2000年2月1日 · Two weirs within a sample channel formed a cavity in which octadecylsilane (ODS) coated silica beads (1.5-4 microns diameter) were trapped. ODS beads were mobilized into and out of the cavity using electroosmotic flow through a bead-introduction channel which accessed the cavity.

ODS柱是 十八烷基硅烷键合硅胶填料 （Octadecylsilyl，简称ODS）。这种填料在 反相色谱 中发挥着极为重要的作用，它可完成高效 液相色谱 70～80%的分析任务。由于C18（ODS）是长链烷基键合相，有较高的碳含量和更好的疏水性，对各种类型的生物大分子有更强的适应 ...

1994年12月30日 · The calcium ion-selective optodes developed were the flow-through type which were pre pared by packing pellicular ODS (octadecylsilica) beads in which they are coated with a lipophilic organic liquid incorporating the calcium ionophore and the anionic dye.

1999年9月20日 · In this sensing system, the ion-sensing layer was prepared with ODS-modified beads coated with a lipophilic organic liquid containing a neutral ionophore and a lipophilic anionic dye.

2007年2月12日 · Electrokinetic micropumps are fabricated using 6–8 μm ODS beads into 320–700 μm fused-silica capillaries. The fabricated bead column is characterized by measuring the porosity and tortuosity.

complex microfluidic manifold with beads has bindered the utilization of these ideal reagent delivery vehicles . Here we report on a design that utilizes micro weirs to reversibly trap reagent-laden beads within a microchip, while still allowing solution to flow through th e packed beads .

A novel microfluidic system has been developed for the trapping of bead-based reagents, enabling on-chip solid-phase extraction (SPE) and capillary electrochromatography (CEC). The system employs electroosmotic flow to mobilize silica beads coated with octadecylsilane (ODS), facilitating effective analyte retention and elution.

2022年7月2日 · By defining the light-exposure window on the channels, one can easily control the length and location of the polymer frits and the ODS beads can be packed at the desired location. With this method, solid phase extraction channels for microfluidic use can be easily prepared without complex fabrication of microstructures.

Two weirs within a sample channel formed a cavity in which octadecylsilane (ODS) coated silica beads (1.5-4 microns diameter) were trapped. ODS beads were mobilized into and out of the cavity using electroosmotic flow through a bead-introduction channel which accessed the cavity.

1994年8月3日 · Flow-through type fiber-optic chloride ion selective optodes have been developed based on chloride adducts of lipophilic organometallic compounds, including a metal: Sn, Ge, Hg or Hf and a lipophilic anionic indicator dye of the diphenyl amine type.
