Abstract: This invention employs columns and methods to apply external and internal standards and compounds. Analytical standard or compounds are adsorbed to a solid phase extraction media and are stored indefinitely. The standards or compounds remain stable on the solid phase extraction media without decomposing. The standards or compounds may be removed from the solid phase extraction media with a solvent.

Abstract: In one aspect, the present invention provides a chromatographic stationary phase material for various different modes of chromatography represented by Formula 1: [X](W)a(Q)b(T)c (Formula 1). X can be a high purity chromatographic core composition having a surface comprising a silica core material, metal oxide core material, an inorganic-organic hybrid material or a group of block copolymers thereof. W can be absent and/or can include hydrogen and/or can include a hydroxyl on the surface of X. Q can be a functional group that minimizes retention variation over time (drift) under chromatographic conditions utilizing low water concentrations. T can include one or more hydrophilic, polar, ionizable, and/or charged functional groups that chromatographically interact with the analyte. Additionally, b and c can be positive numbers, with the ratio 0.05≤(b/c)≤100, and a≥0.

Abstract: Preparation and use of specialized nanoparticles containing tetrapods/graphene/metal organic frameworks, which are very effective at separating rare earth elements. Such methods and systems can be used for separating neodymium (Nd), Dysprosium (Dy), Praseodymium (Pr) and other REEs. Such metal organic frameworks may also be useful for separating other metals (e.g., so called critical metals). The metal organic framework (MOF) material is synthesized by solid phase reaction of metal oxide (e.g., ZnO) tetrapod or other nanostructured metal oxides, which are functionalized with nanoplatelet graphene, and a polyfunctional organic acid (e.g., an aromatic polycarboxylic acid). Such a resulting metallic organic framework exhibits high selectivity towards light REEs (e.g., Nd and Py), with lower selectively towards heavy REEs (e.g., Dy), allowing separation of such from one another.

Abstract: Titania nanotube arrays are useful for phosphopeptide enrichment and separation. These highly ordered titania nanotube arrays are a low cost and highly effective alternative to the use of liquid chromatography mass spectrometry (LC-MS) methods using meoporous titania beads or particles. The highly ordered Ti02 nanotubes are grown on surfaces coated with Ti metal, or preferably on Ti wires, by methods that preferably include anodic oxidation.
