  • Publication number: 20230408465
    Abstract: A reconfigurable capillary liquid chromatography system includes a solvent delivery manager including a first solvent pump assembly including a first pump housing or mount. A base module is further provided including a base module housing which is user accessible, or a base module bracket, and an injection valve for sample injection to a liquid chromatography column. The injection valve has an inlet port for receiving a sample and the injection valve is mounted in or on the base module housing or the base module bracket. The solvent delivery manager is configured to deliver solvent to the injection valve. A reconfigurable control system is also provided for controlling the reconfigurable capillary liquid chromatography system.

  • Publication number: 20230002579
    Abstract: A porous polymer monolith comprises a polymer body having macroporous through-pores that facilitate fluid flow through the body and an array of mesopores adapted to bind from the fluid flow molecules of a predetermined range of sizes, wherein the surface area of the monolith is predominantly provided by the mesopores. Also disclosed is a method of making a porous polymer monolith. The method includes forming a polymer body by phase separation out of a solution containing at least a monomer, a crosslinker and a primary porogen, whereby the body contains multiple macroporous through-pores, wherein the solution further contains a secondary porogen comprising oligomers inert with respect to the monomer and cross-linker but chemically compatible with the monomer so as to form mesostructures within the polymer body during said phase separation, and washing the mesostructures from the body to provide an array of mesopores such that the surface area of the monolith is predominantly provided by the mesopores.

  • Publication number: 20200261887
    Abstract: A solid phase microextraction substrate is disclosed. The solid phase microextraction substrate has a sorbent coating on at least part of a surface thereof. The coating is adapted for extracting at least one analyte component from a fluid matrix. The coating includes sorbent particles in a polymeric adhesive matrix. A majority of pores in each sorbent particle in the coating do not contain substantially any of the polymeric adhesive matrices.

  • Patent number: 6319868
    Abstract: Porous zirconia or zirconium-containing particles, methods of making such particles and methods of using such particles including modifications to the surface of the particles are described. The method comprises heating zirconia particles to provide a substantially homogeneously liquid melt, quenching the particles of melt to effect spinodal decomposition to provide quench particles of a silica rich phase and a zirconia rich phase, annealing the quenched particles to provide non porous solid particles of zirconia and silica and, leaching the silica from these particles to produce porous solid zirconia particles comprising a three dimensionally substantially continuous interpenetrating network of interconnected pores.
