The lead acetate tape method for the detection of hydrogen sulfide (H2S) in gaseous
streams is based on the established principle that H2S reacts specifically with lead acetate
to form a lead sulfide brown stain. The concentration of H2S is directly proportional to the
rate of change of staining on the lead acetate tape. This principle is the basis for a number
of ASTM methods.
Galvanic Applied Sciences manufactures a complete line of “state of the art” analyzers
for lab and process applications which employ sulfur chemiluminescence technology to
detect sulfur in a wide variety of hydrocarbon samples. These analyzers measure total
sulfur in liquids and sulfur components via gas chromatography in vapor samples.
The PLGC II is a compact and low cost gas chromatograph equipped with a universal
thermal conductivity detector. The unit offers a wide range of applications where
hydrocarbon gas or fixed gas analysis is required, such as in BTU measurement for the
natural gas industry.
The Galvanic Applied Sciences Micro PL-GC analyzer is designed to provide a low cost, low maintenance
measurement of energy content in natural gas. It can replace manual or periodic sampling
and provides component mole percent analysis as required for AGA8 calculations. Since the Micro
PL-GC is a gas chromatograph, it can be used in many measurement applications where an isothermal
TCD scheme is suitable.
GAS Micro is a universal electronic platform, software interface, and mechanical assembly designed to be configurable
for application as an Electronic Volume Corrector (EVC) and/or Electronic Pressure Recorder (EPR), or 3-Channel
Electronic Recorder (ER).
The sensor is based on true dual wavelength infrared
technology with no moving parts. The result is
a low drift, high accuracy with a fast response
time and low power consumption.
The WIM (Wobbe Index Meter)
measures the Wobbe Index and the Air Demand of natura! gas, refinery fuel gases and biogas. The measuring principle is based on the
analysis of the oxygen content in the flue gas after combustion of the sample.
