Photo diode array detectors operate by simultaneously monitoring absorbance of solutes at different wavelength. Some analytical instruments produce a table of raw data which need to be processed into the analytical result. For an example, samples which do not have uv absorption, such as sugar, alcohol, or inorganic ions obviously cannot be measured by a uv. Similarly, with fluorescence detection, retention time and emission and absorption wavelengths are used for identification purposes. The limits of detection obtained by this device were compared to those obtained with a commercial fibre coupled led device. Fluorescence of a molecule can occur naturally or can be achieved by labeling the molecule with a fluorescent tag in a derivatization reaction. Although there are many specialized detectors, querying various parameters that can be used to interrogate samples coming off a liquid separation—from fluorescence to electrochemical to.

Detector • the detector can detect the individual molecules that come elute from the column. The diode array detector is similar to uv detector but can operate at a number of different wavelengths thereby providing increased specificity. Light of all wavelengths generated by the deuterium lamp is passed through the cell and then however, light falling on a discrete diode may not be derived solely from the incident light but may contain light generated by fluorescence excited.
