摘要： Improved methods for drying for bio-compatible solid phase microextraction (BioSPME) coatings yielding coatings with highly consistent extraction efficiency and biocompatibility. The methods, adapted to flow-through drying systems involve determining relative humidity in and around the drying system, determining a drying temperature range based on the relative humidity, and maintaining the drying temperature within the determined range while drying the coating.

摘要： Treatment of anion exchange materials containing hydroxyl containing moieties in the beta position relative to the quaternary center in the hydroxide form with glycidol substantially alters the selectivity of the anion exchange material. Furthermore, sequential treatments of first a hydroxide containing solution to put the anion exchange material in the hydroxide form followed by treatment with glycidol in an alternating sequence progressively changes selectivity in a predictable manner allowing facile manipulation of selectivity. Unique to the selectivities achievable with this chemistry is the ability to reverse the elution order of sulfate and carbonate. With all other known systems, carbonate elutes ahead of sulfate and sometimes compromises the ability to quantitate sulfate. With glycidol treatment, carbonate can be moved after sulfate which eliminates interference issues for samples containing significantly more carbonate than sulfate. This modification is useful for columns operated with a hydroxide or carbonate eluent system.
摘要翻译：含有羟基的阴离子交换材料相对于具有缩水甘油的氢氧化物形式的季中心的β位置的处理基本上改变了阴离子交换材料的选择性。此外，首先连续处理含氢氧化物溶液以将阴离子交换材料置于氢氧化物形式，然后以交替的顺序用缩水甘油处理，以可预测的方式逐渐改变选择性，从而容易地操纵选择性。通过该化学可以实现的选择性独特的是反转硫酸盐和碳酸盐的洗脱顺序的能力。使用所有其他已知的系统，碳酸盐在硫酸盐之前洗脱，有时会损害硫酸盐的定量能力。通过缩水甘油处理，碳酸盐可以在硫酸盐之后移动，消除了含有比硫酸盐显着更多的碳酸盐的样品的干扰问题。该修饰对于用氢氧化物或碳酸盐洗脱液系统操作的柱是有用的。

摘要： A film for the retention and controlled release of organic or inorganic molecules consists essentially of a phyllosilicate clay and a organic polyanion. The film may be a built-up layered film of alternating layers of the clay and the polyanion. Organic or inorganic molecules are absorbed into the film from solution, and released in response to changes in the film's environment. The film may be built up using layer-by-layer (LbL) methods, or deposited on a substrate from a mixture of the clay and polyanion. Articles may be coated with the film by the same methods. The film is useful for the controlled release of antibiotics in response to infections, and also retains antibiotics such that bacteria may be killed by direct contact with the film.

摘要： In an embodiment, a method for manufacturing a thin layer chromatography (“TLC”) plate is disclosed. The method includes forming a layer of elongated nanostructures (e.g., carbon nanotubes), priming the elongated nanostructures with one or more adhesion priming layers, and at least partially coating the elongated nanostructures with a coating. The coating includes a stationary phase and/or precursor of a stationary phase for use in chromatography. The stationary phase may be functionalized with hydroxyl groups by exposure to a base or acid. The stationary phase may further be treated with a silane (e.g., an amino silane) to improve the performance of the TLC plate. Embodiments for TLC plates and related methods are also disclosed.

摘要： In an embodiment, a porous composite particulate material includes a plurality of composite particles. Each composite particle includes an acid-base-resistant core particle at least partially surrounded by one or more layers of acid-base-resistant shell particles. The shell particles are adhered to the core particle by a polymeric layer. The shell particles and/or core particles may be made from an acid-base-resistant material that is stable in harsh chemical conditions. For example, the shell particles and/or core particles may be made from diamond, graphitic carbon, silicon carbide, boron nitride, tungsten carbide, combinations of the foregoing, or other acid-base-resistant materials. The porous composite particulate materials disclosed herein and related methods and devices may be used in separation technologies, including, but not limited to, chromatography, and solid phase extraction.
