Application

Selected application examples
Bis[4-(1,1,3,3-tetramethylbutyl)phenyl] phosphate calcium salt (hemi-Calcium bis[4-(1,1,3,3-tetramethylbutyl)phenyl] phosphate) was used for the preparation of ion-selective electrode (ISE) membranes, for an experimental study aimed towards designing, constructing and applying electronic tongue (e-tongue) which operates as a virtual instrument and was based on the array of potentiometric sensors employing the Sequential Injection Analysis technique (SIA). It was also used in Raman and UV-vis spectroscopy, used to determine amounts of a bulky lipophilic cationic additive, tridodecylmethylammonium chloride (TDMACl), present in polyaniline (PANI) membranes.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Sensitivity of calcium-selective electrodes heretofore has been limited to calcium concentrations above 10(-8) M in the absence of competing ions. We describe the use of calcium buffers to stabilize the free calcium in the reference electrode. Electrode calibration is linear
