▎ 摘　　要

NOVELTY - The device (100) has a sample stage (160) provided with a supporting frame, an extraction component, a conductive layer, and an extraction layer. The extraction layer is located on a surface of the conductive layers. The extraction layer is formed by molecular imprinting of a graphene oxide composite material. The molecular imprint is obtained by using isopropoxide as a template molecule, and methacrylic acid as a functional monomer aggregate. A high voltage power supply (130) is connected with an extraction component device (140). USE - Separating ionization integrated mass spectrum ionization device for carbamic acid ester compound used in an agriculture, a forestry and an animal husbandry. ADVANTAGE - The separation, ionization integrated type mass ionization device can realize high specificity enrichment separation and ionization ionization and mass spectrometric detection of carbamic acid ester compound, which is suitable for field of carbamate compound, fast, high selectivity mass spectraetry detection, without using chromatographic separation, simple detection process, and fast detection speed. The open ionization technology is the core of open type mass spectrum, without or only needing to perform micro pre-processing, directly ionizing the sample under the atmospheric pressure environment, so as to fast the obtain information of the sample. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: A mass spectrometer; and A method for detecting content of carbamic acid ester compound in a sample to be tested. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the separating ionization integrated mass spectrum ionization device for carbamic acid ester compound. 100Integrated mass spectrum ionization device 110Vertical supporting rod 120Extraction component 130High voltage power supply 140Extraction component device 160Sample stage
