Introduction:
The Automatic FAME Rancimat Oxidation Stability Test Equipment is manufactured in accordance with NB/SH/T 0873-2013 "Determination of Oxidation Stability of Biodiesel and Its Harmonic Fuels. Other applicable standards are as follows:
NB/SH/T 0825, EN14112, EN15751, EN16568, ISO6886, GB/T 21121.
The measurement principle of the Automatic FAME Rancimat Oxidation Stability Test Equipment is that the sample is placed in a constant temperature aluminum heating block, and clean air is passed into the biodiesel sample, and the air flows through the sample into the measuring cell containing the absorption liquid and bubbling. The end of the induction period is accompanied by the production of a secondary reaction product, a volatile organic acid (mainly formic acid), which causes the conductivity in the measuring cell to accelerate. The conductivity of the absorbing liquid is recorded by the computer software, and the induction time is automatically obtained by automatically calculating the conductivity to the second-order differential maximum point of the time-varying curve.
Standards:
• ISO 6886:Animal and vegetable fats and oils -- Determination of oxidative stability (accelerated oxidation test)
• EN 14112-2003 :Fatty Acid Methyl Esters (FAME) - Determination of oxidation stability (accelerated oxidation test)
• EN15751 Automotive fuels - Fatty acid methyl ester (FAME) fuel and blends with diesel fuel - Determination of oxidation stability by accelerated oxidation method.
• EN16568 Automotive fuels - Blends of Fatty acid methyl ester (FAME) with diesel fuel - Determination of oxidation stability by rapidly accelerated oxidation method at 120 Degrees.
Features of Automatic FAME Rancimat Oxidation Stability Test Equipment:
1. The software automatically records the conductivity change curve and determines the induced inflection point by calculating the second derivative of the curve.
2. After the test is over, the results of the induction reaction time together with the test process curve will be stored in the database for the query.
3. In addition to measuring the induced reaction time, the software also allows the evaluation of the so-called settling time, that is the time required for the conductivity to reach a certain value.
4. The software can also re-evaluate each test curve. By setting the evaluation time range, a certain segment of the curve is selected for evaluation, so that some abnormal data segments due to cleaning, samples or other reasons can be avoided.
5. The database can store all test related data, including conductivity curve, induction reaction time, method used, test start and stop time, etc.
6. The test data can be queried by setting the query conditions.
7. The software also has the function of multi-curve comparison and curve analysis.
8. Display mode: curve / number, two modes
9. Temperature and flow calibration can be performed by test software
10. The Automatic FAME Rancimat Oxidation Stability Apparatus has 4 working position,which
11. Each sample is individually controlled and can be set automatically according to requirements.
