Many of the determinations used fall into the realm of microanalysis because of the small amounts of contaminants present in the samples . 因为存在于样品中的沾染物含量很少,所以许多测定方法属于微量分析范畴。

The solution background that resulted from the chemical interference , would be the primary factor that effected the sensitivity . especially in the present microfluidic system , the chemical background which was usually inevitable because of the carrier solution , would be eliminated by means of using air as the carrier flow , thus a great signal noise ratio ( snr ) and a great sensitivity could be obtained 在微量分析和超微量分析里,化学干扰产生的溶液背景是影响灵敏度的主要因素,尤其在微流控系统中,载流溶液的背景不可避免,用空气作载流就可以消除背景而获得高信噪比和高灵敏度。
