Classification of SPE column
Polymer matrix series SPE
With spherical polymer as adsorbent, sorbent particle size is more uniform, SPE column flow rate is more stable, which is the classical polymer column in the laboratory, the whole series of products have been widely used in food testing. Products are equivalent to Waters’ HLBS, MAX’s and MCX’s.
Silica gel matrix series SPE
Classic silica gel matrix SPE column, amorphous/spherical adsorbent, with high cost performance and good user experience by the customer trust.The products are widely used in chemical analysis.
Tip extraction/purification/concentration of SPE
it is a spear pipetting device with function is applied for extract/purification enrichment biological samples or the Tip of SPE, objective product pipetting spear top add some C4 / C18 / silicon powder/magnetic beads/ProtingA (G) agarose gel sorbent, used for primer/genomic DNA plasmid PCR products/peptide protein/antibodies to target product/filter/extraction/desalting/purification/enrichment.
96/384-hole plate series SPE
The 96/384-well plate series SPE developed specifically for high-throughput sample pretreatment.Complete the sample pre-processing process with the company’s orifice filter or automatic workstation.
Special detection series SPE
Azo dye special detection column: choose ultra-pure diatomite filler;Special sieve-plate flow rate control technology, through the domestic and foreign authoritative institutions testing, OEM supply.
In addition, there are graphitized carbon black, acid alkali neutral alumina, coconut shell activated carbon, honey detection column, leather decolorization column, plasticizer detection column……SPE column, more SPE products please inquire.
Steps (take Tip SPE as an example) :
The operation is slightly different depending on the retention mechanism of sorbent with adsorption of target products or impurities
1. The sorbent adsorbs the target product, removes impurities and eludes the target product
loading sample cleaning, rejection washing, elution
This type of solid phase extraction operation generally has four steps:
(1) activation — removal of impurities in Tip SPE and generation of certain solvent environment;
(2) load sample — dissolve the sample in a certain solvent, use pipette to inhale the Tip SPE and keep the components on the Tip;
(3) leaching – maximum removal of impurities and other non-target products;
(4) elution – elution and collection of the target product with a small volume of solvent.
2. The sorbent adsorbs impurities and removes the target product
Adsorb impurities on the sample and expel the target product
This type of solid phase extraction usually has three steps:
(1). Activation — remove impurities in Tip SPE and generate a certain solvent environment.
(2) loading sample — inhale Tip SPE with pipette and then slowly blow it out. At this time, most of the target compounds will be blown out with the sample base solution, and impurities will be retained on Tip. Therefore, the steps should be started to collect.
(3) Elution — eluting the components with a small volume of solvent and collecting, combining the collection liquid.
