摘要： Embodiments disclosed herein are directed to gaseous mercury detection systems, calibration systems, and related methods. The gaseous mercury detection systems are configured to detect gas-phase mercury-compounds present in ambient air. For example, the gaseous mercury detection systems collect gas-phase mercury-compounds from ambient air and release the gas-phase mercury-compounds at concentrations capable of being measured by a gas-chromatography mass spectrometer without heating the gas-phase mercury-compounds above a decomposition temperature of at least one gaseous mercury compound that may present in the mercury-containing gas. The calibration systems are configured to determine an accuracy of or calibrate a gaseous mercury detection system. The disclosed calibration systems may be integrated with or distinct from the gaseous mercury detection systems disclosed herein.

摘要： In the invention, a collection device includes a flow through micro scale plate arranged to collect analyte. The plate includes holes, and sorbent coating on contact surfaces of the plate. The holes pass analyte fluid flow, for example analyte vapor so that fluid flow for collection may be generally perpendicular to the sorbent plate. Preferred embodiment plates include an integrated heater trace. In preferred embodiments, a high substantially perpendicular flow is used for collection and concentration, and during desorption and delivery a low substantially parallel flow is used. The low flow is selected to meet constraints of a detector system.

摘要： A system and method for extracting headspace vapor is generally disclosed comprising pressurizing a vessel containing headspace vapor with a carrier gas and subsequently venting the sample mixture through an adsorbent trap and out a vent. A flow controller is employed to gradually increase the flow therethrough as the pressure drops as a result of the gradual depletion of headspace vapor in the vessel and, in certain embodiments, the flow controller maintains a constant flow rate. Due to the time saved, in some embodiments, multiple pressurization-venting cycles are implemented to maximize the amount of vapor extracted from the vial. Due to the constant flow rate, in certain embodiments, the pressure decay is monitored and compared to reference values in order to determine whether the sample vessel has a leak or other defect.
摘要翻译：通常公开了一种用于提取顶空蒸气的系统和方法，包括用载气加压含有顶空蒸气的容器，随后将样品混合物通过吸附剂阱并排出出口。采用流量控制器随着压力下降而逐渐增加流量，这是由于容器中顶部空气蒸气逐渐消耗的结果，并且在某些实施例中，流量控制器保持恒定的流速。由于节省了时间，在一些实施例中，实施多个加压 - 排气循环以最大化从小瓶中提取的蒸气的量。由于恒定的流速，在某些实施例中，监测压力衰减并与参考值进行比较，以确定样品容器是否具有泄漏或其他缺陷。

摘要： A fluid analyzer having a concentrator and separator for concentrating and separating fluid samples at pressures up to about 10,000 psi (null700 bar). The concentrator and separator may consist of a solid-state thin-film heater-adsorber and a channel supported by a solid substrate. The concentrator may have numerous heated interactive elements for adsorbing and desorbing constituents of a sample fluid. The interactive elements may be heated in a time phased sequential manner by heaters. The separator may separate the sample fluid by compound. There may be thermal conductivity detectors, a flow sensor and electrical conductivity detectors proximate to the channels. This system of concentrator, separator, heaters and sensor may provide information about the sample fluid composition. A pump may be connected to the channel to move the sample fluid through it.
