A Pre-Calibration Program for Quantitative Analysis of Oils Using XRF

Sep 02 2008 Read 989 Times

Petrochemical regulations are becoming stricter demanding lower levels of quantification for key elements such as sulphur (S), Pb etc. WDXRF technique, which has proven its ability to produce highly reliable and repeatable results, is being increasingly solicited for this analysis. Thermo Scientific (USA) ARL OPTIM`X and ARL ADVANT`X Series of XRF
spectrometers have been shown to be compliant with various norms such as ASTM D2622, ISO 14596 etc., thanks to their high sensitivity and stability. In addition, various other elements used as additives in lubricants, residual oils or wear metals need to be analyzed in a typical blending control station or in a central laboratory. Our company has developed PetroilQuant, a unique pre-calibration program to help analysts in the petrochemical and petroleum industries meet
these requirements. PetroilQuant is designed for use in conjunction with Thermo Scientific ARL OPTIM`X and ARL ADVANT`X Series X-ray spectrometers and is capable of quantifying up to 24 elements in a variety of automotive fuels, lubricants and heavy residual oils both quickly and cost-effectively.
With PetroilQuant, X-ray spectrometers are calibrated for a series of elements in a wide dynamic range covering multiple oil matrices. PetroilQuant requires no analytical expertise and provides a "ready to run" analytical package for beginners as well as advanced users of Thermo Scientific XRF instruments. Further refinement or fine tuning for specific elements can always be achieved either in the factory prior to shipment or after installation using customer`s own
set of samples.
In addition to sulfur in automotive fuels, PetroilQuant covers other elements generally needed for blending control of fresh lubricants such as Sodium (Na), Magnesium (Mg), Silicon (Si), Phosphorus (P), Chlorine (Cl), Potassium (K), Calcium (Ca), Zinc (Zn), Molybdenum (Mo), Bromine (Br) and Barium (Ba).
PetroilQuant can be installed on ARL OPTIM`X equipped with SmartGonio™ and is best suited for key elements such as sulfur (S) and lead (Pb) in automotive fuels and lubricants.
This program can also be installed on the ARL ADVANT`X Series with SmartGonio or with the Universal Goniometer for a more extended range of elements including residual oils and more demanding concentration limits. In addition, PetroilQuant facilitates further improvements of accuracy on specific elements whenever needed.
