Max Pressure: 9000 psi（62Mpa）
Flow rate: 0.001 -10.000 mL/min（0.001mL/min)
Flow rate Accuracy: ≤0.06% RSD(ASTM)
Flow rate Precision: ±0.2%
Pressure Pulsation: ≤1%
Isometric pump is a commonly used instrument and equipment in liquid chromatography analysis. It is mainly used to transport mobile phases. Its application areas are as follows:
Chemical Analysis
Drug Analysis: In drug research and development, production quality control, and drug metabolism research, isometric pumps can accurately transport mobile phases to ensure the accuracy and repetition of high-performance liquid chromatography (HPLC) analysis, thereby conducting qualitative and quantitative analysis of drug ingredients. For example, in the determination of the content of drugs such as aspirin, an isometric pump can stably transport the mobile phase, so that the drug components are well separated and detected.
Environmental pollutant analysis: used to analyze pollutants in the environment, such as pesticide residues in water, polycyclic aromatic hydrocarbons in soil, etc. Through isometric pumps, the flow rate and composition of the mobile phase can be accurately controlled, and effective separation and detection of trace pollutants in complex environmental samples can be achieved, providing strong support for environmental protection and monitoring.
Food ingredients analysis: In the food industry, it can be used to analyze nutrients, additives, and harmful substances in food. For example, by detecting vitamins, preservatives, pigments and other ingredients in food, isometric pumps can ensure the stable supply of mobile phases, which helps accurately analyze the ingredients and quality and safety of food.
Biological analysis
Protein and polypeptide analysis: In the fields of biochemistry and molecular biology, isometric pumps are commonly used for the isolation and analysis of proteins and polypeptides. By combining with suitable chromatographic columns and detection methods, separation can be carried out based on the size and charge characteristics of proteins and peptides, providing important technical support for protein structure research, proteomic analysis, etc.
Nucleic acid analysis: In nucleic acid research, such as the isolation and analysis of DNA and RNA, isometric pumps also play an important role. It can accurately control the conditions of the mobile phase and achieve the separation of nucleic acid molecules of different lengths and base compositions. It is often used in experiments such as gene sequencing and nucleic acid purity detection.
Isometric pumps have important applications in various analytical fields where precise control of liquid flow is required and are one of the key equipment for efficient and accurate separation and analysis.
