Product Information
Ascorbic Acid (AsA) Content Assay Kit
4℃ Wet Ice Transportation
  • 检测样本量:50 Samples
  • 主要检测设备及配套:紫外分光光度计/1 mL 石英比色皿(d=10 mm)
  • 预计测定时间:4 h (50 Samples)
  • 试剂储存条件:按照标签要求储存
  • 需自备试剂:
Detection Principle
抗坏血酸氧化酶(Ascorbate Oxidase)可催化抗坏血酸氧化生成脱氧抗坏血酸,抗坏血酸在265 nm处具有特征吸收峰,通过吸光值变化速率即可定量检测抗坏血酸的含量。
  • 检测方法: AsA比色法
  • 检测波长: 265 nm
  • 信号响应: 递减型
Refreence Information
  • 标准物质: Ascorbic Acid
  • 参考标准: y=0.0009x-0.0012(R2=0.9992)
  • 标准线性范围: 100-1400 µmol/L
  • 检测限: 40 µmol/L
  • 注:不同仪器及比色材质会对结果产生影响,以实际测定值为准。
Notices

①若同时测定多个样本,可根据样本量按试剂一:试剂二 = 8:1的体积比配制为检测工作液(现用现配,严禁一次性全部配制储存使用);1 mL石英比色皿中加入100 µL待测样本(或100 µL标准应用液),再加入900 µL检测工作液,充分混匀并立即开始计时;

②准确在30 s和150 s处完成吸光值测定,以保证实验结果的准确性和重复性;

③若A1测定大于1.4,建议将待测样本使用提取液适当稀释后再进行测定,计算时相应修改;

注: 为保证结果准确且避免试剂损失,测定前请仔细阅读说明书(以实际收到说明书为准),确认试剂储存和准备是否充分,操作步骤是否清楚,且务必取2-3个预期差异交的样本进行预测定,过程中问题请您及时与工作人员联系。
