  An optrode is provided for sensing dissolved gases or volatile components of a solution. A fiber optic is provided through which light from an associated light source is transmitted from a first end to a second end. A bubble forming means, such as a tube, is attached to the second end of the fiber optic, and an indicator material is disposed in cooperation with the bubble forming means adjacent to the second end of the fiber optic such that it is illuminated by light emanating from the second end. The bubble forming means causes a gas bubble to form whenever the optrode is immersed in the fluid. The gas bubble separates the indicator material from the fluid. Gases, or other volatile components, of the fluid are sensed as they diffuse across the gas bubble from the fluid to the indicator material.

  提供了一种用于感测溶液中溶解气体或挥发性成分的光学电极。 提供了一根光纤，相关光源的光通过该光纤从第一端传输到第二端。 气泡形成装置（如管）连接到光纤的第二端，指示材料与气泡形成装置配合放置在光纤第二端附近，使其受到从第二端发出的光的照射。 每当光学电极浸入液体中时，气泡形成装置会导致气泡形成。 气泡将指示材料与液体隔开。 当液体中的气体或其他挥发性成分穿过气泡从液体扩散到指示材料时，就会被感测到。

  A process monitors at least one hydraulic characteristic in a raw or waste water stream and/or system of said raw or waste water treatment process. At least one fluorescent specie(s) that has a maximum excitation wavelength of less than about 400 nm is added to a raw or waste water stream and/or system of said raw or waste water treatment process and at least one sample of water from said raw or waste water stream and/or system of said raw or waste water treatment process is analyzed for at least the presence of the fluorescent specie(s), and the presence of the specie of fluorescent specie(s) in such sample determines at least one hydraulic characteristic of the process.

  A concentration of microbiocides added to fluid systems is monitored by a fluorescence emission method which is based upon the measurement of the fluorescence intensity of an inert fluorescent additive which is added to the microbiocide composition prior to its introduction into the fluid system. Optionally, the fluorescent additive may be metered separately into the fluid system in direct proportion to the amount of industrial microbicide added. Biocide composition containing fluorescent additives are also disclosed. Preferably the fluid system is an industrial aqueous system.

  添加到流体系统中的杀微生物剂的浓度是通过荧光发射法进行监测的，该方法基于对惰性荧光添加剂荧光强度的测量，该添加剂在杀微生物剂组合物进入流体系统之前已添加到组合物中。可以选择将荧光添加剂按与工业杀微生物剂添加量成正比的比例单独计量到流体系统中。此外，还公开了含有荧光添加剂的杀菌剂组合物。流体系统最好是工业水系统。

  Fluorescence of a sample cell 20, 120, resulting from excitation by a diode laser 12 or a LED excitation source, 112 is imaged, optionally with a lens, 14, 114 onto a silicon photodiode detector 16, 116. An optical filter 18, 118 is placed between the sample cell and the photodiode detector to reject scattered excitation light. Output from the photodiode is amplified to produce an output voltage proportional to the quantity of fluorescence striking the photodiode detector. Since fluorescence is proportional to the concentration of a fluorophore present in a sample stream through hthe sample cell, and the concentration of the fluorophore is further proportional to a concentration of a chemical treatment agent or other additive present, then continuous monitoring of a voltage output allows real-time measurement of the amount of chemical treatment agent or other additive present in the sample stream.

  在二极管激光器 12 或发光二极管激发光源 112 的激发下，样品池 20 120 发出的荧光被成像（可选择使用透镜 14 114）到硅光电二极管检测器 16 116 上。在样品池和光电二极管检测器之间放置一个光学滤波器 18 118，以阻挡散射的激发光。光电二极管的输出经过放大，产生与照射到光电二极管探测器上的荧光量成正比的输出电压。由于荧光与通过样品池的样品流中荧光团的浓度成正比，而荧光团的浓度又与化学处理剂或其他添加剂的浓度成正比，因此对电压输出的连续监测可实时测量样品流中化学处理剂或其他添加剂的含量。
