Enhancement in sample preconcentration by the on-line incorporation of cloud point extraction to flow injection analysis inside the chemiluminescence cell and the determination of total serum bilirubin

Determination of free bilirubin and its binding capacity by HSA using a microfluidic chip‐capillary electrophoresis device with a multi‐segment circular‐ferrofluid‐driven micromixing injection

“…Various methods have been developed for assessing the binding capacity of HSA for bilirubin such as enzymatic assay [8], fluorimetric method [9], chemiluminescence [10], electrochemical sensor [11], fiber-optic sensor estimation [12] as well as chromatographic separation methods such as Sephadex gel filtration method [13], HPLC [14] and CE [15]. However, the existing methods are operating under conditions which can cause disturbance of the equilibrium between free bilirubin and HSA.…”

Spectrofluorometric Determination of Total Bilirubin in Human Serum Samples Using Tetracycline-Eu3+

“…In addition, a modified Jendrassik-Grof method (J-G method) and spectrophotography 3,4 are also familiar methods to determine BR in clinical analysis. Several methods, such as the spectrophotometric method, 5,6 bilirubin oxidase enzymatic analysis, [7][8][9] fiber optic sensor, 10 chemiluminescence combine flow injection analysis [11][12][13] and capillary micellar electrokinetic chromatography 14 have been developed. However, using a fluorescent probe to determine BR has not yet been reported.…”

Determination of cadmium in rice and water by tungsten coil electrothermal vaporization-atomic fluorescence spectrometry and tungsten coil electrothermal atomic absorption spectrometry after cloud point extraction

“…The small volume of the surfactant-rich phase obtained from CPE permits the design of extraction schemes of simplicity, high efficiency, rapidness and environmental friendliness, compared with conventional liquid-liquid extraction using organic solvents [2][3][4]. The application of CPE as sample preparation method has been well-documented in the literature for a variety of instrumental methods, such as flame atomic absorption spectrometry (FAAS) [5,6], inductively coupled plasma optical emission spectrometry (ICP-OES) [7,8], inductively coupled plasma mass spectrometry (ICP-MS) [9,10], gas chromatography (GC) [11], high-performance liquid chromatography (HPLC) [12,13], capillary electrophoresis (CE) [14][15][16], and chemiluminescence (CL) [17]. Apart from analyte preconcentration, CPE can also effectively eliminate the matrix effect encountered in ultrasensitive detection schemes, for example, ICP-MS [18] and graphite furnace atomic absorption spectrometry (GF-AAS) [19,20].…”
