【摘要】 本文采用气相色谱法测定奶粉中的ＥＰＡ和ＤＨＡ。ＦＩＤ检测定量。本方法的最低检测线：ＥＰＡ为２．０×１０－９ｇ；ＤＨＡ为５．０×１０－９ｇ。变异系数：ＥＰＡ为ＣＶ％＝２．３７；ＤＨＡ为ＣＶ％＝２．６２。平均回收率：ＥＰＡ为９７．８４％；ＤＨＡ为９７．９１％。更多还原

【Abstract】 This is a method for determination of EPA and DHA in milk powder by GC The detector FID was applied for quantity analysis.The minimum detectable value of EPA is 2 0×10 -9 g and DHA is 5 0×10 -9 g The variation coefficient (CV%) of EPA is 2 37 and DHA (CV%) 2 62 The recovery of EPA is 97 84% and DHA is 97 91 per cent更多还原
