Abstract: A nebuliser outlet assembly comprises an inlet end and an outlet end, and a first channel (24) arranged between the inlet end and the outlet end, wherein the first channel is configured to receive a capillary. The nebuliser outlet assembly comprises a first part (40) and one or more second parts (50), wherein the one or more second parts are removably attachable to the first part. The nebuliser outlet assembly is configured such that the first channel is formed from the first part and the one or more second parts when the one or more second parts are attached to the first part. The first part comprises an open-sided channel that corresponds to the first channel for at least some of its length. The nebuliser outlet assembly is configured such that when the one or more second parts are removed from the first part, said open-sided channel is exposed.

Abstract: A nebuliser outlet (20) comprises one or more first channels (24), wherein the nebuliser outlet (20) is configured such that liquid received by the nebuliser outlet (20) can pass to one or more nebulisation regions via the one or more first channels (24), and one or more second channels (25), wherein the nebuliser outlet (20) is configured such that gas received by the nebuliser outlet (20) can pass to the one or more nebulisation regions via the one or more second channels (25). The one or more first channels (24) comprise a first portion (24a) and a second portion (24b), wherein the first portion (24a) comprises a tubular channel, and wherein the second portion (24b) comprises multiple channels, an annular channel, or a segmented annular channel. The one or more second channels (25) converge with the second portion (24b) at the one or more nebulisation regions.
