固相萃取仪是利用固体吸附剂将液体样品中的目标化合物吸附,与样品的基体和干扰化合物分离,然后再用洗脱液洗脱或加热解吸附,达到分离和富集目标化合物的目的（即样品的分离，净化和富集），目的在于降低样品基质干扰，提高检测灵敏度，其应用于各类食品安全检测、农产品残留监控、医药卫生、环境保护、商品检验、自来水及化工生产实验室。

主要特征:
●固相萃取仪整机由透明有机玻璃制作，耐腐蚀性强。
●真空槽其壁厚均匀故可承受-0.096Mpa以上的高负压，长期高压使用不变形。
●各处受压均匀，气密性好，稳定性强。
●萃取速度致性好、控制调整方便。
●多通道可控制，接头耐腐蚀。
●固相萃取仪内部试管架由聚四氟制成故有很高的耐腐蚀性。

Product introduction:

Solid-phase extraction apparatus is using solid adsorbent adsorption target compounds in liquid samples, matrix and interference with the sample of compound separation, next reoccupy eluent elution or heat desorption, reach the purpose of separation and enrichment of the target compounds (namely sample separation, purification and concentration), the purpose is to reduce the sample matrix interference, improve the detection sensitivity, applied to all kinds of food safety testing, agricultural residue monitoring, medicine, health, environmental protection, commodity inspection, tap water and chemical production laboratory.

Main features:

The solid phase extraction apparatus is made of transparent plexiglass and is highly corrosive.

The wall thickness of the vacuum tank can withstａnd the high negative pressure above -0.0996 Mpa, and the long-term high pressure is not deformed.

The pressure is uniform, the air tightness is good, the stability is strong.

The extraction speed is consistent and easy to control.

The multi-channel can be independently controlled and the joint can resist corrosion.

The internal test tube of the solid phase extractor is made of polyfluorine and has high corrosion resistance.
