This depends upon what you are sorting for. Here is what we do at our site.
If the sort is for cells that will be grown in culture we tend to
threshold high to eliminate counting of debris. This increases our
sort throughput, and generally the randomly sorted debris doesn't
If the sort is for DNA/RNA/protein analysis, we generally threshold
low to exclude debris, since randomly sorted debris could be a
contaminating artefact to the subsequent measurements.
