Shanghai Xinzhuang Instrument Co., Ltd. has developed an advanced automated solid-phase extraction (SPE) system that offers both 12- and 24-channel configurations, allowing for unified control while maintaining individual channel operation. This innovative technology is designed to streamline the sample preparation process, making it more efficient and accurate. SPE is a widely used technique in analytical chemistry that involves using a solid adsorbent to selectively capture target compounds from a sample matrix, effectively removing interfering substances before elution with a suitable solvent. Building upon traditional liquid-liquid extraction (LLE), SPE leverages the principles of chromatography, particularly those found in high-performance liquid chromatography (HPLC) and gas chromatography (GC). By utilizing stationary phases, SPE enables the separation and concentration of analytes, especially volatile and semi-volatile compounds, from complex sample matrices. The technique can be categorized into four main types: reverse-phase SPE (RP-SPE), normal-phase SPE (NP-SPE), ion-exchange SPE (IE-SPE), and adsorption-based SPE. Depending on the nature of the sample, SPE is typically applied to liquid samples, although solid samples must first be extracted into a liquid form before analysis. As the number of SPE procedures increases, manual operations become time-consuming and prone to human error, which can compromise the reproducibility of results. To address these challenges, Shanghai Xinzhuang has introduced a vacuum manifold system imported from the United States, integrated into their DG series solid-phase extraction devices. These systems allow multiple SPE processes to be carried out simultaneously without cross-contamination. The closed, anti-evaporation observation chamber ensures clarity and precision during the extraction process, enhancing overall efficiency and reliability. In addition to its SPE equipment, Shanghai Xinzhuang has also developed a wide range of laboratory instruments, including low-temperature constant temperature devices, ultrasonic units, box-type instruments, microbial testing tools, ice-making refrigeration systems, and various other lab support equipment. With a strong foundation in scientific instrument development and continuous technological innovation, the company is committed to providing high-quality solutions tailored to the needs of modern laboratories.
