5% diphenyl/95% dimethyl polysiloxane)
Rtx®-G27&Rtx®-G43
• Application-specific columns, designed for analysis of residual solvents inpharmaceutical products.
• Meet all requirements of USP467.
• Integra-Guard™ guard+analytical column eliminates connectingproblems and leaks.
• Rtx®-G27 thermally stable to290°C; Rtx®-G43 thermally stable to240°C.
SomeUSP467methods require theuse of a guard column.Our Integra-Guard™ integrated guard
column systemmakes this an easy task.

Rtx®-BAC1
(fused silica)
Rtx®-BAC1/Rtx®-BAC2
(proprietaryCrossbond®phase)
• Application-specific columns for blood alcohol analysis, achievingbaseline resolution in less than
3minutes.Also excellent for abused inhalant anesthetics,
γ
-hydroxybutyrate (GHB) /
γ
-butyrolac-
tone (GBL), glycols, and common industrial solvents.
• Rtx®-BAC2 confirmation columnprovides four elutionorder changes under the same conditions.
• Rtx®-BAC1 stable to260°C,Rtx®-BAC2 stable to240°C.
These columns achievebaseline separationof all blood alcohol compounds inblood, breath, orurine
in less than 3 minutes, under isothermal conditions. Isothermal analysis increases productivity by
eliminating the need for oven cycling. Confirmation is easily achievedwith this tandem set because
there are four elutionorder changes between the two columns.
