New Standard ASTM D7344 for Small Scale Distillation Testing
Jan 14 2008 Read 2754 Times
ASTM D7344 has several advantages compared to the "classical" distillation standard D86. Firstly Small sample volume, - meaning reduced waste; ASTM D7344 works with a sample volume of 6 mL. Compared to D86 this reduces sample volume 15-fold. Therefore waste material is reduced significantly, too.
The MINIDIS performs fast measurement; due to the small sample volume the distillation takes just half the time. Whereas distillation according to the D86 principle takes 40 minutes, the new standard allows distillation times of 15 minutes or less. The MINDIS is ‘safe apparatus’ - The D7344 principle works with small sealed cups and a metallic distillation column. An apparatus built following the D7344 principle needs no fire detection system, like common D 86 instruments: Non-breakable copper cups replace the fragile D86-glassware. Finally, the MINDIS is easy to use; The fully automatic principle makes manual sample handling dispensable. Rinsing, filling, sample lifting and sample introduction are fully automatic.
