Suppose that the separation system consists of a branching channel with magnets along one side.
A triboelectrostatic separation system consists of a tribo-charging of materials and a separation of the charged materials in an electric field.
The selected separation system consisted of a micellar pseudostationary phase made by sodium dodecyl sulphate with the addition of γ-cyclodextrin.
Oversized material is rejected by screening and placed in waste piles, while the undersized material is distributed to a gravity-separation system consisting of riffled sluices, jigs, or similar equipment.
In order to increase separation efficiency and selectivity, the micelle system consisting of aqueous mixtures of ILs, Tween 20 and borate was optimized using a D-optimal design.
The aim of the present work is to evaluate the separation performances attainable with another electrode system, consisting of two metallic plates, a short one that is connected to the high-voltage and a long one that is grounded.
Alpha amino butyric acid was added to each extracted sample as an internal standard, the samples derivatized and analyzed using the AccQ Tag amino acid analysis system (Waters Corp., Milford, MA) using a Waters HPLC system consisting of a Waters Separation module 2695 with a Waters 2475 fluorescence detector.
Briefly, after pre-column derivatization using 6-aminoquinolyl-N-hydroxy-succinimidyl carbamate, the samples were injected to a HPLC system consisting of a 2695 separations module connected to a 2475 fluorescence detector (Waters).
Separation of peptides was achieved with a linear gradient system consisting of 20 40% solvent B (0.1% trifluoroacetic acid (TFA) in acetonitrile:water, 3 1) in solvent A (0.1% TFA in water) over 20 min.
Separation of the sample was performed on a Waters Acquity UPLC system consisting of a vacuum degasser, an autosampler with a cooled sample tray, a column oven, and a binary solvent manager with high-pressure mixing chamber.
The experiments were carried out using RP-HPLC-DAD (reverse phase high-performance liquid chromatography-photoiodide array detector) system consisting of a Waters 2695 Alliance (Milford, MA) separation module and a 966 photodiode array detector.
