 You can find an example of a DIA experiment in the following link: https://github.com/bigbio/proteomics-sample-metadata/blob/master/annotated-projects/PXD018830/PXD018830-DIA.sdrf.tsv[DIA example]

+==== Data Independent Acquisition - Scan window limits
+
+Additionally to the general _comment[proteomics data acquisition method]_ column, the SDRF-Proteomics file format allows to capture other properties for the DIA method. The following properties are RECOMMENDED for DIA:
+
+- _comment[scan window lower limit]_
+- _comment[scan window upper limit]_
+
+The scan window lower and upper limits are the m/z range used for the DIA acquisition. The values are expressed in m/z units.
+
+Example:
+
+|===
+|        |  assay name  | comment[scan window lower limit] | comment[scan window upper limit]  | comment[data file]
+|sample 1|  run 1       | 400 m/z  | 1200 m/z | FILE_R1.RAW
+|sample 1|  run 2       | 400 m/z  | 1200 m/z | FILE_R2.RAW
