Biodiesel: Contaminants and Quality Control

Biodiesel Production and Quality

Single-shot biodiesel analysis: nearly instantaneous typification and quality control solely by ambient mass spectrometry.

Using a simple and easily implemented desorption/ionization mass spectrometry technique, a tiny droplet of biodiesel placed on the surface of a sheet of paper is analyzed directly and nearly instantaneously under ambient conditions. No pre-separation or sample preparation is required, and clean mass spectra are obtained with great simplicity. In the positive ion mode, easy ambient sonic-spray i...

Diesel Fuel Derived from Vegetable Oils, Vi: Specifications and Quality Control of Biodiesel

Due to the rising importance of biodiesel as alternative fuel in many countries, it is absolutely necessary to establish standards for the description of the quality of the product. The parameters and the corresponding threshold values defining the quality of rapeseed-oil methyl esters (RME) used as biodiesel according to the latest Austrian standardization (O-NORM) are presented and discussed....

Biodiesel Analysis for Inorganic Contaminants Using the Optima 8000 ICP-OES With Flat Plate Plasma Technology

In the Unites States, the production of biofuels is primarily driven by the use of corn for ethanol and soy beans for biodiesel. Unfortunately, the competition for these raw materials has had an adverse effect on the price of food stuffs produced from these crops. The search for alternative and more efficient sources of raw materials for biodiesel production is ongoing. Biodiesel can be made fr...
