固相萃取儀是利用固體吸附劑將液體樣品中的目標化合物吸附,與樣品的基體和干擾化合物分離,然后再用洗脫液洗脫或加熱解吸附,達到分離和富集目標化合物的目的（即樣品的分離，凈化和富集），目的在于降低樣品基質干擾，提高檢測靈敏度，其應用于各類食品安全檢測、農產品殘留監控、醫藥衛生、環境保護、商品檢驗、自來水及化工生產實驗室。
主要特征:
●固相萃取儀整機由透明有機玻璃制作，耐腐蝕性強。
●真空槽其壁厚均勻故可承受-0.096Mpa以上的高負壓，長期高壓使用不變形。
●各處受壓均勻，氣密性好，穩定性強。
●萃取速度致性好、控制調整方便。
●多通道可控制，接頭耐腐蝕。
●固相萃取儀內部試管架由聚四氟制成故有很高的耐腐蝕性。

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.
