Abstract
An apparatus for use in determining the presence and/or concentration of one or more selected materials in a matrix stream of materials within a process pipe, reactor or other process vessel, including (a) a support member having a first, internal end for inserting into the matrix stream when the apparatus is placed in service and a second end positioned externally of the pipe, reactor or other vessel in use, wherein the support member defines a groove therein of which at least a portion extends into the matrix stream in use, and (b) a conduit, for example a capillary membrane, positioned and supported substantially wholly within at least that portion of the groove in the support member which extends into the matrix stream in use.
Claims25
An apparatus for use in determining the presence and/or concentration of one or more selected materials in a matrix stream or aggregation of flowable materials within a process pipe, reactor or other process vessel, comprising:
- a support member having a first, internal end for inserting into the matrix stream or aggregation of flowable materials when the apparatus is placed in service and a second end positioned externally of the pipe, reactor or other process vessel in use, and wherein the support member underlies and defines a groove in and along an external surface thereof of which at least a portion extends into the matrix stream in use;
- and
- a conduit which is adapted to be placed in communication with an analytical device external of the process pipe, reactor or other process vessel and which is positioned and supported substantially wholly within at least that portion of the groove in the support member extending into the matrix stream or aggregation in use, whereby the conduit may be placed in contact with the matrix stream or aggregation of flowable materials while being protected by and supported within such groove portion.

- and
- analytical means, associated and in communication with the conduit in use, for determining the presence and/or concentration of the one or more selected materials.
