It is designed to detect low absorbing substances in solution. The instrument uses a deuterium/tungsten light source with a user-selectable optical path length of 2, 10, 50 or 500 cm. The UltraPath system typically includes a Tidas I spectrometer module, a fibre optic light source, fibre optic cables and a Peri-Star Pro peristaltic pump. A sample is drawn into the sample cell by the peristaltic pump and absorbance of the solution at the selected path length is measured. Individual samples are separated by air bubbles, thereby minimizing cross-contamination."@en ; sdo:inDefinedTermSet ; sdo:name "World Precision Instruments UltraPath Ultraviolet spectrophotometer"@en ; sdo:termCode "SDN:L22::TOOL0460" .
