Introduction to sample pretreatment system

Sample pre-processing system refers to the equipment and technology for pre-processing and preparing samples before analysis, which mainly includes sample sampling, processing, cleaning, concentration, extraction and separation.
The sample pretreatment system usually consists of multiple parts, including:
1. Sampling device: used to obtain representative parts from the sample.
2. Processing device: used to process the original sample into a state suitable for analysis. For example, dehydration, crushing, mixing, shaking, etc.
3. Cleaning device: used to remove impurities and contaminants in the sample to ensure the purity and accuracy of the sample.
4. Concentration device: used to concentrate the target substances in the sample to a concentration suitable for analysis.
5. Extraction and separation device: used to separate target substances and interference substances in samples.
6. Storage and transfer device: used to save and transfer processed samples to avoid re-contamination and loss of purity.
The purpose of the sample pretreatment system is to remove interfering substances in the sample and enhance the sensitivity and accuracy of the analysis, thereby improving the quality and reliability of the analysis results. The system has the characteristics of automation, high-throughput, high degree of standardization and reproducibility, and is widely used in fields such as biology, chemistry, environment, agriculture, food and medicine.
