Elenert employs widely recognized fillers such as silica gel or bonded silica, where various functional groups are linked to silanol groups on the silica gel’s surface. With a pH range spanning 2.0 to 8.0, these silica-based phases offer an array of selectivity advantages due to their diverse functional groups, enabling multiple analytical possibilities.

The high molecular polymer is a copolymer material derived from the fusion of pyrrolidone and divinylbenzene. With its inherent polar functional group, pyrrolidone ensures a harmonious adsorption impact on diverse polar and non-polar compounds. Notably surpassing C18 columns, it boasts the following merits:

• Operational versatility from pH 0 to 12, without stringent activation controls; drying processes don’t compromise usage.
• Simultaneous adsorption of compounds spanning various polarity levels.
• Steers clear of low recovery rates attributed to intricate elution due to Si-OH interactions in compounds featuring basic groups.

Elenert QuEChERS series accomplish principle of dispersive solid-phase extraction to achieve rapid detection of pesticide residues and animal residues.
