The Petro edition of Zetium

The new element in petrochemicals

The Petro edition of the Zetium spectrometer is designed to deliver reliable and norm-compliant elemental analysis from crude oils to petrochemicals and fuels. 

Like all Zetium spectrometers, the Petro edition delivers reliable analytical performance regardless of the application and excels in areas related to petrochemicals, such as:

  • Sulfur in petroleum products in accordance with relevant ISO and ASTM international test methods
  • Additives in unused lube oils according to ASTM 4927 and D6443 
  • Additives and wear metals in used lube oils
  • Single calibration for many oils, fuels and petrochemicals using the Oil-Trace package.

The Petro edition of the Zetium spectrometer is pre-configured to deliver compliant results from day 1 with the appropriate hardware and your choice of compliance modules, which include factory pre-calibration according to ASTM and ISO international test methods. 

Inclusion of the innovative ED core, makes it the only XRF spectrometer capable of satisfying both WDXRF and EDXRF test methods using a single instrument. Inclusion of the innovative ED core not only delivers dual compliance but can be used to detect unexpected elements in production samples with simultaneous spectrum acquisition.

Connected World

Unleash the potential of your data

Until now, instrument data has too often been stuck in manual records, spreadsheets or site-specific servers. By connecting the Zetium to our Smart Manager and continually analyzing instrument data in the cloud, you can unleash its full potential. This is just one of our digital solutions that are part of Malvern Panalytical's Connected World.

Advanced software and unique application solutions

  • The latest version of our renowned SuperQ software features a new, streamlined user interface, advanced matrix correction algorithms, such as multi-scatter fluorescence, integration of ED deconvolution and integrated intelligence with the Virtual Analyst
  • Guarenteed compliance at start-up with factory pre-calibrated Compliance Modules: 
  • - S in mineral oil (ASTM D2622) 
  • - S in diesel (ASTM D2622) 
  • - S in gasoline (ASTM D2622) 
  • - Additives in lubrication oils (ASTM D6443)
  • Oil Trace eliminates mass/volume dependance and allows different types of petrochemicals to be measured against a single calibration, eliminating the cost of calibration samples and the time required to maintain multiple calibrations

Upgrade packages to meet every challenge

The modular design of the Zetium platform allows optimization of the Petro edition through the addition of upgrade packages that deliver tangible benefits:

  • SumXcore - for reduction in analysis times and identification of unexpected elements in production samples
  • Small Spot Mapping - ideal for the analysis of inorganic inclusions (catalysts, additives, etc.) for process troubleshooting
  • Speed & throughput - for faster sample analysis
  • Robustness & uptime - for tough environments
  • Flexibility - to accomodate sample size variations
  • Performance enhancement - for superior sensitivity
