    • A method of operating a spectrometer to determine property and/or composition data of a sample comprises an on-line spectral measurement of the sample using a computer controlled spectrometer, statistical analysis of the sample data based upon a statistical model using sample calibration data, and automatically identifying a sample if necessary based upon statistical and expert system (rule-based) criteria. Sample collection based upon statistical criteria consists of performing a statistical or rule-based check against the model to identify measurement data which are indicative of chemical species not in the samples already stored in the model. Samples identified either by a statistical criteria or using an expert system (rule-based decisions) are used preferably to isolate the liquid sample using a computer controlled automatic sampling system. The samples can be saved for subsequent laboratory analysis in removable sample containers. The results of the laboratory analysis together with the on-line spectroscopic measurements are preferably used to update the model being used for the analysis.
    • 操作光谱仪以确定样品的性质和/或组成数据的方法包括使用计算机控制的光谱仪的样品的在线光谱测量,基于使用样本校准数据的统计模型的样本数据的统计分析,以及 根据统计和专家系统(基于规则)的标准,根据需要自动识别样本。 基于统计标准的样本收集包括对模型执行基于统计或基于规则的检查,以识别指示化学物质的测量数据,而不是在模型中已经存储的样品中。 优选使用统计标准或使用专家系统(基于规则的决策)鉴定的样品使用计算机控制的自动采样系统来分离液体样品。 样品可以保存,用于随后的可拆卸样品容器中的实验室分析。 实验室分析结果与在线光谱测量结果优选用于更新用于分析的模型。

    • A probe for fiber optic spectroscopy, having a radiation transparent window for the emission of radiation and an optical fiber that extends through the interior of a hollow housing, surrounds the fiber with a cushioning sleeve to provide an optical cable that preserves optical fiber connections and dampen vibration of the optical cable. The sleeve provides a structure around the optical fiber that is more compressible than the optical fiber and has a significantly greater mass than the optical fiber. Excess cable length may be provided along its path through the housing to impinge the cable against the interior walls of the housing and thereby dampen vibration by providing additional node points through contact of the sleeve with the housing wall. Helical twisting of the cable along its path through the housing further stabilizes the shape of the fiber optic cable within the housing and maintains a regular spacing of contact points with the housing. Regular spacing of node points consistently controls vibration dampening by contact between the housing wall and the cable.
    • 用于光纤光谱的探针具有用于发射辐射的辐射透明窗口和延伸穿过中空壳体的内部的光纤,用缓冲套筒围绕光纤,以提供保持光纤连接并阻尼的光缆 光缆的振动。 套管提供围绕光纤的结构,其比光纤更可压缩并且具有比光纤显着更大的质量。 可以沿其穿过壳体的路径提供过多的电缆长度,以将电缆撞击外壳的内壁,从而通过套筒与壳体壁的接触提供额外的节点,来抑制振动。 电缆沿其通过壳体的路径的螺旋扭转进一步稳定了光纤电缆在壳体内的形状,并保持与壳体的接触点的规则间隔。 节点的常规间距一致地通过壳体壁和电缆之间的接触来控制振动衰减。

    • A spectroscopic fluid sample cell for the transmission and detection of radiation with the key components being a housing; a centripetal acceleration chamber formed by the housing and extending through the housing for circulating a fluid through the housing over a curvilinear flow path about a rotational axis; a pair of windows aligned along a common axis intersecting a portion of the chamber and parallel to the rotational axis; a fluid inlet and a fluid outlet in communication with the centripetal acceleration chamber; and a flow director positioned in the housing to induce centripetal acceleration on fluid passing through the chamber and establish a radial composition gradient across the fluid chamber has been developed.
