OptiFuel: A Game-Changer in Rapid Fuel Analysis

Mar 15 2017 Comments 0

Fuel products can get mixed and contaminated while being transported for distribution, so they need to be tested and certified continuously to guarantee its quality. The process of analysing the refined fuels needs to be done quickly and effectively.

As part of this quality control process, several physical and chemical properties are measured depending on the type of the fuel. The process involves tapping small amounts of fuel samples from the tanks, pipelines or containers and measuring them on single or multiple analysers. Due to the nature of fuel transportation where there is a constant flow of incoming and outgoing fuel, it is essential to have all these measurements done quickly, economically and with the least amount of personnel training. Analysing these properties using individual direct measurements involves formidable amount of time, labour and expenses.

The IR technology used to measure these properties has evolved over time from a one-parameter dispersive to a multi-parameter dispersive to FT-IR (Fourier Transform Infrared Technology), which provides a significant advantage over dispersive spectroscopy due to its ability to capture molecular information spanning the entire IR range.

For almost 20 years PAC has been at the forefront of fuel analysis with its robust PetroSpec products. By using powerful and more versatile FT-IR technology, we are now combining the best of our GS PPA, TD PPA and QuickSpec capabilities into one analyser, and adding many more features. OptiFuel is not a mere replacement of our legacy products, it is the best FT-IR dedicated fuel analyser in the market.

The new OptiFuel can measure physical & chemical properties of Gasoline, Diesel or Jet Fuel in seconds, all in one system, with a one push of a button. It is so easy, that the user doesn’t require any kind of training to operate the analyser.

With its vibration-resistant advanced cube corner design and humidity-resistant ZnSe optics, OptiFuel provides high and reliable performance crucial for quality control checks. The spectral shift is virtually non-existent, due to its extreme temperature controlled laser reference design. Its calibration is quickly done through a one-step transfer/cloning procedure and it lasts for years. Preventive maintenance can be easily done on-site.

OptiFuel is delivered from the factory with high quality chemometric models, built using hundreds of real samples acquired from top oil & gas producers across the globe. Thanks to its advanced FT-IR technology and user-friendly GUI (graphical user interface), the opportunities for future expansion of these models are endless.

Optifuel comes with an industry leading 10-year warranty on its modern Michelson interferometer and a 5-year warranty on its IR light source, so users can rest assured that they will have near zero downtime on the analyser.

OptiFuel is in compliance/correlation with most of the standards:



  • Benzene: ASTM D6277, EN 238
  • FAME: ASTM D7371, D7806, EN 14078
  • Oxygenates (MTBE, ETBE, TAME, DIPE, Methanol, Ethanol, tert-Butanol): ASTM D5845
  • Density: ASTM D777


ASTM D2699, D2700, D5191, D86, D4814, D6839, D6839, D6839, D6839, D613, D4737A, D86, EN ISO 3405, EN 14078, EN ISO 5164, EN ISO 5163, 13016/1, 3405, 22854, 22854, 22854, 22854, 5165, 4264, SGS M2533 & others

With its industry leading warranty, proprietary design with no moving parts in the measurement cell and extreme ease-of-use, OptiFuel offers an ideal solution for quick and easy solution to measure fuel properties with minimal training, from day one.
