Solid phase extraction (SPE) has emerged as an appealing strategy among the sample treatment methods due to the versatility of sorbent materials, less solvent consumption, and compatibility with analytical devices and has served as an effective sample preparation technique in many fields as bioanalytical, drug purification, fine chemical preparation, food analysis, environmental analysis, and life science industry where it has risen as one of the most versatile modes of sample preparation, employing a unique combination of sorbent chemistry and elution conditions to bind, clean-up, and release analytes in simple, sequential steps. When done effectively, SPE can achieve three essential goals in an extraction: clean-up the matrix, concentrate the sample, and provide a solvent-switching mechanism to a more compatible mobile phase that is more compatible with mass spectrometry (MS) analysis. To meet & contribute to these industry’s needs, ELEGANCE Life Sciences has developed Elenert SPE products under the excellent technology of foreign parent companies. With more than 20 different chemistries that includes extraction mechanisms such as reverse phase, normal phase, ion-exchange, and hybrid which can meet the needs of analysts in the separation and purification process.
(1) Silica gel C18,C8,CN,NH2,PSA,SAX,SCX,Silica.
The most commonly used fillers in Elenert are silica gel or bonded silica (bonding different functional groups on silanol groups on the surface of the silica gel). Its pH range is 2.0-8.0. There are many kinds of silica-based phases, which has the advantage of multiple selectivites.
(2) Polymer HLB,MAX,MCX,WAX,WCX;
The high molecular polymer is a polymer material obtained by copolymerization of pyrrolidone and divinylbenzene. Due to the the polar functional group of pyrrolidone, it has a balanced adsorption effect on various polar and non-polar compounds. Compared with the C18 column, it has the following advantages:
(3) Adsorption Florisil (magnesium silicate), GCB (graphitized carbon), alumina (neutral, acidic, basic)
(4) Specialized column series, GCB/NH2 column, BAP (for benzopyrene), PAE (for plasticizer), TRF (for tea)
(5) QuEChERS method: Elenert QuEChERS series
Elenert QuEChERS series accomplish principle of dispersive solid-phase extraction to achieve rapid detection of pesticide residues and animal residues.
