What is a Diode Array Spectrophotometer?

A diode array spectrophotometer is a type of single beam optical design that allows for rapid and simultaneous acquisition of a full UV/Vis spectrum. Unlike the traditional dispersive design, the diffraction grating in a diode array instrument is positioned after the sample, directly dispersing the transmitted light onto a diode array detector.

One of the key advantages of a diode array spectrophotometer is its ability to collect spectral data quickly. The grating in this instrument does not move or scan, allowing for continuous illumination of the array detector by the transmitted light from the sample. This enables fast data collection, with a full range UV/Vis spectrum acquired in milliseconds to seconds, depending on the instrument's design.

The Hewlett Packard 8452A Diode Array Spectrophotometer takes this technology to the next level with its advanced features and capabilities.

How Does a Diode Array Detector Work?

A diode array detector, such as the one used in the Hewlett Packard 8452A, consists of a linear array of discrete photo diodes on a single integrated circuit chip. These photo diodes act as light sensors, detecting the intensity of light at different wavelengths.

When the transmitted light from the sample illuminates the array detector, each diode detects the intensity of a specific wavelength. This information is then converted into an electronic signal, which can be processed and analyzed to generate a UV/Vis spectrum.

The diode array detector in the 8452A allows for the simultaneous detection of multiple wavelengths, enabling rapid and comprehensive spectral data collection.
