Mass Spec Sampling Device

Explore the design concept of an advanced mass spectrometer sampling device featuring auto-sampler with specified features, CO2 intake and flushing system, and in-line safety bottle. The design includes Cartesian robot with Z actuation, fixed tray of samples, and septa bottle tops for efficient sample handling. Discussion covers sample cataloging, software integration, electrical control system, and CO2 injection and flushing system.
