Sensitivity ratio

Consequently, knowledge of the t90 of both coils - for the same applied rf power -allows a rough calculation of the expected signal-to-noise ratio, in agreement with the principle of reciprocity [27]. The sensitivity ratio between the two coils is thus given by... 

On line additions of aqueous standard solutions for the calibration of LA-ICP-MS including a comparison of wet and dry plasma conditions are discussed by O Connor et al.ls For solution calibration of standard solutions the authors used a 100 (xl PFA nebulizer together with a cyclonic spray chamber or a MCN-6000 sample introduction system with desolvator, to study the wet and dry plasma, respectively. A polypropylene Y piece was applied to mix the laser ablated material and the nebulized standard solutions. The authors found that the on line addition of water is the preferred mode of operation for quantification by LA-ICP-MS, i.e., wet plasma is more stable (improved standard deviation of sensitivity ratios).

The C, H and O-containing polymers studied, with the theoretical 0 C ratios derived from the formula of the repeating chemical unit. Also listed are the measured 0 C ratios obtained by comparing the ISS peak, 2750eV He+) and the ratios after correction for the difference in sensitivities of the two elements based on the sensitivity ratio 0 C = 18.1 1. 

The two dimensionless parameters a and p appear to be especially helpful. a is the ratio of the radius of gyration of any intermediate along the approach to the phase boundary and the radius of gyration of the unperturbed chains, i.e., the 0-state (see Eq. (4). The latter were determined experimentally in 1.5 M NaCl. The second parameter is the shape sensitive ratio p of the radius of gyration and the hydrodynamic radius (see Eq. (17). 

The method of defining RSFs described is traditional in analytical chemistry, generates RSFs without units, results in larger numbers for elements for which the SIMS instrument is more sensitive, and is essentially the same as Wittmaack s proposed use of scaled sensitivity ratios [100]. However, an alternative definition of sensitivity factors that has gained much popularity with semiconductor specialists is that of Wilson [69,101] ... 

DADPyOx. (HMX/TNT is a critical case It exhibits an interesting performance/sensitivity ratio when only two tests are taken into account). The IHE TATB and DADPyOx accomplish an important precondition as they possess the best structure for an energetic molecule Cyclic, aromatic, highly nitrated, a stabihzing effect from the intramolecular hydrogen bonding between the nitro and the adjacent amino groups. 

The following tables report the sensitivity ratio (S.R.) of the indicator in water and in alcohol. A ratio less than 1 signifies that the indicator is more sensitive to alkali or acid in alcohol than in water and when the ratio exceeds unity, the indicator is less sensitive than in water. It would be desirable to repeat these experiments in buffer mixtures. These data are only approximate because of the difficulties involved. 

The significance of these data is brought out more clearly by plotting sensitivity ratios versus alcohol content (Figs. 10, 11, 12, p. 212). We observe the following ... 

The curves are uniform and contain no discontinuities. As the alcohol content increases, the sensitivity ratio may grow smaller or larger continually as in the case of phenolphthalein, or it may approach a maximum or minimum constant value at a certain alcohol concentration. Nitramine, thymol blue (in acid or alkaline solution), and curcumin behave in the latter fashion.
