Block correction methods

In addition to these parameters of line-by-line solvers, several other techniques have been proposed to accelerate the convergence rate. Some of these methods are discussed in Section 6.2.2 and only brief comments will be added here. One-dimensional block corrections based on an additive correction philosophy (Kelkar and Patankar,... 

It can easily be shown that an experimentally generated curve coincides with the synthetically generated DGS curve having applicable corrections (transfer loss and sound attenuation) with acceptable tolerances. However, our intention is not to replace the reference block method by the DGS method. In practical application you may encounter many cases, where only the reference block method can be applied, e.g. ... 

These methods model the log P by adding the specific contributions of elementary building blocks of a molecule, that is, the chemical monoatomic or multiatomic fragments. The geometrical and topological effects that operate in such a case mean that several correction factors have to be added to the additivity scheme. 

ETAAS was also combined with PLS by Baxter et al. [76] to determine As in marine sediments. They demonstrated that the classical standard additions method does not correct for spectral interferences (their main problem) because of mutual interactions between the two analytes of interest (As and Al). PLS-2 block was applied to quantify simultaneously both elements (PLS-2 block is the notation for the PLS regression when several analytes are predicted simultaneously it is not widely applied, except when the analytes are...
