Abstract
Abstract Apparatus removes bubbles from a sample of a liquid solution in order to use the sample for the measurement of concentration and/or a physical property of the solution. The apparatus includes a closed vessel and a porous partition for dividing the interior thereof into first and second compartments. The first compartment has an inlet and an outlet for passage of the bubbly solution. The solution passes through the first compartment while the sample penetrates the porous partition without accompanying bubbles. The second compartment has an outlet for the degassed sample.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
188 words
A degassing assembly for removing a degassed sample from a stream of bubbly liquid in order to introduce the degassed sample of the liquid into an analyzer or measuring device for the measurement of concentration and/or a physical property of the liquid, said assembly consisting of: a closed vessel, and a porous partition having interconnected pores located within said vessel and dividing the interior thereof into first and second compartments, the first compartment having an inlet and an outlet for the passage of the stream of bubbly liquid into and out of said first compartment and the second compartment having an outlet for the degassed sample of the liquid, said first and second compartments being only in liquid communication with each other through the pores in the porous partition, wherein the stream of bubbly liquid passes through the first compartment from the inlet to the outlet thereof while a portion of the liquid penetrates said porous partition from the first to the second compartment without accompanying bubbles, thereby removing from the stream of bubbly liquid the degassed sample which flows out of the outlet of the second compartment.
Claim 2
Dependent Claim
188 words
A degassing assembly for removing a degassed sample from a stream of bubbly liquid in order to introduce the degassed sample of the liquid into an analyzer or measuring device for the measurement of concentration and/or a physical property of the liquid, said assembly consisting of: a closed vessel, and a porous partition having interconnected pores located within said vessel and dividing the interior thereof into first and second compartments, the first compartment having an inlet and an outlet for the passage of the stream of bubbly liquid into and out of said first compartment and the second compartment having an outlet for the degassed sample of the liquid, said first and second compartments being only in liquid communication with each other through the pores in the porous partition, wherein the stream of bubbly liquid passes through the first compartment from the inlet to the outlet thereof while a portion of the liquid penetrates said porous partition from the first to the second compartment without accompanying bubbles, thereby removing from the stream of bubbly liquid the degassed sample which flows out of the outlet of the second compartment.
Claim 3
Dependent Claim
36 words
A degassing assembly according to claim 1 wherein the inlet of the first compartment is opposed to said porous partition whereby the bubbly liquid entering the first compartment through said inlet impinges against said porous partition.
Claim 4
Dependent Claim
39 words
A degassing assembly according to any one of claims 1 or 2 wherein said porous partition is a sintered porous body having pores of not more than 100 microns in diameter and a thickness of 1 to 30 mm.
