Transpiration Control Technology is used to extend the shelf-life of a given product. Transpiration is the loss of water vapor through a container, it is a combination of water vapor that escapes through the opening and the walls of the container.
Transpiration results in an increase in the overall concentration as the actual analyte remains in the solution. Transpiration can be problematic because it creates a systematic error in the liquid inside the container. In the case of certified reference material, this can decrease the overall accuracy as the analyte concentration alters.
Why is Transpiration Control Technology Necessary?
Transpiration can be problematic because certified reference materials must be extremely accurate. Even if there are strict process controls in place during the manufacture, testing, and packaging of certified reference materials the final certified values will change due to transpiration when a bottle sits on a shelf for an extended period of time.
The process of transpiration can significantly alter the accuracy of these materials. And, what’s more, the rate of transpiration can drastically alter as a function of how full the bottle may be, the materials it's made of, the cap design, and more. This can ultimately lead to problems for the end-user.
Transpiration Control Technology addresses this problem, ensuring that the customer can gain accurate testing results.
How Does Transpiration Control Technology Work?
The rate of transpiration is a function of the bottle size and is proportional to the circumference of the opening divided by the weight or the percent fill of the bottle. Transpiration Control Technology is a function of the material construction and the temperature at which this material is stored.
Transpiration Control Technology Bags from Inorganic Ventures
Inorganic Ventures have always been at the forefront of producing highly accurate certified reference materials. Transpiration Control Technology bags act as a limitation on the environment that the bottle is exposed to. This means that any transpiration that has begun will stop once the bottle is placed in the bag and sealed. This is because equilibrium is reached between the vapor space and the bottle.
Transpiration Control Technology bags are plastic bags with aluminized coating on the inside. This creates a small microenvironment around the bottle, stopping transpiration from progressing.
This high-quality product does not negatively impact the certified reference material, in fact, it makes it even more accurate. The Transpiration Control Technology bag comes at no extra cost to the consumer, instead, it is an investment from Inorganic Ventures, ensuring that the shelf-life of a product is extended and there is more control for the user.
