The ProCeas H2S is a complete pre-calibrated laser infrared spectrometer
for low level detection of H2S in natural gas and liquefied natural gas (LNG).
The ProCeas H2S uses the patented OFCEAS (WO 03031949) IR Laser technology for enhanced specificity,
selectivity, accuracy and stability (no instrumental response drift.)
The ProCeas H2S uses a patented low-pressure sampling system (WO 2010058107) enabling low-cost installation
thank to non-heated lines* and reduced maintenance.
The ProCeas H2S is a complete, reliable, robust, low-cost and easy-to-use solution for the H2S analysis natural
gas processes.

DIRECT MEASUREMENT
No sample pre-treatment.
OFCEAS technology associated with low pressure sampling enables direct measurement. The low pressure in
the sampling system removes any risk for chemicals
adsorption/desorption and condensation in the line.
NO INTERFERENCE
OFCEAS technology associated with low pressure
sampling provides exceptional selectivity, enabling simultaneous multi-component measurement without
interferences, regardless of the matrix.
NO RE-ZERO; NO DRIFT
The zero information is contained in the signal, enabling
automated and intrinsic re-zero of the analyzer.
EASE-OF-USE
The ProCeas is pre-calibrated for your application. Initially packaged in a standard 19”rack, it includes a touch
screen interface and on-board PC for local / remote
control and real time display / recording of results.

EASE-OF-INTEGRATION
The ProCeas allows digital (Ethernet, RS485, RS232,
ModBus), analog and TDR I/O’s.
ROBUSTNESS
The ProCeas contains no optical moving parts and was
designed and built strictly for industrial and on-board
mobile applications.
LOW MAINTENANCE
High MTBF.
In addition to containing no moving optical components,
the IR sources (telecom type laser) are characterized by
MTBF’s of 5 years.
CLEAN LINES / FILTERS
The low pressure sampling system enables low flow rates
(3-9 L/h) without degrading response time. Accumulation
of contaminants lines and filters is greatly reduced.
SAFE
ATEX compliant configuration available.
