Oxidation stability of biodiesel (fatty acid methyl esters, FAME) and biodiesel blends 04 The use of alternative fuels made from renewable plant sources has become more widespread in recent years and is likely to increase in the future. Besides other alternative fuels such as ethanol, methanol or biogas (methane), fatty acid methyl esters − also known as biodiesel, RME (rapeseed oil methyl esters) and FAME − have become another important renewable energy source. Fatty acid methyl esters are usually obtained from oil seeds and are used automotive fuel either in their pure form or mixed with...

Start buttons on the instrument Next to each measuring position there is a button with which determination can be started immediately after the sample has been placed in the heating block. The start button is completely sealed on the outside, so no liquids such as sample or water can enter. Triggering is achieved with the help of capacitive finger detection and also works with gloves. Instrument display The status of the instrument and of each individual measuring position can be watched on the color instrument display. It shows the current temperature of the two heating blocks, the gas...

StabNet – modern software for stability measurements 08 StabNet is the modern and user-friendly software for carrying out stability measurements and archiving the measurement data. The characteristic features of StabNet are its ease of use and flexibility. This is evident already in the «Workplace» part of the program, where the day-to-day work is done. Here users will find all the elements that are needed to carry out determinations. The structure of the «Workplace» shows the setup of the 893 Professional Biodiesel Rancimat with its 2 heating blocks and the 8 measuring positions.

Method | Standard rnetrwd biodiesel_ For each heating block it is possible to load an individua method in which, amongst other things, the tempera- ture and gas flow are defined. The heating is switched on manually in the «Workplace» part of the program. The heating can also be started automatically, and very con- veniently, at a defined time with the help of a timer; the nstrument will then be ready for use right on the start of For each measuring position on the instrument there is a live display in the «Workplace» part of the program The flashing Start/Stop button indicates a...

Recalculation of determinations Should it ever be necessary, determinations can also be processed at a later time, either by recalculation with different evaluation parameters or by manual evaluation of the curve with tangents. The original data are not lost. All versions of the determination are archived. Using the History function it is possible to restore the original version or any interim version or the final version at any time. Report creation The Report Generator offers complete freedom when it comes to creating the analysis report, whether it be an individual report with all the...

Other helpful database functions Today entering a result in a table is simply not enough Frequently, measurement results need to be set out as statistics and graphs. StabNet also supports this step Statistical calculations Confirmation of relevant results usually requires multiple as the mean value and the absolute and relative standard determinations. StabNet offers the possibility of linking 2 deviations, are then calculated automatically in addition or 4 replicate determinations together statistically. At the to the individual result end of the multiple determinations, statistical data,...
