| 摘要 |
The present invention is directed to the use of a light absorbing wall material (4) to eliminate stray light paths in light-guiding structures, such as those used for HPLC absorbance detection. More specifically, the present invention relates to the use of carbon-doped Teflon ® AF, or "black Teflon ® AF", for all or part of the walls of a light-guiding flowcell (2) adapted for use in HPLC absorbance detection. |
