Product Introduction:

Solid-Phase Extraction (SPE) is a widely used and highly popular sample pretreatment technique. It utilizes solid adsorbents to adsorb target compounds from liquid samples, separating them from the sample matrix and interfering compounds. The adsorbed compounds are then eluted or thermally desorbed using an eluent, achieving the goal of isolating and enriching the target compounds. Developed from traditional liquid-liquid extraction, it is based on the principle of "like dissolves like" and incorporates fundamental knowledge of widely applied liquid and gas chromatography stationary phases.

Product Features

1. Prevents cross-contamination with an anti-aerosol vacuum chamber design; simple and fast operation.

2. No phase separation required; easy collection of analytes and capable of handling small sample volumes.

3. The glass vacuum chamber is mold-formed, ensuring uniform wall thickness, allowing it to withstand high negative pressures exceeding -80 kPa.

4. The extraction column tray and collection rack are made of specially engineered polymer materials, offering an aesthetic appearance, corrosion resistance, and long-term usability under high-pressure conditions.

5. The vacuum device lid is made of imported polymer material, resistant to strong acids and alkalis.

6. The pressure regulating valve is crafted from imported polymer material, ensuring durability, corrosion resistance, and tolerance to high and low temperatures.

7. The product features a 12-position and 24-position design, making it more compact and practical.

8. Optional column adapter conversion fittings allow for direct rinsing and activation of solid-phase extraction columns using sampling tubes, making the process more convenient.
