In many different applications, the need to determine the composition of a known or unknown compound is important. For plastics and resins, the best option to determine the composition is through Thermogravimetric Analysis or TGA.
TGA analysis uses increasing temperature over time to determine the change in the specific sample material. As each different component will have different chemical as well as physical property changes at specific temperatures, the method can be used to determine the components with accuracy and efficiency.
There are a specific protocol and practice that must be used for accuracy with TGA analysis. As with any type of testing, there are multiple factors that can come into play that may impact the test results. Working with a top testing lab will be the central issue, but determining how to evaluate labs can be a bit more of a challenge.
Avoid Choosing On Price
A big mistake that many customers make when looking for a lab for any type of polymer, plastic or resin testing and analysis is to shop based on price alone. In testing services, you will largely get what you pay for.
The most advanced, state-of-the-art and cutting-edge equipment is costly, as is the need for experienced, certified technicians to complete test to exacting standards and protocols.
The very low-cost testing facilities, offering TGA analysis usually are operating with outdated equipment, low staff levels, and less experienced staff. Each of these factors can result in inaccuracies in testing.
One of the benefits of working with these materials is the extremely small samples required for the tests combined with the light weight. This means that there is no need to choose a lab that is located close to where you are.
Instead, look at labs across the country. Most of these top labs offer fast turnaround times for orders as well, with the option for expedited testing when required.
