321
series of oxidation stability baths conform to the requirements of EN-14122 test
method, soon to be incorporated in ASTM D6751 specifications for B100 fatty acid
methyl esters (FAME) for biodiesel blending. Models 321 series employ multiple aluminum
blocks configured to fit the specified test tube holding 3.0 gm of FAME (fatty
acid methyl esters). When the sample reaches test temperature of 110°C
filtered, dry air is sparged at 10 ± 1L/hr. to each test specimen. The volatiles generated (organic acids) from
this oxidation process are collected in a receiver of distilled or deionized
water. The increase of acidity in the receiver is measured with time with an
integral conductivity measuring device. The oxidation induction period is
automatically calculated based on the break in the rate of increase (second
derivative) of conductivity in the receiver. Each position’s receiver has cap with an
integral conductivity probe reporting data to the PC. (Click on Photo To Enlarge) Other Instruments Available From LawlerClick on links for catalog information. |
