The sub types of the AnalyserDeviceType are illustrated in Figure 6. Each of these sub type may be further sub typed.


Figure 6 - AnalyserDeviceType Hierarchy

The AnalyserDeviceType is derived from the DeviceType as an Abstract type. It is sub-typed for each one of the analyser classes. Six sub-types are introduced:

A light spectrometer is an optical instrument used to measure Properties of light over a specific portion of the electromagnetic spectrum (IR/NIR/VIS/UV), typically used in spectroscopic analysis to identify chemical composition of sample materials. The use of analytical techniques to determine process control parameters from spectra allows a wide range of industrial applications. This type covers FTIR, diode array, etc.


An acoustic spectrometer uses sound wave emission and advanced pattern recognition software to predict the physical Properties of powders and particulates. This type of analyser uses high frequency sounds emitted by all physical and chemical processes (particle impact, turbulent gas flow, gas evolution, fermentation, cavitation and multiphase flow). It is a non-invasive technique which is responding to dynamic event making it suitable for process control.


A mass spectrometer is an analytical instrument used to measure the mass-to-charge ratio of ions. It is most generally used to find the composition of a physical sample by generating a mass spectrum representing the masses of sample components. A wide range of industrial process control applications are therefore possible, such as the online control of solvent drying.


Particle size can be determined by light scattering (e.g. Focus Beam Reflectance Measurement) or other Methods. This type of analyser can be used to implement particle monitoring technique for in-line real-time measurement of particle size. A wide range of industrial process control applications are therefore possible such as the online control of crystallizers


Chromatography is the collective term for a family of techniques for the separation of mixtures. It involves passing a mixture dissolved in a "mobile phase" through a stationary phase, which separates the analyte to be measured from other molecules in the mixture and allows it to be isolated. Chromatography may be preparative or analytical. Preparative chromatography seeks to separate the components of a mixture for further use (and is thus a form of purification). Analytical chromatography normally operates with smaller amounts of material and seeks to measure the relative proportions of analytes in a mixture. The two are not mutually exclusive
