1-Naphthaleneacetic acid (NAA) Separation on Primesep and Obelisc Mixed-Mode Columns

August 28, 2015

 

 

1-Naphthylacetic acid (NAA) is a synthetic plant hormone which is useful for promoting growth and propagating leaf and stem cuttings. Auxins can prevent early thinning and dropping of fruits from stems. But at slightly elevated levels, it can be toxic to plants and animals. A single residue method was developed using QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) method, to be used by EURL (European Union Reference Laboratory). 1-Naphthylacetic acid was separated by both Obelisc R and Primesep 100. Primesep 100 is a reverse-phase column with embedded acidic ion-pairing groups while Obelisc R is a mixed-mode column with separates using ionic groups and a long hydrophobic chain. Methods are LC/MS compatible and able to be used with many pesticides.

Application Column

Obelisc R

SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.

Primesep 100

The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers. Inquire about our specially-tailored custom LC-phases for specific separations.
