Abstract: 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.

Abstract: An ion guide for transferring ions to a mass analyzer is disclosed. The ion guide is characterized in that a plurality of DC rings and a plurality of RF multi-pole rings with a plurality of electrodes are arranged alternatingly along a central axis between an inlet into which the ions move and an outlet for transferring the ions. The inner diameter of the DC rings is kept constant and the inner diameter of the RF multi-pole rings gradually decreases in a direction from the inlet to the outlet.

Abstract: A sample concentrator tube having a heat-resistant planar heating element adhered thereto, an analysis device comprising the same, and an analysis method using the same, according to the present invention, have an effect capable of precisely controlling the temperature by uniformly and rapidly heating the sample concentrator tube to a target temperature for desorption, and capable of almost simultaneously desorbing an adsorbed sample in any part of an adsorbent by minimizing a local temperature difference of the adsorbent in the tube. In addition, it is possible to minimize chemical noise by preventing thermal denaturation of the adsorbent caused by over-heating, and there is an advantage of excellent reproducibility as well as an effect of being inexpensive, economical, and excellent in energy efficiency.

Abstract: 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.
