The Factors Determining S/N Ratio

Definition of S/N Ratio

Sensitivity is affected by many factors. Some important factors related to hardware and analysis are listed here. It is important to increase signal intensity and decrease noise for high sensitivity analysis.
Some data treatments, such as over-smoothing and a mass chromatogram with an unrealistic narrow mass window, could also improve the S/N ratio, but these are meaningless for practical analysis.
