Determination of Chloride, Nitrate, Sulfate, Nitrite, Fluoride, and Phosphate by Online Coupled Capillary Isotachophoresis-Capillary Zone Electrophoresis with Conductivity Detection

Incorporation of the fluoride induced SiO bond cleavage and functionalized gold nanoparticle aggregation into one colorimetric probe for highly specific and sensitive detection of fluoride

“…Determination of F − can be carried out using techniques like ion chromatography or capillary zone electrophoresis [7][8][9]. Although most of these methods show high sensitivity, they have seldom been used in field analysis because of their non-portability, strict requirements for laboratory facilities and technical operators.…”

Bioanalytical profile of the l-arginine/nitric oxide pathway and its evaluation by capillary electrophoresis

“…Conductivity-based assays were also optimized in a number of practical works relevant to the analysis of the L-arginine/NO pathway [101,179,[247][248][249][313][314][315][316][317]. The major challenge of CD/CCD in the determination of nitrite and nitrate in biological samples is the high concentration of Cl − .…”

“…To avoid this, several approaches were developed. Kaniansky and colleagues have used CZE/CD with integrated ITP cleanup framework, which allows a reliable detection of nitrite, fluoride, and phosphate in the presence of a molar excess of chloride, nitrate, and sulfate ions in the model mixture [314]. This study suggests that a similar technique could be used to determine macro-and micro-constituents at molar ratios <2×10 4 .…”

Determination of imazalil by on-line coupled capillary isotachophoresis with capillary zone electrophoresis

“…It has been shown [7], [8] that this combination of ITP and ZE is suitable for analysis of trace ionogenic constituents present in a large excess of matrix ions. The CITP{ CZE mode utilizes advantages of both methods.…”
