Introduction
The Agilent G3451A Gas Sample Selector is a sample preparation device used for
introducing gas samples from multiple sampling bags or cylinders to the GC. An
automated switching valve provides sequential sampling from each connected
sample bag or cylinder.
CAUTION
The gas sample selector is not suitable for analyzing corrosive samples, such as
hydrogen sulfide or ammonia gas (if mixed with water vapor).
The Gas Sample Selector has two available options:
• Bag Version Gas Sample Selector
• Cylinder Version Gas Sample Selector
Both versions support up to eight channels on both the 8890 and 8860 GCs.
