Planning Microwave Digestion Batches

A microwave digestion batch needs compatible vessels, a defined acid procedure and a controlled heating program. HM-WB12 monitors temperature and pressure during digestion. The vessel loading and program must follow the approved procedure for the sample material.

A practical measurement workflow

1. Select the validated digestion method and inspect the vessels and sealing components.
2. Load samples, reagents and controls within the method limits.
3. Run the specified heating program and retain the temperature and pressure records.
4. Cool and open vessels according to the instructions, then prepare the digest for analysis.

How the measurement works

Microwave digestion is a sample preparation step that uses controlled heating in suitable vessels. The HM-WB12 record describes temperature and pressure monitoring, programmable heating and individual vessel pressure-relief arrangements. The prepared digest is subsequently analyzed using the intended analytical instrument.

Manufacturer-listed configuration

The HM-WB12 from HM Instruments provides the example configuration in this guide.

Interpreting the result

The listed temperature and pressure specifications describe equipment capability. Actual sample loading, reagent quantities and operating limits follow the approved vessel and digestion procedure.

Common questions

Does digestion directly give the metal concentration?

The digest is measured by the appropriate downstream analytical method.

Are all vessel positions available for unknown samples?

Reserve capacity for blanks, reference materials, duplicates and other required controls.

Retain the sample identity, method settings and control results with the reported measurement. Use the operating procedure supplied for the selected configuration.
