Embodiment Construction

[0040] Figure 1-3 An assembly 100 is shown comprising an analysis device in the form of a refractometer 150 and a flow cell 110 connected to the refractometer 150 . Refractometer 150 includes a housing containing a light source and other components (not shown) for measuring refractive index, and prism 155 defines a planar measurement surface 155a on which a multiphase fluid sample can be received , and the prism plate 156 surrounds the prism 155 so that only the flat measurement surface 155a is exposed. The prism plate 156 has a flat upper surface 156a higher than the flat measurement surface 155a and an inclined surface 156b extending from the upper surface 156a to the measurement surface 155a of the prism 155 to direct fluid towards the measurement surface 155a.

[0041] The flow cell 110 includes a housing 115 that includes a fluid chamber 120 having side walls 116 that define an interior volume 120a within the fluid chamber 120 . The housing also includes a lower surfac...

Abstract

A flow cell for use with an analytical device having a measurement surface onto which a fluid sample to be measured can be received comprises: a housing comprising an interface for connecting to an analytical device; a fluid chamber provided in the housing, the fluid chamber comprising sidewalls at least partly defining an internal volume for receiving a multiphase fluid sample and an opening arranged so as to provide a multiphase fluid sample received in the internal chamber volume to a measurement surface of an analytical device when the housing is connected to the analytical device; and anagitation device. The agitation device comprises an agitation mechanism adapted to agitate a multiphase fluid sample within the internal volume of the fluid chamber and cause movement of the fluid through and within the opening thereby providing fluid to a measurement surface of an analytical device. The agitation mechanism is separated from the internal volume by a barrier wall.

Description

technical field [0001] The invention relates to a flow cell, an assembly for measuring properties of a multiphase fluid sample and a method for measuring properties of a multiphase fluid sample. Background technique [0002] Analytical devices are used to measure the properties of materials to ensure they have specific compositions or properties. Certain analytical devices have a measurement surface on which a sample is placed for measurement. This usually requires the sample to be in a specific phase (such as solid or liquid) and to be homogeneous to ensure that a reading can be taken to ensure that the reading is accurate and representative of the entire sample. This can be particularly difficult if the sample is a multiphase fluid (eg, a fluid containing more than one phase) and is likely to revert to a certain state. where individual components (or groups of components) are separated or unevenly distributed, as this may hinder the measurement. [0003] Optical measure...
