Disclosed are an improved guide device capable of being easily replaced for damage, and a detector having the same. The guide device includes a first plate configured to have a plurality of grooves disposed in one surface thereof; and a second plate configured to be in contact with the first plate, wherein the second plate is in contact with the first plate to separate a plurality of channels, wherein the first plate is configured so that the plurality of microdroplets pass through any one of the plurality of channels, the fluid passes through channels facing each other among the plurality of flow channels, and the microdroplets are regularly spaced apart by the fluid that is discharged from the channels facing each other.

Guide apparatus and detector having the same

An electrode assembly, in which a positive electrode, a separator, and a negative electrode are repeatedly stacked includes a shrinkage film made of a material having a thermal shrinkage rate greater than that of the separator, the shrinkage film being shrunk in area at a specific temperature or more, wherein the shrinkage film is disposed instead of the separator at one or more positions between the positive electrode and the negative electrode so that, when the shrinkage film is shrunk by an increase of a temperature, the positive electrode and the negative electrode, which are adjacent to each other with the shrinkage film therebetween, partially contact each other to generate microcurrent.

Electrode assembly

The present invention relates to an extinguishing composition and comprises an extinguishing material and a capsule containing the extinguishing material, and the extinguishing material comprises calcium bromide (CaBr2).
