New Features and Improvements in Release 2.0

GC Image Release 2.0 (March 2009) has many new features and improvements. See the GC Image Users' Guide for full documentation.

Mesh Objects

GC Image R2.0 introduces mesh objects for comprehensive group analysis. A mesh object is a collection of panels that supports shared edges and vertices. Chemically similar compounds often form a cluster of peaks. A panel of a mesh can be drawn to include the peaks of desired compounds and exclude the peaks of other compounds. The mesh allows a set of panes that can be used for comprehensive analysis, i.e., covering all of the relevant regions of the chromatogram. GC Image R2.0 provides a suite of tools that can be used to create complex mesh objects in a short amount of time.

Graphic Group

GC Image R2.0 allows users to define graphic groups. A graphic group allows reporting of summed blob set features for a set of graphics. Each graphic group is comprised of a set of graphics with the same group name that are either areas or included graphics.


GC Image R2.0 has significant improvements for the Computer Language for Identifying Chemicals (CLIC)™:

Linear Retention Index

GC Image R2.0 allows users to define one linear retention index calibration table for each column and automatically computes the linear retention index for all analytes (blobs and area objects).


GC Image R2.0 has significant improvements for quantitative analysis:

Blob Analysis Tools

GC Image R2.0 provides several new blob analysis tools and improvements.

Template Matching

GC Image R2.0 has several improvements for template matching:

Filter Report

GC Image R2.0 allows users to define a set of rules to filter blob table with Filter Report.

Multi-Run Comparison Report

GC Project R2.0 allows users to compare blobs, areas and blob sets from multiple images and examine the changing trends with Multi-Run Comparison Report.

New and Improved I/O Support

New and Improved Operations

The people of GC Image welcome your suggestions of new features, your comments about existing features and documentation, and reports of any problems. We strive to make GC Image meet the needs of our users in their many GCxGC applications.
