SPE Vacuum Manifold

Solid phase extraction（SPE，Solid Phase Extraction）It is to purify the target substance by utilizing the differential adsorption ability of the analyte in different media, effectively separating the target substance from interfering components, greatly enhancing the analysis of the analyte, especiallytrace analysisThe detection ability of the substance has improved the quality of the tested samplerate of recovery.SPETechnology since the last century70Since its emergence in the late 1960s, it has developed rapidly and is widely used in fields such as environment, pharmaceuticals, clinical medicine, and food

⑤elutionThe World Walker launchedSPE-10AThe automatic solid-phase extraction device fully follows the working principle of solid-phase extraction and can process up to the same time each time6-12A sample. Throughout the entire sample processing process, the device uses a high-power, high-precision stepper motor to precisely control the flow rate of the small column, with an accuracy of up to

0.1ml/minThis fundamentally overcomes the traditional manual solid-phase extraction device (negative pressure or positive pressure), which is affected by the difference in resistance (pressure) between different small columns, resulting in a huge difference in flow rate between columns. The flow rate of a single small column cannot be accurately controlled, ultimately leading to the embarrassing result of wasting time, manpower, and material resources, but the experimental results cannot be guaranteed.at the same time8SPE-10A

The automatic solid-phase extraction device adoptsInch full touch screen control, can edit and save methods, up to ten extraction steps can be set, and extraction speed and volume can be independently set. During the extraction and rinsing process, each step is accompanied by a beep to remind users to proceed to the next step in a timely manner.In addition,SPE-10AThe automatic solid-phase extraction device adopts patented technology1PTE3Joint, also applicable to6，，，

10mlExtraction columns of different volumes allow users to freely switch between different products.

Characteristics of Automatic Solid Phase Extraction Device1. Adopting positive pressure stepper motor infusion technology to ensure stable flow rate, high precision, and repeatability;2. Semi automatic operation requires manual switching of solvents

SPE6Activation, loading, elution, cleaning, etc. of the column;123. HavingA（Extraction channel, capable of simultaneous extraction

6-12

A sample;

4. Support step-by-step elution function, which can achieve multi-step elution;

5. Can store ten methods, call up and use, automatically set;

6. All instrument operations are completed by the control panel, and operators only need to follow the prompts to change the liquid, greatly saving manpower;

7. Automatic cleaning function to avoid cross contamination

8. It can extract liquid samples such as groundwater, surface water, wastewater, fruit juice (even containing suspended solids);9. The performance is the same as that of fully automatic products, but the price advantage is obvious and the cost-effectiveness is higher;
