The Thermo Scientific™ SOLA™ iQ Online Sulfur Analyzer measures total sulfur content in liquid or gas phase samples to optimize processes, improve profitability, and comply with regulations.
The SOLA iQ Analyzer, which uses unique Pulsed Ultraviolet Fluorescence (PUVF) technology and the proven Pyrolysis system, builds on the success of the SOLA II range of total sulfur analyzers, which have thousands of units installed for measuring total sulfur concentration at the world's leading oil and gas companies.
The SOLA iQ Online Sulfur Analyzer reduces the need for costly and time-consuming laboratory sampling to determine total sulfur content in refinery products such as gasoline, diesel, kerosene, and jet fuel, as well as several process gas samples such as natural gas, NGL, and SynGas. The SOLA iQ Analyzer provides an online adaptation of ASTM D5453, D6313, D6222, and ISO 20846.
