Rapid determination of sodium in milk and milk products by capillary zone electrophoresis.
A capillary zone electrophoresis method for the determination of Na in milk and milk products was developed and compared with an International Organization for Standardization/International Dairy Federation standard method that is based on flame atomic absorption spectrometry. The adoption of a background electrolyte consisting of 10 mM imidazole adjusted to pH 3.75 by the addition of oxalic ac...

متن کاملStacking and Analysis of Melamine in Milk Products with Acetonitrile-Salt Stacking Technique in Capillary Electrophoresis
Melamine was measured in real milk products with capillary electrophoresis (CE) based on acetonitrile-salt stacking (ASS) method. Real milk samples were deproteinized with acetonitrile at a final concentration of 60% (v/v) and then injected hydrodynamically at 50 mBar for 40.0 s. The optimized buffer contains 80.0 mmol/L pH 2.8 phosphates. Melamine could be detected within 20.0 min at +10 kV wi...
متن کاملDetermination of melamine in dairy products, fish feed, and fish by capillary zone electrophoresis with diode array detection.
This paper describes an approach to determine melamine (MEL) in liquid milk, yogurt, whole milk powder, fish feed, and fish at residue levels using capillary zone electrophoresis with diode array detection (CZE-DAD) for the first time. Suspicious samples were extracted with 1% trichloroacetic acid while 1 mL of chloroform was used to precipitate fat in the real samples. After centrifuging and f...
متن کاملDetermination of histamine by capillary zone electrophoresis with amperometric detection.
Capillary zone electrophoresis was employed for the determination of histamine using end-column amperometric detection with a carbon fiber microelectrode, at a constant potential. The optimum conditions of separation and detection were 10 mmol/L phosphate buffer, pH 5.6 for the buffer solution, 15 kV for the separation voltage, and 1.35 V (versus SCE) for the detection potential. The linear ran...
