Targeted Signal
Enhancement (TSE)
Low Concentration Light Gases:
The Measurement Problem
Some process GC applications need more
sensitivity than a conventional GC can deliver.
These applications include ambient air
monitoring, trace analysis of feed streams for
catalyst poisons, trace water analysis for
corrosives, finished product quality, and
environmental water or air quality analysis.

Other solutions exist that are manual or at
least maintenance intensive. They require
consumable resources that are either
inaccessible “in plant” or expensive. And
these solutions are often fragile or require
significant operational tech support.

The Solution: TSE, a Dow Invention
Simply put TSE is an enclosure for chilling a
portion of capillary column at the proper time
in the chromatographic run. The chilled
column traps the component of interest.  
Subsequent heat from the GC oven rapidly
pushes the trapped component into the
measurement system resulting in 10 to
100 times improvement in minimum
detectable levels.
Benefits of A Process GC Application Module TSE
- S/N enhancement for any process GC analyte
- 10 to 100 times improvement in sensitivity
- Reliable, inexpensive and very low maintenance
- Robust and simple
- Can be retrofitted to virtually any process GC
- Laboratory implementation is possible as well
