Advanced X-Ray Transmission (XRT) Gauge for Crude Oil, Marine Bunker Fuel and Blending Operations
Rigaku's (USA) NEX XT is the next generation process gauge for high-level sulphur measurement (0.02% to 6% S) of crude, bunker fuel, fuel oils, and other highly viscous hydrocarbons, including residuums.
This versatile, compact and robust X-Ray Transmission (XRT) process gauge is specifically optimised for the sulphur analysis needs of refineries, pipelines, blending operations, bunkering terminals and other storage facilities. Applications include bunker fuel blending to meet MARPOL Annex VI sulphur restrictions, interface detection of different grade fuels delivered via pipelines, refinery feedstock blending and monitoring, and the quality monitoring of crude at remote collection and storage facilities.
XRT can measure sulphur (S) from 200 ppm to 6 wt% at up to 1480 psig and 200°C and offers a data update every 30 seconds. This user-friendly system has reduced standards requirements, no routine maintenance, sample condition, recovery system or radioisotopes Among its other key features are a simplified user interface, automatic density compensation, automatic water compensation, password protection, and standard platform for communicating sulphur, density, and water content to a plant-wide DCS.

Reader Reply Card No New User-Friendly GC/MS Interface
Joint Analytical Systems GmbH (Germany) has introduced a user-friendly GC/MS interface which enables a 100% tool-free column exchange without MS venting. A narrow, special deactivated transfer tube is used as a connection between the analytical column and the MS source.
Swap’n Go is an easy-to-use, self-installable robust device, which enables the operator to exchange capillary columns fast and simple - completely tool-free and without MS venting. Unscheduled disruption in analytical work due to column exchange is avoided.
The analytical column (200, 250 and 320 µm ID) is fixed only hand-tight to the Swap’n Go adapter by a special designed
JAS-Tight nut sealed with a JAS-Tight ferrule. The column is also connected only hand-tight to the S/SL injector by means of a special JAS injector adapter. Instrument-specific systems are available for Agilent and Thermo instruments.

Innovative Technology for Water Quality Monitoring
OI Analytical’s new 9210 On-line TOC Analyzers support continuous on-line monitoring of organic contaminants in water streams for regulatory compl- iance monitoring and optimisation of water treatment processes. Two models (the 9210e and 9210p) are offered to address a range of process situations and water monitoring applications.
The 9210e On-line TOC Analyzer is based on an innovative “reagentless” electrochemical oxidation technology OI developed for use by NASA on board the International Space Station. Special boron doped diamond (BDD) electrodes produce hydroxyl radicals, peroxides, and ozone that efficiently oxidise and convert organic compounds into CO2
for measurement by a solid- state non-dispersive infrared (SSNDIR) detector to calculate the TOC content.
The 9210p On-line TOC Analyzer uses proven heated persulfate wet oxidation technology for applications involving regulatory compliance monitoring and reporting. Virtually all organic compounds dissolved in water can be oxidised with high efficiency by this technique. The 9210p also employs a SSNDIR detector to measure the CO2
released during wet oxidation for calculation of TOC content.
Results for each sample are shown on the touch-screen display of the 9210 analyzer and can be output to a Supervisory Control and Data Acquisition (SCADA) system, PC via Ethernet connection, relay/alarm closure, or as a 4-20mA analogue signal.
The touch-screen display has a Windows® CE-based user interface to simplify instrument set-up, and access to data, trending, and diagnostic screens.
Both 9210 On-line TOC Analyzers are specifically engineered for operation in process environments. The instrument can be wall or rack mounted in indoor or shade-sheltered outdoor locations. The 9210 instrument housing has a sealed electronics compartment designed to meet NEMA 4X and IEC class IP56 standards. A locking hinged door provides access to fluid components.

OI Analytical is a leading provider of instrumentation for selective, high sensitivity measurement of sulfur compounds in petrochemicals.
The PFPD – Pulsed Flame Photometric Detector measures known and unknown sulfur compounds in liquid-phase samples from low ppb to ppm levels, and total sulfur as the sum of all sulfur compounds. Simultaneous sulfur and hydrocarbon chromatograms from the PFPD provide a unique analytical capability for ultra-low-sulfur fuels.
The S-PRO 3200 GC system is equipped with special components to measure sulfur compounds in gas-phase samples such as; natural gas, propylene, ethylene, and liquefi ed petroleum gas (LPG).
