Abstract
Chlormequat is a plant growth regulator widely used on cereals, and there is general concern that it may impair human fertility. A LC–MS/MS method for the analysis of chlormequat in milk and serum was developed and validated in connection with an investigation on the effect of chlormequat on pig reproduction. Validation of the method was based on recovery tests at three spiking levels, determined as double determinations and repeated at least four times. Samples were extracted with methanol–water–acetic acid, centrifuged, filtrated and determined by LC–MS/MS. The mean recoveries were in the range 80–110%, and the LOD was 0.2 ng/g for serum and 0.3 ng/g for milk. The values for repeatability and reproducibility were within 2/3 of the limits given by the Horwitz equation. Samples of pig serum (59) and sow milk (27) were analyzed using the method. Chlormequat was determined in four milk samples in the range of 0.4 ng/g to 1.2 ng/g and in all serum samples in the range of 0.2 ng/g−4.0 ng/g.

Determination of chlormequat in pears by high-performance thin layer chromatography and high-performance liquid chromatography with conductimetric detection

Abstract
The purpose of this paper is to present two simplified methods which involve inexpensive equipment and which can be applied by all analyst who have to determine chlormequat residues in pears. The two methods use the extraction with methanol and purification by formation of ion-pair with sodium tetraphenylborate. A first method is a high-performance thin layer chromatography (HPTLC), the second is high-performance liquid chromatography (HPLC) with conductimetric detector. The results obtained for the same samples by the two methods are quite comparable. These two methods are rapid and particularly the thin-layer chromatography.

我刚制定好粮食中矮壮素残留测定国家标准方法 GCMS法,原理与日本的方法一样,方法已经通过审定,不过LC/MS测定应该是最方便的,但使用有局限性.方法我的同事已经发表了论文,可以查到.

大侠，能否把论文的题目说一下？找了一下好像没有。
