In the Near-infrared (NIR) spectral measurement it is not always possible to keep the experimental conditions constant. The fluctuations in external variables, such as temperature, will result in a nonlinear shift and a broadening of the spectral bands. In this study, the temperature-induced spectral variation coefficient (TSVC) was obtained by using loading space standardization (LSS). The relationship...
In this work, chloride, chlorate and perchlorate are fast separated on PDMS microchip and detected via in-channel indirect amperometric detection mode. With PDMS/PDMS microchip treated by oxygen plasma, anions chloride (Cl − ), chlorate (ClO 3− ), and perchlorate (ClO 4− ) are separated within 35s. Some parameters including buffer salt concentration, buffer pH, separation...
In-channel indirect amperometric detection mode for microchip capillary electrophoresis with positive separation electric field is successfully applied to some heavy metal ions. The influences of separation voltage, detection potential, the concentration and pH value of running buffer on the response of the detector have been investigated. An optimized condition of 1200V separation voltage, −0.1V...
Based on resonance scattering (RS) effect of rhodamine dye association particles, a new resonance scattering method for the determination of hydroxyl free radical from Fenton reaction was developed. In HCl–NaAc buffer solution, the OH of Fenton reaction oxidized the excess I − to I 3− . The I 3− combined, respectively, with rhodamine B (RhB), butyl rhodamine B (b-RhB),...
In Na 2 HPO 4 –citric acid buffer solution, Cl 2 can oxidize I − to form I 2 and then it reacts with excess I − to form I 3− . The I 3− combines respectively with rhodamine dyes, including rhodamine B (RhB), butyl rhodamine B (b-RhB), rhodamine 6G (RhG) and rhodamine S (RhS), to form association particles which give stronger...
