Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard SN/T 1477-2004 "import and export food paclobutrazol residues in"
This standard compared with SN/T 1477-2004, the main technical changes are as follows.
--- Remove the sampling step;
--- Homemade Florisil column to column commercialization;
--- Modify the lower limit of detection.
