A safe reliable solution to aniline point testing with additional capability to measure according to ISO 21493 Turbidity Point Mode

Aniline point is a test method used to ascertain the aromatic content of hydrocarbon samples. Highly aromatic samples display a low aniline point, whereas paraffinic samples have far higher aniline points.  

Tanaka Scientific’s aap-6 is an automatic aniline point tester which can handle a host of different samples in accordance with ASTM D611 and ISO 2977. The aap-6 will run the 3 to 5 replicates, whilst monitoring to ensure the repeatability of the results. This analyser features an accurate and resilient infrared detector to enable accuracy with darker coloured samples.  ASTM 8.0 colour samples can be reliably analysed by the aap-6 and it has regularly managed to test even darker samples. Cleaning the measuring cell can be carried out without the need for any dismantling, so aap-6 operators will find that cleaning the instrument is far simpler and safer than they will have experienced using other aniline point testers. 

ISO recently created test method ISO 21493 because of the safety issues associated with aniline point testing in which aniline is substituted by p-anisaldehyde, which is a far safer reagent. This test method is called the ‘turbidity point’ and Tanaka played an active role in this method’s development. Tanaka’s aap-6 includes an ISO 21493 mode, where the instrument will replicate tests in line with the repeatability stipulated by the ISO’s method.
