Embodiment Construction

[0064] The present invention will be described in further detail below in conjunction with the accompanying drawings and examples. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0065] A sample pointing instrument includes a frame, a sample pointing device, an inactivation device, a dry storage device, a reagent storage device and a needle washing device.

[0066] Such as figure 1 As shown, the frame includes a shell 11 and a container installation base plate 14, and the shell 11 is movably connected with a hatch 12. In this embodiment, the hatch 12 is rotatably connected with the shell 11, and the shell 11 encloses the space inside the machine. The casing 11 encloses an operating space, and the hatch 12 is provided with an observation window 13 for observing the state in the operating space. The upper surface of the casing 11 is recessed downward to form a mounting portion 14 for container instal...

Abstract

The invention discloses a spotting instrument which comprises a rack, a spotting device, a drying and storing device, a reagent storing device and a liquid path device, and the spotting device, the drying and storing device, the reagent storing device and the liquid path device are all arranged on the rack; the sample application device comprises a target plate platform used for mounting a targetplate, a sample application needle used for sample application and a driving device used for driving the target plate platform or the sample application needle; the drying and storing device is arranged on the motion trail of the target plate platform so as to dry the target plate; and the reagent storage device is arranged on the motion trail of the sample application needle. By arranging three-axis linkage movement of the XYZ-axis movement assembly, full-automatic accurate sample application of the sample injector to the target plate is achieved, and the working efficiency is greatly improved. By arranging the disinfection bin, the alcohol spray needle is used for disinfecting the target plate, the effect of inactivating microorganisms is achieved, pollution is reduced to the maximum extent, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to sample pretreatment, in particular to a spotting instrument. 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. species. Compared with other microbial detection techniques, MALDI-TOF-MS technology is...
