ASTM D1655-MicroDist
Surpassing Expectations With a Real Distillation
State-of-the-Art Solution
For refining and midstream facilities who need the confidence of a reliable, real distillation, MicroDist is a process distillation analyzer capable of delivering boiling point, density, and cetane index in a single measurement.
Product Overview
ASTM D86, ASTM D7345, ISO 3405, D4814, D975, D1655, D7566
The PAC MicroDist online analyzer is designed to quickly and accurately determine the boiling range characteristics of various commercially available petroleum products, light and middle distillates, on process streams.
The easy-to-use MicroDist performs a complete distillation of the sample in less than 10 minutes. The results obtained correlate to the ASTM D86, ASTM D7345, ISO 3405 test methods and their analogs. Due to the fast and reliable measurements, the MicroDist enables precise and continuous adjustment of the process streams. An optional density meter enables continuous Cetane Index analysis.
The analytical engine described by ASTM D7345 is used in MicroDist and our OptiPMD laboratory analyzer, and is an approved method for D4814, D975, D1655 and D7566 fuel specifications.
