应用领域

1. Composition of volatile aroma and flavor compounds in food, and determination of residues and pollutants in food.

2. Composition of thermally degradable compounds in solid substrates, such as plasticizers, 添加剂, monomers, ETC. (These sample degradation products are desorbed by adsorption thermal desorption

Analysis and determination are helpful to the detection of arson cases).

3. Unwanted components in the sample matrix, such as residual solvents in pharmaceuticals, residual monomers in polymers, and other oligomers.

4. Purposefully collect volatile components in the sample matrix, such as polluted atmosphere, salt and sugar. 现在, the typical application is to collect the volatiles in the air with adsorption tube

Machine pollutants (benzene series, VOCs) are used to monitor the environment.

5. A thermal analysis, generally only used for lower boiling temperature components (C2 ~ C13), inorganic and gas is not easy to do. If using low temperature adsorption trap (secondary thermal analysis)

Can achieve boiling point < C36 volatile samples.

6. It can also be used for special solids and liquids (such as dipping cotton into the tube).

7. Secondary adsorption thermal desorption sampling combined with GC/MS, has a wider range of applications, can solve the analysis and determination of complex types of samples, including environment, 材料, combustion

Material resources, 食物, pharmaceuticals, polymers and a variety of other commodities, ETC.
