Abstract
Apparatuses and methods for removing caps, such as NMR rotor caps. The apparatuses and methods may permit caps to be removed in a manner that minimizes damage to equipment and instruments. Microwave waveguides that may include an elongated waveguide, a spline horn, and a slotted waveguide. Analytical instruments that include the waveguides.
Claims15
A slotted waveguide comprising:
- a metallic tube having a first end and a second end;
- and
- a sample tube inserted partially into the second end of the metallic tube;
- wherein the metallic tube defines a plurality of slots in a surface of the metallic tube, wherein each slot of the plurality of slots consists of a linear slit having a length, a width, and a thickness, wherein the length exceeds the width, the length exceeds the thickness, and every length of the plurality of slots is oriented perpendicularly to a longitudinal axis of the metallic tube, and wherein the first end of the metallic tube is configured to be coupled to a device for directing or controlling electromagnetic radiation, and wherein the metallic tube is not corrugated.
