Embodiment 1

[0035] Such as figure 1 , figure 2 as well as image 3 As shown, the present invention provides a target plate inactivation device for spotting machine, including a frame 1, a housing 11, a hatch 12, a target groove 2 for installing a target plate, and a cover for covering the target groove 2. Sealing cover 3, gap 31, atomizer 4, No. 1 diaphragm pump 5, No. 2 diaphragm pump 6, exhaust gas treatment bottle 7, air inlet 8, air outlet 9. The casing 11, hatch 12, target slot 2, sealing cover 3, atomizer 4, exhaust gas treatment bottle 7, No. 1 diaphragm pump 5 and No. 2 diaphragm pump 6 are all installed on the frame 1, and the sealing cover 3 and the target slot 2 cooperate to form an inactivation space, and the air inlet 8 and the air outlet 9 are arranged on the wall of the inactivation space.

[0036] The target groove 2 is slightly larger than the target plate, and is used to place the target plate. Meanwhile, a magnet is also arranged in the groove to fix the target plat...

Embodiment 2

[0047] The difference between this embodiment and Embodiment 1 is that only one diaphragm pump is included, and the diaphragm pump is connected with the exhaust gas treatment bottle 7 to provide power and drive the alcohol mist to move into the exhaust gas treatment bottle 7 through the sealing cover gap 31 and the air outlet 9 , because the diaphragm pump discharges the air or alcohol mist in the inactivation space, thereby controlling the airflow direction in the inactivation space, and at the same time, the atomizer 4 continuously generates mist, which will enter the inactivation space and be discharged from the air outlet 9 , can also fully inactivate the target plate. This embodiment can reduce one diaphragm pump and save cost.

Abstract

The invention discloses a sample application machine, a target plate inactivation device and a target plate inactivation method. The target plate inactivation device comprises a machine frame, a target groove used for mounting of a target plate, a sealing cover used for covering the target groove, an atomizer, pumps, a tail gas treatment bottle, an air inlet and an air outlet, wherein the target groove, the sealing cover, the atomizer and the pumps are all mounted on the machine frame, the sealing cover and the target groove cooperate to form an inactivation space, the atomizer is used for providing inactivation fog, the pumps are used for providing power to drive the inactivation fog to move to the inactivation space through the air inlet and then to be discharged through the air outlet,and therefore the purpose of performing microorganism inactivation on a target surface through alcohol fog is achieved. According to the sample application machine, the target plate inactivation device and the target plate inactivation method disclosed by the invention, the inactivation liquid can be atomized by arranging the atomizer to drive the inactivation liquid to inactivate the target plate, a microbial inactivation purpose is achieved, besides, the cross-contamination is avoided, and the detection accuracy is significantly improved.

Description

technical field [0001] The invention relates to sample pretreatment, and more specifically, relates to a spotting machine, a target plate inactivation device and a target plate inactivation method. Background technique [0002] The working principle of MALDI-TOF-MS is to use matrix-assisted laser desorption ionization to analyze the components on the surface of the sample to be tested into ions. After passing through the time-of-flight mass analyzer, ions with different mass-to-charge ratios (m / z) are separated according to the length of flight time. Separated, forming mass spectral peaks (mass spectrum) of different intensities. In the field of microbial identification, it uses standard strains and strains with clear source typing to establish a bacterial or fungal mass spectrum database, and then uses MassLynx software (or other related software) to compare the mass spectrum of unknown strains with the database to determine the identity of the microorganisms to be tested. ...
