Calibration essential performance characteristic

The method s standard deviation (DIN 32645, DIN 38402 T51) represents the key parameter of performance. It is calculated by dividing the residual standard deviation by the sensitivity of the method and it essentially determines the maximum precision for evaluation of analytical results. The standard deviation of a method provides the scale to estimate the accuracy of a method early on the basis of its calibration characteristics. 

Additional extensive test series to complete one s own calibration characteristics will provide no further essential information to assist in correctly choosing the better method. This effort is only suitable for validation purposes, in order to provide the most realistic information about the performance of the method of one s choice to be established in a routine application. 

Constant pressure simulations of tiidecane confined between atomistic, weakly attractive parallel plates using a calibrated EA force field have been performed for films of nominal 4 nm thickness as 450 The most interesting difference between these and earlier UA simulations is the extension of ordering effects near the surfaces farther into the bulk, similar to the effects seen in the previous constant volume EA simulations (see Fig. 8.17). The monomer density profile and order parameter for the constant pressure EA simulations at 450 K are very close to those for the constant volume EA simulations. The apparent diffusivity perpendicular to the surfaces shows the characteristic decrease as one approaches the surfaces, while the overall mobility is essentially unaffected. This is consistent with previous results obtained for surfaces which are not strongly attractive. The bulk value of the diffusion constant of 3.3 x 10 cm /s, obtained from the diffusivity at the center of the 4nm film, agrees reasonably well with the experimental value of 5.0 x 10 cm /s. This is in contrast to some UA...
