The four-borough option, which is preferred by telecommunications carriers, would mean that a separate solution would have to be found for Manhattan by 2014.
The selectivity coefficient K MOX, B pot measured by separate solution method was calculated from the following equation: log K A, B pot = E B - E A / S + 1 - Z A / Z B log a A (1).
They were determined by separate solution method using equation (1) and describe the preference of the sensor for the primary ion (Cu2+) relative to the interfering ions, which in our case were: monovalent (Na+, Li+), divalent (Ni2+, Mn2+, Co2+, Zn2+, Pb2+) and trivalent (Fe3+ and Al3+).
In contrast to classical methods of preparing such compounds by mixing separate solutions of Co II) salts, appropriate amino acids and imidazole [16 18], an original method has been applied, in which cobalt II) and imidazole were introduced in the form of a polymeric, pseudo-tetrahedral, semi-conductive complex [Co imid)2]n.
The potentiometric selectivity coefficients of all solid-state ODAP-selective membrane sensors were evaluated by the separate solutions method according to the IUPAC recommendation [ 26].
Photoelectrically active tin selenide coatings of nanometric thickness were manufactured by electrodeposition from separate solutions of Sn and Se precursors.
The solution of the PAD-AZO films was prepared by blending two separate solutions of Zn and Al bound to polymers.
The calibration model was validated by a separate set of 15 mixture solutions.
Mononuclear cells were isolated from individual samples by Ficoll (Biocoll Separating Solution, Biochrom AG, Berlin Germany) density gradient centrifugation.
Monocytes were isolated by Ficoll (Biocoll Separating Solution, Biochrom, Berlin, Germany) gradient centrifugation and plastic adhesion.
