FAQ's of Metrohm 831 KF Coulometer:

Q: How does the Metrohm 831 KF Coulometer determine moisture content in samples?

A: The Metrohm 831 KF Coulometer uses coulometric Karl Fischer titration, automatically detecting the endpoint through polarization and compensating for drift, which ensures highly accurate moisture measurements within 0.1 bcg to 200 mg H2O.

Q: What benefits does automatic drift correction provide during analysis?

A: Automatic drift correction enhances analytical reliability by continuously compensating for background moisture and environmental changes during titrations, leading to consistently precise and reproducible results.

Q: When should the device's data storage and printer interface be utilized?

A: Data from up to 100 titrations can be stored internally and exported via the RS232 interface. Use these functions when traceability, regulatory compliance, or further data analysis is required in laboratory operations.

Q: Where can the Metrohm 831 KF Coulometer be applied effectively?

A: This instrument is ideal for moisture determination in laboratories across several sectors including pharmaceutical, chemical, food, and oil industries, offering reliable results for various sample types and compliance needs.

Q: What is the process of sample introduction in the instrument?

A: Samples can be introduced either manually or using an external dosing system, providing flexibility based on sample nature and laboratory workflow preferences.

Q: How does the instrument ensure compliance with regulatory standards?

A: The Metrohm 831 KF Coulometer is compliant with GLP, GMP, and pharmacopoeia guidelines. It also offers optional 21 CFR Part 11 support for electronic records and signatures, meeting the strict demands of regulated industries.
