PFASs (per- and polyfluorinated alkyl substances) are a class of almost 10.000 organofluorines. These man-made compounds - also designated «forever chemicals» – are highly persistent and at least some of them tend to accumulate and biomagnify in the environment. For that reason, more and more of these compounds are declared toxic as they pose a risk to human and environmental health. In a joint eLearning session, Theresa Steurer from Metrohm International Headquarters, Switzerland, an...

This eLearning session introduces the operating principle of the SCD, as well as the innovations brought by Shimadzu to improve the productivity and minimize the instrument downtime. You will learn the various features of Shimadzu SCD which make it a reliable tool for analysing sulfur-containing compounds down to the trace level. This is demonstrated with various samples, such as trace thiophene in benzene (ASTM D7011 and D4735), sulfur compounds in light petroleum liquids (ASTM D5623), in na...
ppm water content in LPG and all gas mixtures can now be accurately determined by coulometric Karl Fischer titration. The latest eLearning session presented by ECH Elektrochemie Halle explains in detail how this new ASTM procedure allows you to test ppm water in your laboratory and directly at the sample point. The first question is, why is the water content of LPG and gas so important? Substances with corrosive promoting properties have to be monitored and kept to a minimum. Water is...
When managing equipment in a shared resource facility, it is important to know when your instruments are in use and to define who is allowed to use them. Instrument access control capabilities enable facilities to manage access through both hardware and software mechanisms. With this added layer of security, labs can define when and by whom instruments are used. Further, instrument access control systems that connect directly to shared resource management applications, provide additional bene...
In-service lubricant testing laboratories are faced with increasing demands for profitability and customer satisfaction. To help support these goals, an innovative oil analysis methodology is now available. Regular testing for fuel and glycol in used engine oil by gas chromatography can provide guidance on oil handling. Benefits include: Prevention of unnecessary oil changes Lowered costs associated with enhanced replaceable fluid lifetime Advanced warning of component wear...
Volatile organics like naphtha are amongst the most challenging samples to be analyzed by ICP techniques. Wealth of emission lines originating from the organic matrix and high volatility demonstrate challenges for ICP-OES analyzers. A robust plasma as well as an optical system with high spectral resolution are required in order to routinely quantify trace elements in the low µg/kg range. For specification analysis in the low µg/kg range ICP-MS often is the method of choice as conventiona...
Over the past 20 years, advances in modern ultra-high resolution mass spectrometry have forever changed the expectations of petroleum analyses. Facilitated by advances in ionization methods (that enable molecular-level analysis irrespective of initial or final boiling point), ultra-high resolution Fourier Transform Ion Cyclotron Resonance mass spectrometry (FT-ICR MS) routinely resolves and identifies tens-of-thousands of species (at the level of elemental composition assignment) in individua...
Being a founding member of the Allotrope Foundation - granted the 2017 Bio-IT World Best Practice Award in Knowledge Management - Bayer is implementing strategically the Allotrope Framework to escort scientific data throughout its complete lifecycle from method development over acquisition, processing, reporting, archiving to submission, using a common set of standard tools. Allotrope aims to make the intelligent analytical laboratory a reality – an automated laboratory where data, methods...
Oil industry started long before 1900 and is older than gas chromatography, so test distillation was used for sample analysis and not GC. Fast GC analysis of Diesel and Jetfuel already is a standard but Gasoline is not. Detailed hydrocarbon analysis (DHA) with pattern recognition uses GC analysis input to separate and identify gasoline and blendfeed compounds in 6 minutes. The composite report of DHA is input for the fugacity filmmodel of ASTM method D86 distillation. GC post-run software all...
Non-traditional gasoline additives (NTGAs) like ethyl acetate are being researched as beneficial octane-booster replacements for ethanol and methyl tert-butyl ether. Other octane-enhancing NTGAs, including acetone and N-methylaniline which can degrade automobile engine performance, are sometimes used illegally in gasolines outside the United States and Europe. Unfortunately, monitoring programs relying on ASTM D6730 (Detailed Hydrocarbon Analysis) and ASTM 6839 (Multidimensional Gas Chromatog...
