Advion is the partner of choice for biopharmaceutical, academic/government researchers, and industrial chemists seeking to enhance their chemical synthesis knowledge, workflow and mass spectrometry results. Using our deep scientific and engineering expertise, we develop a broad portfolio of chemist-centric, purpose-built mass spectrometers, nanoelectrospray ionization sources, flow-chemistry synthesis systems and consumables characterized by their reliability, high quality and flexibility.
The Touch Express™ Open Port Sampling Interface (OPSI), developed by Gary Van Berkel and Vilmos Kertesz, of Oak Ridge National Laboratory, paired with the electrospray ion source of the expression Compact Mass Spectrometer incorporates a low volume, open port of continuously swept solvent, flowing directly into the electrospray ion source of the mass spectrometer.
