摘要： A cuvette for use with light scattering detectors is disclosed. A trough or moat within the cuvette can be filled with solvent which is not in fluid contact with the sample to be measured. This solvent moat creates saturated vapor pressure in the chamber preventing evaporation from the sample when the cuvette is capped. The cuvette itself may be made of an inexpensive polymer which can be polished to high optical quality while still being moldable in complex forms capable of enabling further utility, such as extra griping surfaces, identification tabs allowing the detection instrument to determine the cuvette model, and various sample chamber forms. The novel cuvette may have extremely small sample volumes, while allowing significant overfill of the measurement chamber, improving ease of sample loading. The polymers used may be relatively inexpensive, and therefore the cuvette can generally be discarded after a single use.

摘要： A novel filter housing assembly for use in liquid chromatography and similar fluid flow based systems capable of use at high pressure, well above 1000 psi, is disclosed. The filter housing assembly has a very low dead volume of approximately 11 μL and is capable of holding brittle ceramic filter membranes as well as flexible membranes without the support of a fit. The filter housing is capable of being assembled and disassembled by hand without the need of any tools and makes use of an inexpensive, disposable filter retaining screen.
摘要翻译：公开了一种用于液相色谱法和类似流体流动系统的新型过滤器壳体组件，其能够在高于1000psi的高压下使用。过滤器壳体组件具有非常低的死体积约11μm，并且能够容纳脆性陶瓷过滤膜以及柔性膜，而不需要配合。过滤器壳体能够用手组装和拆卸，而不需要任何工具，并且使用廉价的一次性过滤器保持屏。
