New Sulphur Analyser to Complete the X-Ray Sulphur Analyser Line
Tanaka Scientific Limited (Japan) launched their new total sulphur analyser for petroleum products. Model fxe-400s is Tanaka’s latest EDXRF sulphur analyser equipped with an optimised X-ray pass and a high precision pre-amplifier developed through collaboration with Japan Atomic Energy Agency (JAEA). JAEA’s simulation technology and high speed/high precision electronics have been utilised.
High Precision: Thanks to the simulation, a filter for unwanted signal from X-ray tube was optimised. Together with the adoption of newly-designed low background proportional counter, S/N ratio of the sulphur signal area improved significantly. The fxe-400s attained 5 mg/kg of LOD with low power X-ray source(0.85W).
Easy operation: Interactive computer program, wide colour LCD screen, and ergonomically designed user interface help ease of operation.
With the addition of this new model, Tanaka now has a full line up of X-ray sulphur analysers to cover the varied requirements in petroleum industry's., including requirements for Ultra Low Sulphur Diesel fuels, Gasoline, Fuel oils and Marine fuels.

Laboratory Testing and field results have proven that SilcoNert 2000 from Silkotek (USA) treated sampling and testing equipment is inert to mercury, mercury species, H2S, mercaptans, and many others.
SilcoNert 2000 is an inert coating that can be applied to the most intricate surfaces while maintaining precise tolerances found in monitoring and instrumentation. SilcoNert 2000 can be applied to most components found in mercury and sulphur sampling systems, including: housings, impingers, tubing, fittings, valves, filters, sample cylinders and storage containers, downhole samplers and flare gas and stack probes.

Solid Phase Extraction Products: Te Quality You Require and the Performance You Demand
A solid phase extraction (SPE) brochure, containing product information and selection guides, is available from Supelco (USA). SPE is a form of step-wise chromatography designed to extract, partition, and/or adsorb one or more components from a liquid phase (sample) onto stationary phase (sorbent or resin). Using liquid chromatography principles to control selectivity, SPE provides the sample clean-up, recovery, and concentration necessary for accurate analysis. It has become the most powerful technique available for rapid and selective sample preparation (prep) prior to analytical chromatography. In addition, SPE extends a chromatography system’s lifetime, improves qualitative and quantitative analysis, and by changing an analyte of interest’s original matrix environment to a simpler matrix more suitable for subsequent analysis, the demand placed on an analytical instrument is considerably lessened.
The multitude of available phase chemistries can be packed into an array of hardware formats such as glass tubes, 96-well plates, preparative SPE Büchner funnels and dispersive SPE, and can be processed using dedicated vacuum manifold accessories.
Reader Reply Card No 86 Lonestar Portable Crude Oil Quality Analyser Launched
Owlstone Inc (UK) have announced the launch of their Lonestar Portable Crude Oil Quality Analyser, an instrument that can be used by any operator for rapid, at-line detection and quantification of crude oil contaminants including methanol, hydrogen sulphide scavengers (triazines), monoethanolamine (MEA) and organic chlorides.
Contaminants in crude oil can cause expensive problems at downstream processing plants. Compounds such as methanol can impact refinery
water treatment facilities; triazine based H2S scavengers can cause corrosion and fouling in downstream equipment. Utilising Owlstone's proprietary Field Asymmetric Ion Mobility Spectrometry (FAIMS) technology, Lonestar can be used at-line, to analyse crude oil samples, ensuring the quality of crude before it reaches the refinery.
Commenting on the launch of the Lonestar, Owlstone co-founder, Billy Boyle said, "There are plenty of laboratory instruments, which require specialist staff, big capital outlays and long turnaround times in measurement. With the launch of Lonestar we are bringing the laboratory to the field, with a cost effective instrument that can be used by any operator".
A major advantage of the Lonestar system is that no special sample preparation is necessary. The crude analysis itself takes only 7 minutes, after which Lonestar provides a simple concentration value of the target contaminant. Lonestar can also be easily configured to provide a warning if the measured concentration is outside of pre-designated limits.
Lonestar represents a breakthrough in simple, portable crude oil assay instrumentation, which has already been shipped to numerous leading oil producers and oil service companies.
