Water uptake measurement system
A water uptake measurement system for measuring uptake of a fluid by a sample includes a sample chamber, a suspension component and a supply interface. A suspension aperture is located at a first end of the sample chamber and extends from an outer surface of the sample chamber to an inner surface of the sample chamber. The suspension component passes through the suspension aperture and is configured to support the sample within the internal cavity such that the sample is spaced apart from the inner surface of the sample chamber. The supply interface is configured to deliver the fluid to the internal cavity of the sample chamber.
1. A water uptake measurement system for measuring uptake of a fluid by a sample, comprising:
a sample chamber having an outer surface, an inner surface, an internal cavity having a controlled temperature and humidity, and a suspension aperture that is located at a first end of the sample chamber, wherein the suspension aperture extends from the outer surface of the sample chamber to the inner surface of the sample chamber;
a suspension component that passes through the suspension aperture of the sample chamber such that a first end of the suspension component is located in an ambient temperature and humidity area outside of the internal cavity of the sample chamber and a second end of the suspension component is suspended within the internal cavity of the sample chamber, wherein the suspension component is configured to support the sample within the internal cavity such that the sample is spaced apart from the inner surface of the sample chamber, and the suspension aperture is sized and configured to allow the suspension component to pass therethrough and to minimize temperature and humidity losses from the internal cavity to the ambient temperature and humidity area; and
a supply interface that is configured to deliver the fluid to the internal cavity of the sample chamber.
2. The water uptake measurement system of claim 1 , further comprising:
a vent interface that is configured to remove the fluid from the internal cavity of the sample chamber.
3. The water uptake measurement system of claim 2 , wherein the vent interface include a valve that is configured to selectively interrupt flow of the fluid from the internal cavity of the sample chamber.
4. The water uptake measurement system of claim 2 , wherein the vent interface is in fluid communication with the internal cavity through a vent aperture located adjacent to the first end of the sample chamber.
5. The water uptake measurement system of claim 1 , wherein the supply interface includes a valve that is configured to selectively interrupt flow of the fluid to the internal cavity of the sample chamber.
6. The water uptake measurement system of claim 1 , wherein the supply interface is in fluid communication with the internal cavity through a supply aperture located adjacent to a second end of the sample chamber that is located opposite the first end of the sample chamber.
7. The water uptake measurement system of claim 1 , further comprising:
a sensor that is mounted to the sample chamber for detecting a condition within the internal cavity.
8. The water uptake measurement system of claim 7 , wherein the sensor is mounted at the first end of the sample chamber.
9. The water uptake measurement system of claim 7 , wherein the sensor detects at least one of temperature or relative humidity.
10. The water uptake measurement system of claim 1 , further comprising:
a heating element that is in contact with the outer surface of the sample chamber.
11. The water uptake measurement system of claim 10 , further comprising:
an insulating component that is connected to the sample chamber such that the heating element is positioned between the sample chamber and the insulating component.
12. A water uptake measurement system for measuring uptake of a fluid by a sample, comprising:
a sample chamber having an outer surface, an inner surface, an internal cavity, and a suspension aperture that is located at a first end of the sample chamber, wherein the suspension aperture extends from the outer surface of the sample chamber to the inner surface of the sample chamber, wherein the sample chamber includes a removable portion that is selectively separable from a base portion of the sample chamber;
a suspension component that passes through the suspension aperture of the sample chamber such that a first end of the suspension component is located outside of the internal cavity of the sample chamber and a second end of the suspension component is suspended within the internal cavity of the sample chamber, wherein the suspension component is configured to support the sample within the internal cavity such that the sample is spaced apart from the inner surface of the sample chamber; and
a supply interface that is configured to deliver the fluid to the internal cavity of the sample chamber.
13. The water uptake measurement system of claim 12 , wherein the removable portion of the sample chamber threadedly engages the base portion of the sample chamber.
14. The water uptake measurement system of claim 12 , wherein the suspension aperture is defined through the removable portion of the sample chamber.
15. The water uptake measurement system of claim 12 , further comprising:
a gasket that seals the removable portion of the sample chamber with respect to the base portion of the sample chamber when the removable portion of the sample chamber is in engagement with the base portion of the sample chamber.
