      polyamide adsorption-high performance capillary electrophoresis with internal 
      standard method].

AB  - A high performance capillary electrophoresis (HPCE) method has been established 
      for the separation of Brilliant Blue and Amaranth in carbonated beverages. Sunset 
      Yellow was added into the sample as the internal standard. The separation was 
      carried out on a fused-silica uncoated capillary column (40 cm x 75 microm). The 
      sample was injected by air pressure injection (14 kPa x 3 s) at room temperature. 
      The analysis was completed in 10 mmol/L Na2HPO4 buffer (pH 8.56) at 20 kV of 
      separation voltage and 390 nm of detection wavelength. The relative correction 
      factors of Brilliant Blue and Amaranth were 0.8329 and 1.2253, and the relative 
      standard deviations (RSDs) were 3.3% and 2.6%, respectively. The respective 
      quantification limits (S/N = 10) were 1.629 mg/L and 4.160 mg/L, the recoveries 
      were in the ranges of 97.87%-102.1% (RSD = 1.8%) and 94.07%-103.8% (RSD = 4.1%), 
      and the method precisions were 3.2% and 2.0%. The optimization of the 
      pretreatment made the method more suitable for the determination of Brilliant 
      Blue and Amaranth in carbonated beverages by capillary electrophoresis. The 
      systematic error brought by the background was eliminated basically by using the 
      blank sample as the base solution. The relative factors of Brilliant Blue and 
      Amaranth were reproducible in the ranges of 1.629-228.8 mg/L and 4.16-401.6 mg/L, 
      respectively. So this method can be used to quantify the two synthetic pigments 
      in carbonated beverages accurately.
