Problems solved by technology

[0058] All of the methods described above attempt to overcome some of the problems associated with the use of spectrophotometers, but all of these methods still suffer from serious problems because they require individual calibration and most of them are not suitable for applications that require real-time results
[0059] Even those methods that provide some form of real-time analytical capability have inherent calibration issues

Embodiment Construction

[0097] figure 1 is a schematic diagram depicting a partial network (generally indicated by arrow 1 ) relevant to an aspect of the present invention.

[0098] The network (1) includes many near-infrared spectrophotometers (2), none of which have data processing capabilities.

[0099] The spectrophotometer (2) transmits its data to the central processing unit (3) by hard wiring. The central processing unit (3) has a set of calibration values ​​which are transferable and can be used for the relevant data from each spectrophotometer (2). In some embodiments of the invention, the central processing unit (3) may also have individual calibration values ​​associated with each spectrophotometer (2).

[0100] When the central processing unit (3) has processed the data, it transmits it to the output device (4). In this embodiment, the output device (4) may be a control system capable of manipulating the physical processes of the material analyzed by the spectrophotometer (2) based on ...

Abstract

This invention relates to a method of processing data from at least one spectrophotometer (2) characterised by the steps of transferring the data from the spectrophotometer to a central processing unit (3), and processing the data at the central processing unit, and transferring the processed data to an output device (4).

Description

technical field [0001] The invention relates to a treatment method. [0002] In particular, the invention relates to a method of processing data from a spectrophotometer. The invention finds particular application in processing data from near-infrared spectrophotometers, but it will be appreciated that the invention can be applied to other types of spectrophotometers. Background technique [0003] Near infrared spectrophotometry (NIRS) is widely used in industry to analyze the composition of various materials. These NIRS are especially useful in determining the contamination of certain materials, if present, and can provide analytical results within minutes. In contrast, chemical tests often take several days to provide analytical results, after which time it may be too late to prevent contamination or other unsuitable materials from being used where they are not intended. NIRS is also more reliable and faster to calibrate than standard research spectrophotometers. [00...
