Distillation Gas Chromatograph System - Features

GC Application System

Support for High-Temperature Simulated Distillation GC Analysis

The Shimadzu simulated distillation gas chromatograph analysis system supports analysis of high-boiling-point samples (up to 120 carbon number). Examples of analyses conforming to ASTM standards are introduced below.

Support for Crude Oil Analysis


ASTM D7169

The ASTM D7169 standard applies to crude oil samples with a final boiling point (FBP) exceeding 720 °C. Reference Oil 5010 was analyzed by the external standard method using a short capillary column with a thin film thickness.

  • Using CS2 quenching factors
  • Comparison check against reference oil distillation characteristics standard values



ASTM D5307

The ASTM D5307 standard applies to crude oil with a FBP exceeding 538 °C. A packed column was used for analysis by the internal standard method of samples, including those spiked with (n-C14 to n-C17) internal standards.

  • Display of fractions (mass %) above 538 °C



ASTM D7500

The ASTM D7500 standard applies to samples with an initial boiling point (IBP) exceeding 100 °C and a FBP less than 735 °C. In this example, the sample was analyzed by the total area method using a short capillary column with a thin film thickness. Polywax® 655 and Polywax® 1000 are also used to create the retention time – boiling point curve.

Dedicated Injection Unit Handles High-Boiling-Point Samples

Using an OCI-2030 on-column injection unit with the Nexis GC-2030 Capillary Gas Chromatograph achieves low carryover and provides analysis results with high reproducibility.

Diverse Analysis Functions

The simulated distillation GC analysis software offers comprehensive functions to support the calculation of the physical properties required for process management in oil refinery plants, multisample data comparison required for product quality control, and statistical calculations.

Comprehensive Data Conversion and Customization

The software supports conversions and calculations to acquire information about physical properties from the distillation characteristics. It also supports the following official methods in ASTM, ISO, and DIN standards: estimation of physical distillation (ASTM D86: Normal pressure method; ASTM D1160: low-pressure method; ASTM D2887 Appendix X5: diesel oil and jet fuel conversions), flash point calculations (ASTM D7215), NOACK calculations (DIN 51581-2), MOV calculations (ASTM D6417), Reid vapor pressure calculations, cut point and distillate fraction calculation.

Simple Summary Reports of Complex Data

Daily product data management and comparison studies against past data are essential to maintain a high level of product quality. The software permits access to multiple data through simple operations, data comparison between multiple samples, and statistical calculations.

LabSolutions Simulated Distillation GC Analysis Software

The simulated distillation GC analysis software features functions for operations from calibration to sample analysis. Reporting functions include all calculations required by the simulated distillation gas chromatograph standards. A distillation characteristics curve and reference oil analysis chromatogram can be overlaid in reports, and flexible report generation allows free arrangement and customization of items. In addition, the software provides comprehensive post-run analysis functions, including calculation of physical properties and creation of summary reports for multiple data.

High Data Reliability

The keys to obtaining reliable and reproducible data are daily system accuracy management and a robust system configuration.
Optimized software and hardware are combined to deliver the highest data accuracy.

Comprehensive System Check Functions

The system performance must be comprehensively checked in advance to ensure high-accuracy data when analyzing high-boiling-point samples. It is possible to check whether the system performance specifications prescribed in official methods,such as peak resolution, peak symmetry, and relative sensitivity calculations, are satisfied for standard sample analysis and to check for differences from standard values in reference oil analysis.

Compatible with LabSolutions Network Functions

Data acquired using the Shimadzu simulated distillation gas chromatograph system can be registered to the LabSolutions database, together with data acquired using other instruments.
The highly secure database system permits optimal analysis operations. Configuring a network system with LabSolutions CS permits analysis directions and instrument monitoring and control from a remote PC.


  1. The acquisition controller PC controls the analytical instruments. Analysis directions and re-analysis of data can be performed using a client PC.
  2. It is not necessary to install LabSolutions software on the client PC for terminal service.
