| 摘要 |
<p>The present invention relates to flow-through cell for qualitative or quantitative optical analysis of physical or chemical properties of different liquid, fluid, paste, or powder compositions, using a conveying conduit essentially composed of PTFE or other optically transparent or translucent material, such as other fluorinated polymers, and through which passes a light pathway. The light pathway can passes through an entire conveying conduit or through a section thereof. The light wavelength used in this flow cell apparatus can be selected from infrared to visible light spectra. The light passing through the composition is received, transmitted and translated into an interpretable form.</p> |
