OI Analytical`s (USA) new S-PRO 3200 brochure contains information on
a GC system for selective, highsensitivity measurement of sulphur
compounds in gas-phase samples such as natural gas, ethylene, propylene, liquefied petroleum gas (LPG), and beverage grade CO2.
Known and unknown sulphur compounds can be measured from low ppb to ppm levels, and total sulphur content is reportable as the sum of individual peaks.
