Frequently Asked Questions
Q: What is the difference between a moisture balance analyzer and a Karl Fischer titrator?
A: Moisture balance analyzers use TGA to measure moisture content, while Karl Fischer titrators use a chemical reaction to determine the water content of samples.
Q: How often should I calibrate my moisture balance analyzer?
A: Regular calibration is essential to ensure accuracy. Calibrate your analyzer at least once a month or more frequently if required by your application.
Q: Can I use a moisture balance analyzer to measure moisture in gases?
A: No, moisture balance analyzers are not designed to measure moisture in gases. Consider using a hygrometer or other specialized instrument for gas moisture analysis.
