1. Product introduction

The solid phase extraction device JC-GX-12 allows the liquid sample solution to pass through the adsorbent, retains the substance to be tested, and then selects a solvent of appropriate strength to flush out impurities, and then quickly elutes the substance to be tested with a small amount of solvent, so as to achieve rapid separation and purification. purpose of concentration. At present, it is mainly used in the analysis of organic substances such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in water, and the analysis of fruits, vegetables and herbicide residues.

2. Product parameters

1. Number of samples: 12

2. Control method: independent control

3. Pressure display: there is a pressure gauge

4. Vacuum degree: 0.098Mpa

5. Flow control valve: none

6. Work area size: ∮132X138 (mm)

3. Product Features

1. Anti-cross-contamination, anti-atomization vacuum tank design, simple and fast operation.

2. Operation without phase separation allows easy collection of analyte components and can handle small volume samples.

3. The solid phase extraction device can be equipped with a large-capacity collection container, which can process samples in batches or individually.

4. The vacuum tank is formed by extra-hard glass mold, and its wall thickness is uniform, so it can withstand high negative pressure above -0.085Mpa.

5. The extraction column tray is made of ultra-polymer material, which is beautiful and corrosion-resistant and will not deform under high pressure for long-term use.

6. The internal test tube rack is made of PTFE, so it has high corrosion resistance.
