SampliQ OPT




Polyamide chemistry		 Agilent SampliQ Optimized Polymer Technology (OPT) cartridges are appropriate for a broad range of samples, including weak acids, neutrals, and weak bases. SampliQ OPT utilizes a novel polyamide chemistry (patent pending) that makes OPT cartridges compatible with water and most organic solvents, as well as acidic and basic solvents with a pH level of 0 to 14. This resin technology also exhibits retention for both polar and non-polar compounds, based on its combined hydrophilic and lipophilic characteristics.

The predominant retention mechanism in OPT cartridges is reversed phase, which simplifies method development and compatibility for both GC and LC separations.

For hydrophilic compounds which are not effectively retained by OPT, try modifying the load and wash solvents by adjusting the pH to match the pKa of the poorly retained compound. For compounds that are too strongly retained, try adding 0.1% formic acid to the methanol eluent.

Unlike silica-based phases, OPT cartridges yield the same exacting results if they inadvertently dry out during the conditioning stage.
