Abstract: PURPOSE:To facilitate the attachment and the removal of a sample chamber and to facilitate the removal and the placement of a sample out of an into the sample chamber and the arbitrary positioning of the sample by making it possible to slide the lower half part of the sample chamber, and providing an external operating member for moving the sample up and down at the bottom part of the sample chamber. CONSTITUTION:A sample chamber 5 is divided and fixed to a base 6. The sample chamber (low) 10 is constituted so that the chamber can be moved on a sliding plate 9 located on the upper surface of the base 6. A rotary shaft 13 and a knob 14 are provided at the sample chamber (low) 10, and the position of the sample 4 can be arbitrarily changed. The sample chamber (low) 10 can be readily moved. The sample chamber (low) 10 is smoothly moved toward an operator by pulling out the knob 14 through the sliding plate 9 on the upper surface of the base 6. Then, the sample 4 in the sample chamber (low) 10 is moved up and down by the rotation of the rotary shaft 13 having the screw structure. Therefore, when the rotary shaft 13 is operated and the shaft is made to extend from the upper surface of the sample chamber (low) 10, the chamber can be readily replaced. In this way, the replacing work of the sample chamber can be readily performed, and the attachment and removal of the sample into and out of the sample chamber and the arbitrary positioning of the sample can be performed.

Abstract: PROBLEM TO BE SOLVED: To maintain a positional relationship constant even when a force is applied to a torch by setting a torch branch pipe clip which enables a torch branch pipe to be fitted by rotating the torch centering a center axis of the torch. SOLUTION: The inductively coupled plasma emission spectrochemical analyzing apparatus is provided with a torch branch pipe clip 9 for holding, e.g. a plasma gas feed pipe 10 of a torch 12. A gap of the torch branch pipe clip 9 has an equal size to an outer diameter of the plasma gas feed pipe 10. The plasma gas feed branch pipe 10 is fitted by rotating the torch 12 about a center axis of the torch after setting the torch to a torch-fixing tool 7. The fixed torch 12 is accordingly prevented from moving back and forth in a direction of the center axis. A positional relationship in the direction of the center axis between an XYZ stage 14 and the torch 12 is kept constant. Unless a position of the XYZ stage 14 changes, a positional relationship between a plasma 2 formed to a leading end of the torch 12 and a sampling cone 1 or the like is constant at all times, and therefore measurement results of good reproducibility can be obtained.
