【求助】寻求氟虫腈最大残留量

农残检测

  • 最近做“氟虫腈”在食用菌(平菇)上的残留分析,请问哪位兄弟姐妹知道氟虫腈在平菇上的最大残留限量是多少?另外,我想用气相色谱检测,但我们这没有ECD-检测器,请问能用NPD-检测器或者 FPD-检测器吗?如果能的话?那么检测条件又是怎样的呢?我急用,那位好心的兄弟姐妹知道的话,请尽快回复我一下?谢谢了。

    氟虫腈(fipronil)的残留限量可以参考: http://www.m5.ws001.squarestart.ne.jp/foundation/agrdtl.php?a_inq=57000

    Simple method for the determination of trace levels of pesticides in honeybees using matrix solid-phase dispersion and gas chromatography
    Abstract
    A simple multiresidue method for the determination of insecticides in honeybees is described. The developed method is based on the matrix solid-phase dispersion technique. A total number of 12 insecticides (azinfos-methyl, buprofezin, chlorpyriphos, chlorpyriphos-methyl, diazinon, ethion, fenitrothion, fipronil, methidathion, phosalone, pirimicarb, propoxur) used on flowering fields are determined by this method. The method uses Florisil and silica as dispersing agents, alumina and silica as cleanup adsorbents and a low polarity solvent system to elute pesticide residues from the honeybee samples. The insecticides were quantified using capillary gas chromatography with a nitrogen–phosphorus detector. The method has shown good recovery (70–110%) for various levels of spiked samples (0.01–1.0 mg/kg). The relative standard deviations were in the range of 2–8% for all pesticides studied. The limits of detection were in the range of 0.005–0.05 mg/kg. The procedure can be applied for the determination of residues of low-polarity and medium polarity pesticides in honeybee samples.

    我们也是用这个网址查的,是厚生省官方网站链接的。

    谢谢了,非常有用,请问哪位朋友用气相色谱(FPD检测器的,我这边只有FPD检测器)检测过氟虫腈的残留含量,我这几天一直在用气谱测量它的1PPM标样,响应值一直不高,我都急死了。谢谢朋友给予指点。告诉我检测条件应该如何,响应值才能提高。
