QSE-24 Solid Phase Extraction Device Introduction: Solid Phase Extraction (SPE), also known as Solid Phase Extraction, is a widely used and popular sample pretreatment technique that selectively adsorbs target compounds from liquid samples using solid adsorbents, separating them from the sample matrix and interfering compounds, and then washing them with eluent to achieve the goal of separating and enriching the target compounds. SPE is developed on the basis of traditional liquid-liquid extraction (LLE) using the principle of similar phase solubility based on similar interactions between substances, combined with the basic knowledge of commonly used liquid chromatography (HPLC) and gas chromatography (GC) stationary phases. SPE solid-phase extraction is mainly used for processing liquid samples, for extracting, concentrating, and purifying volatile and semi volatile compounds in samples; When used for solid samples, the solid sample needs to be processed into a liquid state first. The QSE-12/24 solid-phase extraction device is designed based on the above principles and combined with practical usage processes. It improves the efficiency of sample pretreatment by carefully designing and facilitating user operation while ensuring the recovery rate of the target material. Technical parameters: 1. All channels are controlled by imported high-quality independent valves, which are durable and long-lasting. 2. Comes standard with 24 bit channels, and can be combined with multiple digits at will. 3. Each channel is equipped with an independent liquid circuit switch and an integrated guide pipe to avoid cross contamination. 4. Anti fogging glass vacuum chamber design, easy and fast operation. 5. Flexible to use, can handle individual samples or batch samples. 6. The vacuum chamber is made of thickened glass, with a pressure resistance of better than 80Kpa. 7. The specially designed vacuum chamber cover has the advantages of not being easily deformed and having strong corrosion resistance, and is equipped with a pressure gauge and a pressure regulating valve 8. Overall dimensions (mm): 338W × 145L × 208H. 9. Glass vacuum chamber size (mm): 268W × 100L × 150H. 10. Voltage resistance: better than 80KPa. 11. Matching test tube rack sizes: Ø 11mm, Ø 13mm, Ø 15mm, and lengths of 105mm or less.
