Detailed group analysis
SI-PIONA provides a method for detailed group type analysis of gasoline and petroleum naphtha containing hydrocarbons with boiling points between -42 °C (propane) and 216 °C (n-dodecane).
To achieve this, the hydrocarbon compounds are divided into 94 sub-groups which are assessed in addition to six oxygenates (Methanol, Ethanol, tert-Butanol, tert-Butylmethylether, tert-Butylethylether and tert-Amylmethylether).
The main components of the SI-PIONA software package are:
• A MS library containing approximately 1,100 mass spectra of the different compounds present in gasoline/naphtha.
• An RI database of approximately 400 compounds for correct isomer identification.
• Software for automated peak identification and quantitation.
• Software for reporting the main PIONA groups.
The SI-PIONA program can be applied to quadrupole and magnetic sector instruments. Direct access of data files from Finnigan MAT, Hewlett-Packard, VG, MicroMass, Thermo Scientific and Fison instruments is included in the software.
*EASYQUAN and SI-PIONA were developed by Kjell Urdal during his time at SINTEF Applied Chemistry and are now sold and supported by APT on behalf of SINTEF.
