ATDS-3440S Automatic Secondary Thermal Analysis Testing Machine
Descrição
Thermal analysis sampling is one of the most widely used sampling methods in gas chromatography (GC/MS),This product can be used in combination with the inlet of the current main flow and GC and GCMS made in China. There are a variety of gas and electric connections for users to choose,it is not only suitable for advanced laboratories of scientific research institutes, but also more suitable for those specialized fields (environmental monitoring, food and beverage, safety and forensic criminal investigation, cosméticos, agricultura, etc.) as routine analysis or Supporting selection of monitoring instruments
ATDS-3440S Automatic Secondary Thermal Analysis Testing Machine
Innovation points:
1. O sistema de amostragem multidimensional de passagem de gás com comutação de válvula rotativa supera as desvantagens das válvulas domésticas de seis e 10 vias, como vida útil curta e incapacidade de suportar altas temperaturas.
2. O projeto do processo do caminho do gás é muito simples, confiável, propício à prevenção de vazamentos, melhorar significativamente a eficiência do trabalho.
3. A tecnologia de tratamento inerte é adotada no caminho do gás e na válvula de amostra pela qual a amostra passa.
4. Caminho de gás opcional (Controle eletrônico de pressão EPC), display digital é mais intuitivo. It can realize automatic gas path system leak detection and fault alarm.
5. Ajustando o tempo de injeção, a amostra foi analisada para diferentes concentrações.
6. Para vários padrões, pode armazenar 10 métodos.
7. Tela colorida, interface amigável, operação de toque, pode ser dominado de forma rápida e fácil, todo o processo de operação de exibição de rastreamento, definir o valor do parâmetro e o valor em tempo real.
8. Expanda o escopo dos serviços:
(1) Provide customers with experimental equipment solutions, consultoria técnica ou co-construção e compartilhamento de projetos relacionados ao pré-tratamento de amostras de análise cromatográfica.
⑵ Pyrolyzer, functional module/unit assembly and related parts and accessories can be bought, rented or trade-in.
Campo de aplicação
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, additives, 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. Atualmente, 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, material, combustion
Material resources, comida, pharmaceuticals, polymers and a variety of other commodities, etc..
