Notes | Absolute area reproducibility improves for all compounds, and sensitive compound responses improve dramatically because of the lack of contact with the injection port. Nitroglycerin: Absolute Area % RSD = 2.6% • Relative Area % RSD = 1.6% TNT: Absolute Area % RSD = 1.5% • Relative Area % RSD = 1.4% |
