Solid phase extraction
SPE is a technology for separating and concentrating analytes from complex solutions, and it has been applied to many industries:
* Sample preparation for heavy metal analysis in groundwater
* Remove food and feed digestion solution impurities for better analysis of transition metals
* Remove impurities from blood and serum solutions for better analysis of heavy metal elements
* Concentrate or remove minerals from seawater samples
* Pre-concentration of water samples with SPE to increase sensitivity of XRF
* Reduce the weight of the water sample for easy carrying (just carry the small cartridge with the selected sample).

Cartridge capacity
The capacity of the SPE cartridge refers to the adsorption amount of the SPE cartridge packing. For silica-based SPE cartridge, the capacity is generally 1 to 5 mg/100 mg, that is, the cartridge capacity is 1%~5% of the mass of the packing. The capacity of the bonded silica ion exchange adsorbent packing is expressed in meq/g, that is, the capacity per gram of the filler is X milliequivalent. The capacity of such packing is usually between 0.5 to 1.5 meq/g.

SPE cartridge features
1. The particle size is highly uniform, the surface area and pore size are reasonable, and the optimized surface functional groups are highly stable in chemical properties.
2. High load, using less adsorbent and solvent, the result is more concentrated.
3. It is easy to use and reliable with high selectivity, good reproducibility and high accuracy.
