1昆虫性信息素提取与分析显示文摘详细介绍了昆虫性信息素的常用提取方法,指出了不同方法(有机溶剂浸泡法、冷凝法、动态顶空吸附法、固相微萃取)的优缺点,并探索性信息素化合物的鉴定方法,旨在为有关昆虫微量化合物的研究提供借鉴。马涛 林娜 刘小蓓 张娜 张曼玉 黄夏宁 温秀军 2018实验技术与管理2018,35,12:11
2Chip-based ion chromatography (chip-IC) with a sensitive five-electrode conductivity detector for the simultaneous detection of multiple ions in drinking water显示文摘The emerging need for accurate,efficient,inexpensive,and multiparameter monitoring of water quality has led to interest in the miniaturization of benchtop chromatography systems.This paper reports a chip-based ion chromatography(chip-IC)system in which the microvalves,sample channel,packed column,and conductivity detector are all integrated on a polymethylmethacrylate(PMMA)chip.A laser-based bonding technique was developed to guarantee simultaneous robust sealing between the homogeneous and heterogeneous interfaces.A five-electrode-based conductivity detector was presented to improve the sensitivity for nonsuppressed anion detection.Common anions(F^(−),Cl^(−),NO_(3)^(−),and SO _(4)^(2−))were separated in less than 8 min,and a detection limit(LOD)of 0.6 mg L^(−1) was achieved for SO_(4)^(2−).Tap water was also analyzed using the proposed chip-IC system,and the relative deviations of the quantified concentration were less than 10%when compared with that a commercial IC system.Xiaoping Li Honglong Chang 2020Microsystems & Nanoengineering2020,6,1:2
