As the leading infra-red based quality testing system for biodiesel, the QTA System analyzes over 3000 biodiesel samples per month for production facilities producing a combined total of over 750 MM gallons. Biodiesel facilities having a QTA System receive B100 analysis results for six properties in less than 2 minutes, plus additional analyses for in-process samples, oils & fats, crude glycerin, and recycled methanol – all in less than 2 minutes.
Biodiesel analysis using traditional ASTM methods is time consuming and challenging. It involves sample preparation, the use of reagents, and time – usually at least 40 minutes per sample. Since 2006, QTA has been using ASTM data from hundreds of biodiesel samples to build highly robust calibrations for all the materials used in a biodiesel production facility: raw material, finished product, in process samples and byproduct. These calibrations enable you to analyze B100 and other materials quickly, accurately and easily using the QTA system. The QTA system calibrations encompass all major raw material types, including Soy, Canola (Rapeseed), Vegetable, Poultry, Beef tallow, Choice White Grease, Sunflower, and Waste Vegetable Oil. Because Eurofins QTA calibrations are based on this wide cross section of raw materials, as well as a wide variety of different production processes, Eurofins QTA biodiesel calibrations are more robust than others and their predictions are more accurate.

Here’s How It Works
An infrared spectrometer is placed at your site. Using a computer connected both to the spectrometer and to the internet, you log on to the Eurofins QTA interface, using a secure user name and password. Upon log in, you have access to a library of calibration algorithms for biodiesel materials. You enter a sample ID on your computer, clean the sampling surface, then place one drop of the sample on the spectrometer and press analyze. The spectrometer checks for cleanliness, then collects a light spectra, digitizes it and sends it over the internet to the Eurofins QTA central processor. The central processor uses the biodiesel algorithms to interpret the light spectra, then sends a result back to your computer. The entire process takes less than 2 minutes, is non-destructive and usually requires no sample preparation.
