Automatic Aniline Point Tester aap-6

• aap-6 automatically determines aniline point for wide range of samples.
  
• The use of special infrared detectors gives the instrument its ability to see through dark / opaque samples such as power generation fuels and marine diesel oils.
  
• The measuring cell can be easily removed and placed on an analytical balance for weighing viscous samples which are solid at ambient temperature.
  
• The measuring cell can be cleaned without disassembling, which makes the cleaning easier and safer.

Due to safety concerns with aniline, ISO has developed a new test method (ISO 21493) where the aniline is replaced with a much safer reagent p-anisaldehyde, and the test is defined as the turbidity point. The method also provides an equation which enables the user to calculate the aniline point equivalent based on the turbidity point. Tanaka and aap-6 were heavily involved in the ILS for developing this method. The aap-6 is now equipped with the ISO 21493 mode where the instrument will run the replicate tests according to the repeatability defined in the ISO method.
