    Abstract: The sensitivity of capillary flow cells such as described in the European patent application nr. 90200691.5 has been substantially improved by optimizing the alignment of the longitudinal section (middle part) of the bent fused silica capillary, by increasing the aperture ratio (flow cell diameter/flow cell length) and by making use of fiber optics for light beam guiding and enhancing the light propagation through the capillary flow cell.
    These improvements can be applied to any type of longitudinal flow cells including "Z" and "U" shaped capillary flow cells (Figure 1).
    The alignment of the middle part [2] of the bent fused silica capillary [3,4] is no longer parallel to the optical axes but shows a deviation by angle ψ - (Figure 2). This angle is of the same value as the angle by which the light beam is refracted during its entrance into the capillary glass tubing and, therefore, compensates for loss in refracted light.
    With aperture ratios (dc/Ic) of typically 1/260 the ratios are to far away from their optimum values of 1/10 to 1/5 and result in high noise levels.
    By adapting the ratios to values closer to the optimum (e.g. 1/40) noise levels can be reduced substantially.
    The use of fiber optics [6] allows for optimal light beam guiding to and from the capillary flow cell and increases the light throughput (Figure 3). Further it allows for placing the flow cell (sensing region) in distance to the detection device.
    This invention relates to a capillary flow cell for use in microseparation techniques such as capillary liquid chromatography, supercritical fluid chromatography, capillary electroseparations (e.g., capillary zone electrophoresis, micellar electrokinetic capillary chromatography, electrochromatography) and related techniques and to a method for manufacturing capillary flow cells of improved sensitivity.

    Abstract translation: 毛细管流动池的灵敏度，如欧洲专利申请nr。 通过提高孔径比（流动池直径/流动池长度）和利用用于光束引导的光纤来优化弯曲的熔融石英毛细管的纵向截面（中间部分）的对准，90200691.5已得到显着改善 增强通过毛细管流动池的光传播。 这些改进可以应用于任何类型的包括“Z”和“U”形毛细管流动池的纵向流动池（图1）。 弯曲熔融石英毛细管[3,4]的中间部分[2]的对准不再平行于光轴，而是以角度psi表示偏差（图2）。 该角度psi与入射到毛细管玻璃管道期间光束折射的角度具有相同的值，因此补偿折射光的损失。 通常孔径比（dc / lc）通常为1/260，这些比率将远离其1/10至1/5的最佳值，并导致高噪声水平。 通过将比率适应于更接近最佳（例如1/40）的值，可以显着降低噪声水平。 使用光纤[6]允许最佳的光束引导到毛细管流通池和从毛细管流动池引导，并增加光通量（图3）。 此外，它允许将流动池（感测区域）放置到距离检测装置的距离。 本发明涉及一种用于微分离技术如毛细管液相色谱，超临界流体色谱，毛细管电分离（如毛细管电泳，胶束电动毛细管色谱，电色谱法）和相关技术的毛细管流动池，以及用于制造毛细管流的方法 细胞提高灵敏度。

    Abstract: An optical sensor may include a sensor head that has an optical window for directing light into a flow of fluid and/or receiving optical energy from the fluid. The optical sensor may also include a flow chamber that includes a housing defining a cavity into which the sensor head can be inserted. In some examples, the flow chamber includes an inlet port defining a flow nozzle that is configured to direct fluid entering the flow chamber against the optical window of the sensor head. In operation, the force of the incoming fluid impacting the optical window may prevent fouling materials from accumulating on the optical window.

    Abstract: Systems and methods that facilitate analysis of superficial tissue based at least in part on a depth-selective fiber optic probe are discussed herein. The depth-selective fiber optic probe can include an illumination fiber for providing light to the superficial tissue, a collection fiber for collected reflected light, a ball lens that couples the fibers, and a protective overtube that houses the ball lens and fibers. The distances between the ball lens and fibers and between the fibers can be optimized based on several factors, such as by minimizing the illumination spot size, maximizing the overlap between the illumination and collection spots, and based on the angle between the illumination and collection beams.
