Abstract
An ultraviolet-visible spectrophotometry (UV/Vis) high-performance liquid chromatography (HPLC) photometer includes a nano flow cell in which a light source feeds a reference light channel and a sample light channel, a reference photodiode for evaluating the reference light channel, and a sample photodiode for evaluating the sample light channel, which extends through the nano flow cell. To create a photometer whose signal evaluation is improved, respective effective exposure times of the sample photodiode and the reference photodiode are settable separately from one another.
Claims4
An ultraviolet-visible spectrophotometry (UV/Vis) high-performance liquid chromatography (HPLC) photometer, comprising:
- a nano flow cell in which a light source feeds a reference light channel and a sample light channel;
- a reference photodiode for evaluating the reference light channel;
- and
- a sample photodiode for evaluating the sample light channel, which extends through the nano flow cell, and
- wherein respective effective exposure times of the sample photodiode and the reference photodiode are settable separately from one another, and
- wherein reference measurement signal amplifiers for signals of the reference light channel and the sample light channel are settable separately from one another in terms of respective amplification factors for signals of the reference light channel and the sample light channel.
