“…[33][34][35] Recently, ISEs have been often used as a detector of SIA. [36][37][38][39][40][41][42][43] An ideal automated analytical method for the determination of ASs will be developed using a combination of advantages of the SIA system and microfluidic chips with embedded miniaturized ISEs. Generally, AS in environmental water samples is not determined using AS-ISEs because lower limit of Nernstian response of reported AS-ISEs is order of approximately 10…”

A sequential injection analysis (SIA) system with on-line preconcentration technique using a microfluidic chip with an embedded anionic surfactant ion-selective electrode (AS-ISE) as a detector, was developed for the determination of anionic surfactants. Under the SIA system with no on-line preconcentration technique, the AS-ISE in the SIA system showed a linear relationship between peak heights and logarithmic concentrations of AS ion such as dodecylbenzene sulfonate (DBS) ion with a Nernstian slope of 60.4 mV decade −1 in a concentration range from 3.0 × 10 −6 to 1.0 × 10 −3 mol dm. For the determination of trace levels of ASs, on-line preconcentration technique with solid-phase extraction process was incorporated into the SIA system. By using the on-line preconcentration technique in the SIA system, DBS ion in a concentration range from 1.0 × 10 −7 to 3.0 × 10 −6 mol dm −3 was successfully determined. The recovery for DBS ion added to river water samples was ca. 91-97% using on-line preconcentration technique in the SIA system. The result shows that the present SIA system with the on-line preconcentration technique can be applicable to the determination of the level of AS ion in river and tap water samples.

“…Low levels of EP have been found in patients with Parkinson's disease [20][21][22]. From the point of view of medicine, it is a drug for emergency treatment in severe allergic reaction, cardiac arrest and sepsis [23]. Therefore, the quantitative determination of EP concentration in different human fluids, such as plasma and urine, is important for developing nerve physiology, pharmacological research and life science [24].…”

“…And the development of sequential injection lab-on-valve (SI-LOV) format provides vast potentials for instrumental miniaturization and automatization and online detection [ 22 – 25 ]. The volumes and dimensions of fluidics are downscaled in a “digital” fashion by stopping, reversing, and accelerating flow rates, with the aim of making this technique compatible with advances in instrument miniaturization [ 26 – 28 ]. The present work adds a novel facet to the LOV technology for the determination of morin by implementing amperometric measurement.…”

The potential capabilities and analytical performance of lab-on-valve (LOV) manifold as a front end to amperometry have been explored for the on-line determination of morin. Meanwhile, the electrochemical behaviors of morin were investigated based on polyvinylpyrrolidone- (PVP-) doped carbon paste electrode (CPE), which found that PVP can significantly improve its oxidation peak current. The excellent amperometric current response was achieved when the potential difference (ΔE) of 0.6 V was implemented in pH 6.5 phosphate buffer solution (PBS) that served as the supporting electrolyte. A well-defined oxidation peak has been obtained in studies using PVP as a modifier of CPE based on the oxidation of morin. The present work introduces the LOV technique as a useful tool for amperometric measurement, documents advantages of using programmable flow, and outlines means for miniaturization of assays on the basis of PVP modified CPE. The proposed method was applied successfully to the determination of morin in real samples, and the spiked recoveries were satisfactory.
