Title: Immediate drop on demand technology (I-DOT) coupled with mass spectrometry via an open port sampling interface

Abstract

Here, the immediate drop on demand technology to a mass spectrometer via the recently introduced open port sampling interface and ESI. A maximum sample analysis throughput of 5 s per sample was demonstrated. Signal reproducibility was 10% or better as demonstrated by the quantitative analysis of propranolol and its stable isotope-labeled internal standard propranolol-d7. The ability of the system to multiply charge and analyze macromolecules was demonstrated using the protein cytochrome c. In conclusion, this immediate drop on demand technology/open port sampling interface/ESI–MS combination allowed for the quantitative analysis of relatively small mass analytes and was used for the identification of macromolecules like proteins.
