ChromSquare - Features

ChromSquare GC×GC Software for Comprehensive Chromatography Data Analysis

Interaction Functions Allow Confirming Spot Information at a Single Glance

A 2D map, chromatogram view, mass spectrum, and spot information can be displayed in the same window.


  • Modulation time and spectra are used to decide whether a peak belongs to a certain spot.
  • Displays peaks in the corresponding one-dimensional chromatogram using the same color as the spot boundary in the 2D map.
  • Moving the cursor across the 2D map displays the corresponding location on the one-dimensional chromatogram and displays the mass spectrum corresponding to that position.
  • Shows the relationship between the 2D map and spot table highlighted.

Prepare Calibration Curves and Perform Quantitative Analysis Easily

Perform quantitative analysis tasks by simply switching between three panels.

  • Simply switch between the three panels displayed in the same window (Schedule, Chromatogram, and Method) to perform qualitative analysis, prepare calibration curves, or even perform quantitative analysis.
  • Identify spots from multiple sets of data for quantitative analysis using retention times or mass spectra similarity filtering.

Closely Linked to GCMSsolution

In addition to being able to directly import data from GCMSsolution, ChromSquare can also use GCMSsolution mass spectra search technology.


  • Directly import data from GCMSsolution.
  • Search spectra using the GCMSsolution library search engine.
  • In upto 5 libraries can be searched simultaneously including linear retention indices.
  • In addition to the general-purpose NIST libraries available for GCMSsolution, an extensive selection of mass spectral libraries from Shimadzu can be used, such as the Pesticide Library.
  • Mass spectral similarity search function with linear retention index filter (LRI filter) enables you to identify unknown compounds in two-dimensional chromatogram more accurately. The LRI filter narrows down a similarity search result by filtering a range of retention indices, which greatly simplifies the search procedure of unknown compounds.
