Analysis of abamectin residues in green tea using QuEChERS method and liquid chromatography-tandem mass spectrometry

The present study estimated the residue levels of abamectin (B 1a ) in green tea leaves and tea infusion. Samples were hydrated with water prior to extraction by using the quick, easy, cheap, effective, rugged, safe method and was analyzed with liquid chromatography-tandem mass spectrometry in posit...

Description
Summary:The present study estimated the residue levels of abamectin (B 1a ) in green tea leaves and tea infusion. Samples were hydrated with water prior to extraction by using the quick, easy, cheap, effective, rugged, safe method and was analyzed with liquid chromatography-tandem mass spectrometry in positive ion mode. The matrix-matched calibration was linear over the concentration range of 0.01–2mg/kg with determination coefficients ( R 2 ) >0.995. Recovery rates at two spiking levels (0.1 and 0.5 mg/kg) ranged between 80.5–99.7% with a relative standard deviation
