by Lab Manager

Pharmaceutical and polymer industries are increasingly interested in both TGA (thermogravimetric analysis) and DSC (differential scanning calorimetry). Drug companies use these techniques to test for drug stability and crystalline state (or lack thereof). Thermal analysis is not only about high temperatures. Some instruments have a cooling function that enables monitoring of low-temperature events such as glass transition in polymers.

Top 6 Questions You Should Ask When Buying a Thermal Analyzer

1. 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.

2. 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.

3. What type of post-sale application and technical support does the company offer, and how much will it cost you?

4. What features distinguish the company’s instrument from their competitors’?

5. What can the company tell you about the quality of the product, i.e., how it was manufactured and tested? This will help you determine the typical lifespan.

6. What can the vendor tell you about the total cost of ownership, including expected consumables, software upgrades, service, and warranty costs?
