Are You in the Market for a... Thermal Analyzer?
Thermal analysis is the broad category of at least 20 techniques that measure some fundamental property of matter as a result of adding heat. For example, dilatometry measures volume changes upon heating, thermomechanical analysis quantifies the change in dimension of a sample as a function of temperature, and thermo-optical analysis detects changes in optical properties on heating or cooling.

Top 6 Questions You Should Ask When Buying a Thermal Analyzer
- If you are going to be analyzing x,y,z properties, ask if the company has any customers conducting the same type of work and if you can talk to them.
- Ask if you can submit a sample for a demo using specified conditions and, if so, how long this will take and whether a report will be provided.
- What type of post-sale application and technical support does the company offer, and how much will it cost you?
- What features distinguish the company’s instrument from their competitors’?
- What can the company tell you about the quality of the product, i.e., how was it manufactured and tested? This will help you determine the typical lifespan.
- What can the vendor tell you about the total cost of ownership, including expected consumables, software upgrades, service, and warranty costs?
