Sample combustion device

Sample combustion deviceIt is a pre-treatment combustion device used for "sample analysis". Large analytical instruments widely used in laboratories, such as atomic absorption spectroscopy, gas chromatography, ion chromatography, plasma spectroscopy, potentiometric titrators, elemental analyzers, etc., cannot directly analyze solid or liquid samples. Pre treatment must be performed on the solid or liquid samples to be analyzed. There are many methods for processing solid or liquid samples in the laboratory. The samples are placed in a closed container, burned, and the original sample is transformed from a solid or liquid state into a gas, which is dissolved in a certain solvent previously placed in the container, becoming the ion, atomic, or molecular state samples that can be detected by the above analytical instruments. This process of burning samples in a closed container is a commonly used sample pretreatment method.

Sample combustion deviceIt does not involve a specific analysis process, but simply places the sample in a closed container, ignites it, and undergoes sufficient self ignition. During the combustion process, the temperature continues to rise, eventually decomposing the original solid or liquid form of the sample into molecular, atomic, or ionic states. The obtained combustion products will dissolve in the solvent at the bottom of the container, thus obtaining the prepared sample. The basic principle of this instrument is to use temperature changes to process materials.

Working Principle:

The solid and liquid samples to be analyzed are placedBurning inIn the burning device, under sealed conditions, oxygen is filled and the sample is ignited with an igniter, and the sample is fully burned in the oxygen. The sample material after combustion will decompose into gas and dissolve in the solvent previously placed at the bottom of the combustion device. After the combustion process is completed, the oxygen bomb is placed in a water bucket to cool down, the oxygen bomb is turned on, and the solvent is removed, thus completing the sample combustion preparation process.
