Crude oil is the lubricant of the world’s economy. Numerous parameters define the quality of petroleum products and their derivatives. Metrohm’s new brochure Petrochemical Analysis is a summary of the most important of these quality parameters and the methods used to check them. Metrohm’s complete know-how (instruments and applications) on petrochemical analysis is accessible on the new webpage petro.metrohm.com.

Petrochemical Analysis, which can be ordered free of charge, draws on the company’s comprehensive know-how in assuring the quality of petroleum products. Using the most important national and international standards (ASTM, DIN, ISO, UOP …) as a basis, Petrochemical Analysis suggests methods as well as instrumentation suited best to check crucial parameters such as

• base number (TBN)
• acid number (TAN)
• hydroxyl number
• chlorine content
• water content
• oxidation stability
• elemental sulfur and sulfuric compounds
• heavy metals
• pH value
• and many more

Methods covered include potentiometric, colorimetric and Karl Fischer titration (volumetric and coulometric), oxidation stability, ion chromatography, voltammetry, atline and online process analysis. Petrochemical Analysis is a highly valuable tool for anyone who is involved in the professional quality assurance of petroleum products.

The easiest way to access Metrohm’s complete know-how on petrochemical analysis is the website petro.metrohm.com. Here you can find a multitude of applications as well as information on analytical instrumentation for the petrochemical industry. Downloads are free of charge.

Ion ChromatographyIon chromatography, also known as ion exchange chromatography, is a high-performance liquid chromatographic technique used for the separation and identification of ions or polar molecules in a sample, including proteins, nucleotides and amino acids. Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors. Find the best ion chromatography equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.VoltammetryVoltammetry is a sensitive analytical technique for elemental detection. In a voltammeter the current is measured in the system whilst the voltage is varied. Usually 3 metal electrodes are required including the reference, auxiliary and working electrodes. In polarography, a subclass of voltammetry, the working electrode used is a dropping mercury electrode (DME). The 2 main types of voltammetry are cyclic and linear sweep voltammetry.Robotic InstrumentsRobotic instruments can be used for high-throughput automation of many lab processes. Such processes use instruments for assays like cell based assays and ELISA, for sample preparation like shakers, centrifuges and incubators, and for analysis such as sequencing and western blot analyzers. Useful features of robotic instruments include speed, reproducibility, barcode readers, software and automation.Automated Liquid HandlingAutomated liquid handling equipment is used to mix, dilute and dispense allotted volumes of liquid into microplates and other vessels automatically. The robotic, liquid handling arms can dispense from single channel to 3456 multichannel as well as operate nanoliter dispensing, enabling high throughput of samples. Find the best automated liquid handlers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.TitrationTitration is an analytical technique for determining substance concentration in a solution. For titration consider a manual or automated system, volumetric or coulometric reagent addition and indication by a potentiometer, spectrometer, turbidometer or by the Karl Fischer method. Other features of titration to consider include burettes, reagents, concentration range, reaction time and autosamplers.Fuel and Energy
