Purpose: Demonstrate enhancements in suppression of chemical noise by a combination of anisotropic supersonic expansion and blocked line of sight. Methods: LC-SRM analyses at nano and high chromatographic flow rates using prototype mass spectrometers equipped with various front end ion optics. Results: Increased sensitivity and robustness at higher gas throughputs.
