Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. Instead of the standard SN/T 1114-2002 "Test method of import and export fruit diniconazole residues." This standard compared with SN/T 1114-2002, the main technical changes are as follows. --- Scope adds citrus, pear, apple, peach, banana and other fruits; --- Remove SN/T 1114-2002 sample content; --- Purification method consists of activated carbon and alumina neutral SPE modify dispersive SPE; --- Detection method as modified by liquid chromatography liquid chromatography - mass spectrometry/mass spectrometry; --- Lower limit of detection method consists of 0.02mg/kg revised to 0.005mg/kg. Please note that some of the content of this document may involve patents. Release mechanism of the present document does not assume responsibility for the identification of these patents. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard was drafted. People's Republic of China Hunan Exit Inspection and Quarantine. The main drafters of this standard. Yan Hongfei, Fushan Liang, Wang Meiling, Li Yongjun, Dai Hua. This standard replaces the standards previously issued as follows. --- SN/T 1114-2002.
