摘要： An apparatus and method for monitoring seal leakage within a fluid system, particularly well suited for high pressure liquid chromatography systems. The apparatus includes a liquid chamber (48) separated by a seal (49) from a wash chamber (58). A supply pump (51) supplies a uniform flow of wash solution from a reservoir (32) to the wash chamber (58). A return line (42) conveys a return flow from the wash chamber (58), including any leakage of fluid from the liquid chamber (48), through return line (42) to the reservoir (32). A detector (37) determines whether there is any differential between the unidirectional flow and the return flow.

摘要： An ion chromatographic apparatus and method for on-column preconcentration of trace ionic contaminants for quantitative trace analysis by ion chromatography. The method includes the multi-cycle, sequential steps of loading and purging of sample solution into and out of a sample injection loop (26) to cumulatively preconcentrate a separator column (30) with a cumulative amount of sample. Each purging step includes directing pressurized liquid, at a substantially constant rate and for a predetermined period of time to the sample injection loop (26), to drive up to about 98 % of the known volume of the sample solution from the sample injection loop (26). In turn, this flushed volume of sample solution passes through an ion exchange resin column (30) for concentration of the trace ionic contaminants in the resin.

摘要： An electrochemical cell comprises a chamber, an inlet port, an outlet port, an electrode port, and a counter electrode. The inlet port is configured to allow flow of a liquid into the chamber and through an inlet opening toward the working electrode, and the outlet port is configured to allow flow of a liquid out of the chamber and through an outlet opening. The device is configured so that a force applied to the working electrode slides the first end face of the working electrode to a distance from a face of the inlet opening due to the balancing force of a fluid flowing out of the inlet opening. The device may be used in a method for analyzing an analyte, such as one or more amino acids in a liquid sample.

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 eluent system as well as columns operated with a 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。此修改对于使用氢氧化物洗脱液系统运行的色谱柱以及用碳酸盐洗脱液系统操作的色谱柱非常有用。

摘要： A method of extracting an analyte from a sample is described. The sample is added to a sample container. A liquid solvent and a gas are added into the sample container. The addition of the gas is controlled to establish an elevated pressure within the sample container. The liquid solvent is heated to an elevated temperature that is below the boiling temperature of the liquid solvent at the elevated pressure. A type of gas is used that does not transition to a supercritical fluid at the elevated temperature and pressure used in the extraction process. The analyte can dissolve from the solid sample into the liquid solvent. Next, at least a portion of the liquid solvent containing the dissolved analyte can be removed from the sample container for subsequent analysis.
