摘要:
An apparatus includes a light source for producing a beam of light, a coupler for coupling the light into a slider waveguide, a beam expander for expanding the beam of light from the waveguide to produce an expanded beam, a collimator for collimating the expanded beam, and a focusing device for concentrating the collimated beam to a focal point. A method of delivering light to a focal point is also described.
摘要:
An apparatus includes a storage medium, a transducer positioned adjacent to the storage medium and along an axis, and first and second support members connected to the transducer at positions that are spaced apart in the direction of the axis.
摘要:
The invention relates to a process for the production of an [18F]fluorohaloalkane which comprises treatment of a solid support-bound precursor of formula (I): SOLID SUPPORT-LINKER-SO2—O—(CH2)nX (I) wherein n is an integer of from (1) to (7) and X is chloro, bromo or iodo; with 18F− to produce the [18F]fluorohaloalkane of formula (II) 18F—(CH2)n—X (II) wherein n and X are as defined for the compound of formula (I), optionally followed by (i) removal of excess 18F−, for example by ion-exchange chromatography; and/or (ii) removal of organic solvent.
摘要:
The invention provides a process for preparation of a fluorohaloalkane, preferably an [18F]fluorohaloalkane of formula (I) wherein X is halo and n is an integer of from 1 to 6; which comprises: reaction of the corresponding organosilicon compound of formula (II): wherein n is as defined for the compound of formula (I); and R′, R″, and R′″ are independently selected from C1-6 alkyl and C1-6 haloalkyl; and R″ may alternatively be the group: with a compound of formula (III): wherein X is as defined for the compound of formula (I) and Y is halo. Intermediates having use in such processes are also claimed.
