摘要： A composite structure comprising a layer of zeolite having a high silica to alumina ratio supported on a support layer acts as a separator in a redox flow battery. The zeolite can be either supported on a rigid substrate, such as alumina, or a flexible substrate, such as a polymeric film. The polymeric film, in particular, can be an ion exchange membrane such as Nafion. The zeolite layer with a high silica to aluminum ratio provides a long-lasting separator for redox flow batteries.

摘要： A flow controller for use with a liquid chromatography detector. The flow controller includes a flow channel comprising an inlet portion, a control channel portion in communication with the inlet portion, and an outlet portion in communication with said control channel portion. The control channel portion has a cross-sectional area smaller than a cross-sectional area of a drift tube of the liquid chromatography detector for channeling the flow of droplets through the smaller cross-sectional area. The flow controller is shaped and sized to reduce pressure fluctuations and turbulence in the droplet stream of the liquid chromatography detector.

摘要： A focused droplet nebulizer of the invention produces substantially uniform droplets of a predetermined size. Droplets are pushed out through a small outlet orifice by the contraction of a chamber. The droplets can be carried on a substantially non-divergent path in a drift tube. A piezo membrane micro pump acts in response to an electrical control signal to force a droplet out of the outlet orifice. The nebulizer can operate at frequencies permitting a stream of individual droplets of the predetermined size to be sent along the substantially non-divergent path in the drift tube in a preferred embodiment ELSD device.

摘要： The invention relates to a non-invasive method to diagnose the changes of molecular structures of organism tissues from body surface and a dedicated apparatus. The apparatus is comprised of a Fourier Transform infrared spectrometer and a set of additional accessories. Said additional accessories include a mid-IR fiber optics sampling attachment, a fiber coupling part, and an infrared detector part. The detection method is comprised of placing the ATR probe of the dedicated apparatus on the skin surface of a region to be tested, and scanning more than one time in which the resolution of the apparatus is 1-32 cm−1 and the range of the spectrum is 800-4000 cm−1. It is possible to detect changes in molecular structures of living biological tissues in the early stages of cancer, and testees will not feel uncomfortable during testing. The method is easy to operate, quick, accurate, and it doesn't harm the body.

摘要： The invention concerns improvements in spectrophotometry. Aspects of the invention may be used independently or together to increase the sensitivity of spectrophotometry. One aspect of the invention is a spectrophotometer detection circuit. In this aspect of the invention, currents attributable to reference and sample beams are cancelled in the current mode. The detection circuit produces a first voltage proportional to the difference in currents and a second voltage proportional to one of the reference or sample beams. Both voltages are available to allow simultaneous measurement and analysis. Another aspect of the invention concerns thermal stability. According to the invention, thermal conductivity is established among the housing and optical system components to promote equilibrium. Another preferred embodiment has a unitary solid metal housing with a hollowed portion defined to mount and place optical system components. Recognition and identification of important noise sources in spectrophotometers forms an aspect of the invention contributing to the features and combinations of features in preferred embodiments. Many noise sources would not normally be considered in conventional spectrophotometry because the magnitude of particular noise sources dominates device performance.
摘要翻译：本发明涉及分光光度法的改进。本发明的各方面可以独立地或一起使用来提高分光光度法的灵敏度。本发明的一个方面是分光光度计检测电路。在本发明的这个方面，在当前模式下，归因于参考和采样光束的电流被消除。检测电路产生与电流差成比例的第一电压和与参考或采样光束之一成比例的第二电压。两种电压均可用于同时测量和分析。本发明的另一方面涉及热稳定性。根据本发明，在壳体和光学系统部件之间建立导热性以促进平衡。另一个优选实施例具有整体的实心金属外壳，其具有限定为安装和放置光学系统部件的中空部分。识别和识别分光光度计中的重要噪声源形成本发明的一个方面，其有利于优选实施例中的特征和特征的组合。常规分光光度法通常不会考虑许多噪声源，因为特定噪声源的大小主导器件性能。
