Microwave plasma torch (MPT) is a simple and low power-consumption ambient ion source. And the MPT Mass spectra of many metal elements usually exhibit some novel features different from their inductively coupled plasma (ICP) mass spectra, which may be helpful for metal element analysis. Here, we presented the results about the MPT mass spectra of copper and molybdenum elements by a linear ion trap mass spectrometer (LTQ). The generated copper or molybdenum contained ions in plasma were characterized further in collision-induced dissociated (CID) experiments. These researches built a novel, direct and sensitive method for the direct analysis of trace levels of copper and molybdenum in aqueous liquids. Quantitative results showed that the limit of detection (LOD) by using MS(2) procedure was estimated to be 0.265 µg/l (ppb) for copper and 0.497 µg/l for molybdenum. The linear dynamics ranges cover at least 2 orders of magnitude and the analysis of a single aqueous sample can be completed in 5-6 min with a reasonable semi-quantitative sense. Two practical aqueous samples, milk and urine, were also analyzed qualitatively with reasonable recovery rates and RSD. These experimental data demonstrated that the MPT MS is able to turn into a promising and hopeful tool in field analysis of copper and molybdenum ions in water and some aqueous media, and can be applied in many fields, such as environmental controlling, hydrogeology, and water quality inspection. Moreover, MPT MS could also be used as the supplement of ICP-MS for the rapid and in-situ analysis of metal ions. Copyright © 2016 John Wiley & Sons, Ltd.

At present, mass entrepreneurship is a hot topic of the times, and helping poor students to start their own businesses is an important issue of social concern and an important means to promote poverty alleviation among poor students in universities. In recent years, with the promotion of mass entrepreneurship, poor students in colleges and universities have achieved remarkable results in entrepreneurship, but influenced by many factors, they face many difficulties in entrepreneurship, and the capacity building of poor students needs to be strengthened. Based on the perspective of capacity poverty alleviation, in order to help poor students in universities to achieve poverty alleviation, it is necessary to start with entrepreneurial capacity and improve students' entrepreneurial capacity. To this end, based on the cultivation of entrepreneurial capacity of poor students in colleges and universities, this paper studies the support mechanism for entrepreneurial capacity of poor students in colleges and universities from the perspective of capacity poverty alleviation.
