| 摘要 |
A photometric or spectrophotometric apparatus and method wherein a sample is contained in a pipette held between two surfaces, one containing a photometric or spectrophotometric source and the other a photometric or spectrophotometric detector and an optical path is established through the walls of the pipette tip and through the sample between the two surfaces. Use of a disposable pipette tip which may be left attached to pipette tip during sample analysis or reattached to the pipette device following analyses, provides a means to recover the sample for subsequent applications and manipulations, and enables especially small volume samples to be analysed.
