灵敏度

According to the device operating principle and energy equipartition theory of thermodynamics,the mechanical-thermal noise is 9.96×10-9 W/Hz1/2,and the background noise is nearly 3.22×10-11 W/Hz1/2,so that the normalized detectivity is deduced to be 9.03×106 cm·Hz1/2/W.

Hz1/2/W。实验表明，器件的噪声中热机械噪声为主要噪声源，大小主要由浓硼硅薄膜的机械性能和器件结构决定，可以通过增大薄膜厚度，减小薄膜面积，从而增加薄膜的特征频率的方法来减小器件受外界振动的影响，但以降低器件的灵敏度为代价。

Based on the previous literatures, the following major innovation works were carried out in this dissertation:(1) The derivatization reaction conditions of ephedrine and pseudoephedrine with sensitive derivation reagent in aqueous system were studied and two new methods were developed for the assay of them by microemulsion electrokinetic chromatography and micellar electrokinetic chromatography with LIF detection. The sensitivity and analysis times were greatly improved compared with the previous reports;(2) A new method of CZE with indirect LIF detection was developed for the simultaneous determination of six coumarin compounds (esculin, esculetin, isofraxidin, genistein, naringin and sophoricoside) with fluorescein as the probe. The proposed method enlarges the application range of LIF detector, and provides new approach for the analysis of certain compounds difficult to derivatize;(3) Based on the above research, an MEKC with indirect LIF detection method for the simultaneous determination of adenine and guanine in DNA extracts from fungus, maize and soybean was established;(4) A new method for the investigation of the complexes formed between human serum albumin and ampicillin sodium under the simulated physiology conditions using laser light scattering technique was developed.
