  Disclosed is an electronic ID database and detection method for pesticide compounds in edible agro-products based on GC-Q-Orbitrap. The electronic ID database includes a collection of various pesticide compounds electronic ID information and is sorted according to retention time in the electronic ID. The electronic ID contains pesticide compounds information, retention time, mass spectrum, fragment ions information and intelligent matching value. The detection method includes sample pretreatment procedures, setting GC-Q-Orbitrap operating conditions and screening procedures for pesticide residues in samples, wherein setting GC-Q-Orbitrap operating conditions includes setting suitable chromatography and mass spectrometry conditions. In pesticide residue screening procedures, firstly, the retention time is used to find out pesticide compounds in electronic ID database. If there is a match, the corresponding electronic ID information is extracted. Then the intelligent matching value is compared, if it is less than threshold value, the result is recorded and displayed, and the screening is completed.

  本发明公开了一种基于 GC-Q-Orbitrap 的食用农产品中农药化合物电子 ID 数据库和检测方法。电子标识数据库包括各种农药化合物电子标识信息的集合，并根据电子标识中的保留时间进行排序。电子 ID 包含农药化合物信息、保留时间、质谱、碎片离子信息和智能匹配值。检测方法包括样品前处理程序、GC-Q-Orbitrap 操作条件设置和样品中农药残留筛选程序，其中 GC-Q-Orbitrap 操作条件设置包括设置合适的色谱和质谱条件。在农药残留筛选程序中，首先利用保留时间在电子 ID 数据库中查找农药化合物。如果匹配，则提取相应的电子 ID 信息。然后比较智能匹配值，如果小于阈值，则记录并显示结果，完成筛选。

  The invention provides methods and compositions for modulating the sensitivity of cells to cytotoxic compounds and other active agents. In accordance with the invention, compositions are provided comprising combinations of ectophosphatase inhibitors and active agents. Active agents include antibiotics, fungicides, herbicides, insecticides, chemotherapeutic agents, and plant growth regulators. By increasing the efficacy of active agents, the invention allows use of compositions with lowered concentrations of active ingredients.
