This document introduces the characteristics of the Agilent 1100 Series LC/MSD electrospray interface, including system composition, working principle, application range, etc.
The document investigates how nonvolatile buffers, specifically potassium phosphate at different pH levels, affect the performance of the Agilent 1100 Series LC/MSD. It compares signal response and spectral integrity against volatile ammonium acetate buffers using test compounds like theobromine, theophylline, and caffeine.
The study analyzed theobromine, theophylline, and caffeine.
The system operates with a flow rate of 0.2 ml/min.
The test compounds in phosphate buffer were injected 100 times over 16 hours.
