Model 205 – Sample Transfer
Stripper (STS)
Patented Membrane Technology
Measure H2S in Liquids
PRINCIPLES OF OPERATION:
The ASI/KECO Model 205 incorporates
basic principles covered by patent 5,398,559 and patents pending.
A liquid sample is
allowed to continuously flow past one side of a non-selective
permeable membrane while a carrier gas, H2S-free air or preferably
nitrogen, continuously flows past the other side of the membrane.
Sample components permeate the membrane and are swept away to make a
mixture of gases suitable for analysis. An exclusive & patented
liquid Validation System is available as an option.

TYPICAL APPLICATIONS
Waste Water
Where the dissolved H2S content could be PPBw or at saturation
levels, Model 205 can be easily configured to provide continuous
measurement online.

|
1. MEASURE H2S IN
|
|
|
LIQUIDS.
RANGING:

|
WATER, MEASURE INPUT AND
OUTPUT
STEAM STRIPPER: Measure H2S at
input and output control steam required & save fuel
costs or to regulate maximum through output
CARBON BED
STRIPPER: Same as above
|
|
3. VALIDATION METHOD: |
|
|
Calibration
methods: Permeation tubes can be used to
generate PPM or PPB samples to validate analyzer
response. A liquid or gas trace can be fed into a liquid
or gas stream.
Low maintenance:
Sample Transfer Stripper™ for sampling
radically reduces maintenance for GC,
MS, IR, UV and solid state analyzers. The clean, dry
sample can pay for the sample preparation system by
lowering maintenance time and cost. |
