Abstract: The present invention provides a gas analyzer that can be miniaturized and detect a wide variety of gases with high sensitivity, and a method of gas analysis. A separation column 16 is configured so as to pass a sample gas together with a carrier gas through the inside thereof. A surface acoustic wave device 17 has a base material 21 with an annularly continuous annular surface formed of at least apart of a spherical surface; a surface acoustic wave generating means 22 capable of generating a surface acoustic wave that propagates along the annular surface; and a plurality of reaction parts 23 provided along the annular surface so as to change a predetermined physical quantity of the surface acoustic wave in response to the components of the sample gas. The surface acoustic wave device 17 is arranged so that the sample gas passing through the separation column 16 is reacted with the reaction parts 23.

Abstract: A work carrier includes a movable clamp unit (15) having resiliently connected first and second sliders (26, 27) mounted on a guide rail (24), a lock lever (37) mounted on the second slider and normally urged in a direction to move a toothed portion (41) into meshing engagement with a rack (25), an operating lever (46) pivotally mounted on the second slider, and a cam mechanism (43, 38, 44, 45) operable in response to pivotal movement of the operating lever in one direction such that the second slider is locked in position against movement relative to the guide rail via meshing engagement between the toothed portion and the rack and, subsequently, the first slider and clamp member carried thereon are forcibly displaced away from the second slider while the second slider remains locked on the guide rail.
