| | 全二维GCxGC TOF MS对农药的分析 | | 11-09-19 | | Analysis of pesticides is generally performed by conventional capillary Gas Chromatography (GC) in combination with selective detectors, such as Nitrogen-Phosphorous Detector (NPD) or Electron Capture Detector (ECD). However,despite of its high efficiency, a single GC column cannot always resolve all the
analytes of interest in extremely complex mixtures. In addition, this specific application field requires structural elucidation through MassSpectrometry (MS) to guarantee peak assignment certainty. In this view, Comprehensive Two-dimensional GC (GCxGC) is the most suitable approach to overcome the shortcomings of monodimensional GC. | | | | 快速GC TOF-MS对农药的检测 | | 11-09-14 | | Since human beings are permanently exposed to a large variety of pesticides, discussions among scientists and the public are continuously focused on the real, predicted and perceived risks that pesticides pose to people and the environment. The use of each pesticide poses some levels of risk, so it is not surprising that scientists, the regulated community, government officials and the public need a realistic understanding of the risks associated with pesticide use. | | | | HSS86.50顶空进样器与气相色谱联用检测饮用水中三氯甲... | | 11-02-15 | | 随着人们生活水平的不断提高，饮用水的卫生状况越来越成为人们关注的焦点。国家质检总局最近把饮用纯净水纳入了食品质量安全市场准入管理体系，可见饮用水卫生的重要性。由于纯净水中三氯甲烷、四氯化碳具有脂溶性，能在动物体脂肪中长期积累，对人体的健康危害极大。本方法采用静态顶空气进样气相色谱法测定饮用纯净水中三氯甲烷、四氯化碳。方法操作简便、快速，灵敏度较高，具有较好的准确性和重复性。 | | | | 废水中的孕激素和雌激素的检测方法概要(编号:FMS001CH... | | 09-01-21 | | 废水中的孕激素和雌激素的检测方法概要(编号:FMS001CH) | | |
