Purpose: Demonstrate the performance of the Thermo Scientific Orbitrap Ascend Tribrid mass spectrometer (MS) and Thermo Scientific Vanquish Neo UHPLC system in the analysis of low input and single cell samples.

Methods: A label-free DIA-based method that gives a throughput of 50 samples per day (SPD) is demonstrated with low input samples (HeLa peptides) and single cell samples. Results: Our results show that the Orbitrap Ascend Tribrid MS coupled to Vanquish Neo UHPLC has single cell sensitivity.
