Core components and performance requirements of Jiqun fully automatic solid-phase extraction instrument
Date: 2025-07-11Read: 0
Solid Phase Extraction (SPE) is a sample pretreatment technique widely used in fields such as environment, food, medicine, and biological analysis, which can effectively remove matrix interference and enrich target compounds.Jiqun Fully Automatic Solid Phase Extraction InstrumentWith its efficient, stable, and intelligent operational advantages, it has been widely used in laboratories. To ensure the long-term stable operation of the equipment and obtain high-quality extraction results, the performance of the core components is crucial.
1. Fluid system: the key to precise infusion
The liquid circuit system is the core power module of the fully automatic solid-phase extraction instrument, mainly composed of high-precision injection pumps or peristaltic pumps, pipelines, and valves. Its performance directly affects the accuracy and repeatability of solvent transport. Jiqun uses corrosion-resistant and anti-aging chemical inert material pipelines, and is equipped with a multi-channel pump system with adjustable flow rate to ensure that different solvents are accurately added according to the set procedures, avoid cross contamination, and improve the extraction efficiency.
2. Extraction column position and positioning device: ensure consistency of operation
As the carrier of solid-phase extraction reaction, the positioning device of the extraction column determines the stability of the entire process. Jiqun Instrument is equipped with a multi station extraction column bracket, which supports compatible use of multiple specifications of SPE columns and achieves accurate positioning through high-precision stepper motor drive. The system needs to have good repeatability accuracy to ensure consistency during each sample addition and elution process and avoid human errors.
3. Temperature control module: improve extraction efficiency and stability
Partial solid-phase extraction processes are sensitive to temperature, especially when involving thermal assisted extraction or volatile components, and temperature control modules are particularly important. The Jiqun fully automatic solid-phase extraction instrument usually integrates a constant temperature heating module, which can preheat the solvent and improve the extraction rate and recovery rate. The temperature control system should have a wide range of adjustment capabilities, high temperature control accuracy, and rapid response to ensure stable experimental conditions.
4. Control system and software interface: the foundation of intelligent operation
The control system is the 'brain' of the entire device, determining the degree of automation and ease of operation of the instrument. Jiqun devices generally use embedded control platforms, paired with Chinese touch screen operation interfaces. Users can customize extraction process parameters such as flow rate, time, temperature, etc., and support program saving and calling functions. The high-performance control system also has functions such as fault self checking and abnormal alarm, which enhance equipment safety and stability.
5. Safety protection and waste liquid treatment system: ensuring the safety of the experimental environment
Multiple organic solvents are used in the fully automated solid-phase extraction process, so safety protection and waste liquid treatment systems cannot be ignored. Jiqun Instrument focuses on leak prevention and volatilization prevention in its design, equipped with independent waste liquid collection channels and activated carbon adsorption modules, effectively reducing harmful gas emissions, protecting the health of experimental personnel and laboratory environment.
In conclusion,Jiqun Fully Automatic Solid Phase Extraction InstrumentThe five core components of the equipment - liquid circuit system, extraction column positioning device, temperature control module, control system, and safety protection system - together form the technical foundation for efficient operation of the equipment. Only with excellent performance and collaborative cooperation among various components can the automation, standardization, and high-throughput processing of solid-phase extraction be truly achieved, providing reliable guarantees for the pretreatment of complex samples.
