| 摘要 |
<p>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.</p> |
