R 18] [A 1] Each module is equipped with a heater (H3-H8) and a fluidic cooling (C03-C06). Temperature sensors integrated in the modules deliver the sensor signals for the heater control. Fluidic data such as flow and pressure are measured integrally outside the micro structured devices by laboratory-made flow sensors manufactured by silicon machining. The micro structured pressure sensor can tolerate up to 10 bar at 200 °C with a small dead volume of only 0.5 pi. The micro structured mass flow sensor relies on the Coriolis principle and is positioned behind the pumps in Figure 4.59 (FIC). For more detailed information about the product quality it was recommended to use optical flow cells inline with the chemical process combined with an NIR analytic or a Raman spectrometer. 

Transferability of spectral data and models in NIR spectroscopy. This subject is an issue that is pertinent to the future use of NIR for bioprocess monitoring. Pre-processing to remove baseline shifts and noise in spectra from individual machines or direct standardisation by data transformation with a representative subset can be used to calibrate across instruments [61]. 

The use of NIR for process analysis and real-time analysis of complex samples is impressive. Grains such as wheat and com can be measured with no sample preparation for protein content, water content, starch, lipids, and other components. An NIR spectrometer is now commercially available on grain harvesting machines to measure protein, moisture, and oil as the grain is being harvested. The analysis is performed in real-time, as the...

Pellenc Selective Technologies (PST), based in Prance, has 100 machines installed around the world for various types of waste separation. It has two plastics sorting systems. The Mistral uses NIR to identify aU materials in a single pass. The Sirocco uses a vision system to identify objects by location, shape, transparency, and color. Purity levels of 90 to 98 percent can be obtained output varies from 2 to 10 tonnes/hr. The systems can handle plastic, paper, metal, and multilayer aseptic packaging. Ottawa recently installed a Mistral system in their MRP. ...

Eifteen solid samples (two orientations of each) were obtained from two different machines. It was presumed that the machines were performing identically, and the main thrust of the evaluation was to determine the appropriateness of NIR to perform a rapid analysis without any sample preparation (except cutting and/or folding of the paperlike material). While the results were gratifying, the... 

Whilst the instrumentation from the established manufacturers almost invariably performs to specification, it suffers, inevitably perhaps, from being designed as general purpose. One chooses the sample holders most appropriate for one s material and similarly the operational mode, the data treatment methods etc. To various degrees one fits the material to the machine rather than the other way around. For the first two generations of NIR spectrophotometers (InfraAlyzers, Model 6500s) deployed in the wool industry this was emphatically tme. Only with the most recent developments, a joint effort between KES Analysis Inc. of New York and WRONZ, has the instrumentation been consciously designed to suit wool. An outline of the salient characteristics of the three instruments follows ...
