UniChrom-SIMDIS

The UniChrom-SIMDIS system is intended for realisation of calculative methods regulated by
ASTM D 2887 "Standard Test Method for Boiling Range Distribution of Petroleum Fractions by Gas Chromatography" -

UniChrom-SIMDIS system consists itself from two components:

• SIMDIS-capable gas chromatograph
• UniChrom-SIMDIS calculation software package.

Chromatographic System

Chromatographic data can be obtained directly from GC under UniChrom control or loaded from data files, which format is supported by UniChrom.

UniChrom-SIMDIS service

UniChrom-SIMDIS is yet another extension to UniChrom system (like UniChrom-DHA etc).
The service is intended for calculation simulated distillation curve of petrol fractions and crude oil using chromatographic data.

	UniChrom-SIMDIS service just started from "Service Manger" window shows currently selected sample. The information on where to get calibration, blanc and actual distillation is got from method properties. Due to nature of UniChrom Workbooks, all the chromatograms are stored in single file and can be viewed simultaneously , separately or selectively.
	UniChrom-SIMDIS gains the access to all chromatograms and can not only calculate them but display it in scalable manner. At the picture - calibration with normal paraffins mixture.
	The blanc chromatogram on the background of calibration chromatogram.
	The integral chromatogram on the calibration background.
	Boiling temperature as the function of retention time T=f(t)
	The distillation curve. The dependence of boiling temperature from distillated percents.
	Obtaining ASTM D86 data through the mathematical correlations Different correlations shown on the background of distillation curve. API - American Petroleum Institute correlation STP 577 - special technical publication #577
