A heater integrated gas chromatography (GC) column device according to the present invention is capable of precisely and uniformly controlling a temperature by having a high thermal conductivity, and raising and lowering a temperature at a high speed by having a low thermal mass, such that a measuring time is significantly decreased. The GC column is in contact with a bobbin with a homogeneous temperature distribution, and thus a temperature is homogeneously distributed in each GC column. Further, the heater integrated GC column device according to the present invention has the above-described effects and may have a smaller size.

The present invention relates to a matrix-assisted laser desorption ionization mass spectrometry method and, specifically, a mass spectrometry method according to the present invention comprises the steps of: acquiring a mass spectrum of an analyte by performing matrix-assisted laser desorption ionization of the analyte, wherein a detection spectrum, which is the mass spectrum of the analyte, is acquired using each of two or more matrixes different from one another; and removing, from each detection spectrum, a peak of a corresponding matrix to obtain a matrix-removed spectrum, and then acquiring a corrected mass spectrum of the analyte on the basis of a matrix-removed spectrum for each of different matrixes.

A sample plate for MALDI mass spectrometry, according to the present invention, enables separately positioning, by means of a plastic insulation plate, metal wiring and metal dots onto which an analyte sample is to be loaded, and electrically connecting same by means of a via or a metal portion, and thus the energy transferred into the plate when radiating a laser beam on the target (metal dots) may be reduced compared to a sample plate using a base metal, and thus laser energy may be concentrated on the target, and an effect may be achieved whereby heat loss is minimized.
