Sensitivity, Background, Noise, and Calibration in Atomic ...

the signal is small relative to the background. It is common to express the relationship between signal and background as the “signal-to-background ratio” or S/B. (This is often referred to as “signal-to-noise” or S/N, but background and noise are two distinct characteristics). The above example would have an S/B of 0.1.

Determination of Relative Fluorescence Quantum Yields ...

requires knowledge of the refractive index of the solvent, and the absorbance of both reference and sample. The relative method provides good accuracy for solution phase samples (as it uses the gradients to calculate the ΦF), with the added benefit of not requiring an integrating sphere.8 The fundamental principle of the comparative method is that

The more parallel the ion beam, the higher the resolving power that can be achieved. After the ions have been shaped into a parallel beam, they pass through a pair of slits into the third and last vacuum stage. where the time-of-flight mass analysis takes place.
