The Metrohm 874 Oven Sample Processor is an automated thermal sample preparation system designed to support Karl Fischer titration by heating samples to release moisture that is then transported to the titration cell for accurate water content determination. This oven-based method is especially useful for samples that are difficult to dissolve, sparingly soluble, or that react with titration reagents, allowing moisture to be expelled without direct contact with the reagent.
The system can be used with appropriate titration modules and accessories, including heated transfer tubes, sample racks, and septa, to provide a complete workflow for moisture analysis.

Key Highlights
- Automatic thermal sample preparation for Karl Fischer titration workflows.
- Ideal for samples that release moisture only at higher temperatures or are difficult to dissolve.
- Works with hermetically sealed sample vials to maintain water content until analysis.
- Moisture is released as vapor and carried to the titration cell via a carrier gas stream.
- Can be controlled via software (e.g., tiamo) for programmable method runs and data management.
- Includes or supports a range of titration accessories such as heated tubing, drying flasks, and septa.
- Compact footprint suitable for analytical labs.
