Solid-Phase Extraction (SPE) sample pretreatment was developed from a combination of the liquid-solid extraction technique and liquid chromatography, which is mainly used for sample preparation, purification and concentration. SPE is widely used with different sample matrices which can be found in laboratories specializing in environmental water & soil, food, petrochemical, pharmaceutical, clinical, among others.

​

SepLine-S series automatic SPE instruments are available in either a Single or Dual channel design version. They are designed so that you can automatically complete the 4 steps of SPE.

1 Conditioning the sorbent,

2 Retention of compounds,

3 Rinsing to remove undesired compounds and

4 Elution of the analytes of interest.

A unique low-pressure sealing technology is applied to effectively control the column flow to prevent the solvent from mixing. Multi-channel mode can improve the SPE processing efficiency and guarantee the responsibility and stability of pre-treatment.
