Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted. People's Republic of China Guangdong CIQ.
The main drafters of this standard. Weiguo Bin, Cai Xuan, Li Da.
Detection food exports Acid Orange Ⅱ No.
1 Scope
This standard specifies a high performance liquid chromatographic method food exports Acid Orange Ⅱ number.
This standard is applicable to the detection of drinks, wine, chili sauce, fish and braised foods Acid Orange Ⅱ number.
Principle 2
The sample was ethanol - ammonia solution was extracted with an amino anion exchange solid-phase extraction (SPE), reversed-phase high performance liquid chromatography - diode array detection
Chromatographic analysis is performed using external standard.
