New Features and Improvements in Release 2.1

LCxLC Software Release 2.1 (March 2010) has many new features and improvements. See the LCxLC Software Users' Guide for full documentation.

Mesh Objects

LCxLC Software R2.1 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. LCxLC Software R2.1 provides a suite of tools that can be used to create complex mesh objects in a short amount of time.

Graphic Group

LCxLC Software R2.1 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.


LCxLC Software R2.1 has significant improvements for the Computer Language for Identifying Chemicals (CLIC)™:

Linear Retention Index

LCxLC Software R2.1 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).

New and Improved MS Viewing and Operations

LCxLC Software R2.1 has significant improvements for spectral data analysis.

The MS Viewer now supports:

LCxLC Software R2.1 introduces a Batch Mode for library search with search performance up to ten times faster than Interactive Mode.

Blob Analysis Tools

LCxLC Software R2.1 provides several new blob analysis tools and improvements.

Template Matching

LCxLC Software R2.1 has several improvements for template matching:

New and Improved Reporting

LCxLC Software R2.1 introduces new user controls for customizing summary reports and other reports.

The Blob Set Table allows user control of which columns are included and the order in which the included columns are listed.

The Summary Report now supports:

LCxLC Software R2.1 allows users to define a set of rules to filter blob table with Filter Report.

Image Investigator™

LCxLC Software R2.1 introduces a new interface, Image Investigator™, which allows users to analyze multiple chromatograms interactively. Image Investigator allows users to compare chromatograms, blobs, areas, and blob sets from a set of chromatograms, and examine the statistical characteristics and trends. In later releases, Image Investigator will be enhanced with capabilities for clustering, classification, and fingerprinting. The existing Image Comparison tool, which supports pairwise chromatographic comparisons, also is included in LCxLC Software R2.1.

Qualitative and Quantitative Analysis

LCxLC Software R2.1 has several improvements for qualitative and quantitative analysis.

New and Improved Visualization

In LCxLC Software R2.1, the Image Viewer provides several new visualization features.

New and Improved I/O Support

LCxLC Software R2.1 has new and improved I/O facilities.

Other New and Improved Operations

LCxLC Software R2.1 has many other improvements, including:
