The qld file extension is associated with MassLynx, a mass spectrometry data system developed by Waters for Microsoft Windows.
A qld file stores quantitation data generated by MassLynx for quantitative analysis and is intended to be handled by that software rather than as a general-purpose data file.
Open a qld file in MassLynx on Microsoft Windows. The file may depend on other data in the associated MassLynx project, so keep it with the related project files and open it from within MassLynx.
Use MassLynx to review the quantitation data and generate an export or report in a format supported by that software.
