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.
