLB Columns
For Maximum Performance from High-Sensitivity GC/MS Systems
by Gary Stidsen, GC Columns Marketing Manager
•Unique low bleed polymer—ideal for low-level GC/MS.
• Excellent for semivolatiles analysis; equivalent to other “XLB” phases.
•Stable to 360ºC; inert to active compounds.
• In stock, ready for delivery.

and mixed semivolatiles (Figure 1). The selectivi-
ty of Rtx®-XLB columns matches that of DB®-XLB
columns.

Every Rtx® -XLB column undergoes rigorous quali-
ty assurance evaluation for film thickness, bleed
(at 340ºC), inertness, plates per meter, and
retention time indices, to ensure every column
we ship meets exacting performance standards
and performance is reproduced from column to
column. These measures assure you of the high-
est quality GC/MS column on the market.
Figure 2 An Rtx®-XLB column offers low bleed, inertness, and good resolution of semivolatile
environmental pollutants.
Use Rtx®-XLB columns in GC/MS analyses
requiring a low bleed stationary phase at oven
temperatures as high as 360ºC. Applications for
this stable, low polarity phase include
