Yes, utilizing diode arrays gives rise to detecting a specified wavelength range without time de-lay in milliseconds. Averaging up to 200 spectra (see FAQ 1) per second yields excellent signal to noise ratio and allows detection of fast moving products in pipes or on conveyor belts (see figure 2). Therefore, measurement errors resulting from natural variance of the sample while averaging are excluded. Moreover, diode array based process analyzers do not contain any moving parts and are thus robust by design. They are perfectly suited for rough industrial conditions such as vibrations, extreme temperatures or humidity.
In a process environment diode array process analyzers are beneficial to scanning or interfer-ometer based technologies. Rotating wavelength filter wheels or Fourier Transform (FT) spectrom-eters with moving parts results in long measur-ing / averaging times and quality of measured data relies on stable surrounding conditions.
