AB  - Rapid, sensitive and selective method was studied for the determination of 
      glyphosate in rice and wheat flour using a Raptor Polar column. Samples were 
      extracted with acidified methanol solution. Isotope labeled internal standard was 
      added with the extraction solvent to ensure accurate tracking and quantitation. 
      The glyphosate was analyzed by liquid chromatography tandem mass spectrometry 
      using a Raptor Polar column. Method performance was evaluated through a series of 
      parameters that include accuracy, precision, linearity, limit of detection (LOD), 
      limit of quantitation (LOQ) and matrix effect. Mean recoveries for all matrices 
      were within 96-116% at three fortification levels. Precision for replicates was 
      </=19% relative standard deviation (RSD%) for wheat and </=9% RSD% for rice across 
      all fortification levels. Linearity was good for both matrices with a correlation 
      coefficient >0.999 and residual <20% in the concentration range 0.025-1 mg 
      kg(-1). LOD was 0.005 mg kg(-1)for both rice and wheat flour and the LOQ was 
      0.05 mg kg(-1)for both matrices. The matrix effect was also studied. A successful 
      method for the analysis of glyphosate in wheat and rice flour assure that the 
      criteria of acceptability of the maximum residue levels (MRLs) are insured.
