Abstract: A hyperbolic ion trap is provided that includes a glass ring electrode and first and second glass end-cap electrodes. Hyperbolic surfaces of the electrodes are coated with a conductive material. The glass ring electrode and glass end-cap electrodes are formed by conforming glass substrates to a refractory mandrel and establishing hyperbolic surfaces thereon using vacuum and heat. Mass spectrometers including a glass hyperbolic ion trap are also provided as well.
