24 Analytical Instrumentation Mercury and Petrochemicals P S Analytical –
Experience, Performance, Reliability and Support The presence of mercury (Hg) in petrochemical samples is very bad news. Even at ultra-low concentrations mercury is corrosive to gas plant components and infrastructure, poisonous to expensive downstream precious metal catalysts and exposes workers to highly toxic workplace conditions.
It’s no wonder that petrochemical plants and refi neries spend vast sums every year removing even small concentrations of Hg from their precious gas and liquid sample streams. It is also no wonder that they wish to maximise the effi ciency of their Hg removal systems and to achieve this, highly accurate and sensitive monitoring and measurement of Hg is required. Sub part per trillion sensitivities is the normal requirement.
That’s where PS Analytical (PSA) comes in.
For over 35 years PSA has been at the forefront of trace Hg determinations. PSA partners with many companies to monitor and help manage this Hg removal process. This partnership happens from the research bench through to production with PSA taking a pivotal role in ensuring successful removal technologies are deployed in the real world.
PSA have analysers to suit all aspects of the monitoring and analysis of Hg, including laboratory instruments and on-line analysers for gases and liquids. More recently PSA have provided solutions for speciation (fractionation) analysis and also waste water systems associated with petrochemical processes.
Employing Atomic Fluorescence Spectroscopy as the means of detection the PSA analysers provide ultimate detection performance. With literally thousands of systems in the fi eld today, and support networks in Europe, USA and SE Asia, PSA offers the ideal package of performance, reliability and support.

AccuStandard is pleased to announce the launch of a new product line of Certifi ed Reference Materials (CRMs) for the determination of Sulfur content in a new and emerging type of fuel, renewable diesel fuel.
Renewable diesel fuel, also known as sustainable fuel, is a new grade of diesel fuel that is made from vegetable oil (or any biomass feedstock) by a process of hydrogenation. The end product is a fuel composed of different hydrocarbons that meets the criteria of Diesel Fuel per ASTM and EPA.
One of the main characteristics of this type is the ultra-low native sulfur content compared to the conventional diesel fuel. This offers a great analytical advantage by reducing possible native sulfur interferences especially when calibrating using a low sulphur concentration CRM.
AccuStandard SRD-CAL-SET includes 21 CRMs from as low as 5 µg/g Sulphur concentration introduced as n-Butyl Sulphide available to purchase as a SET or individuals for the analysis of sulfur following different ASTM methods such as D2622, D5453, D6334, D6445 and others.
