A METHOD OF EFFECTING NIR-ANALYSES OF SUCCESSIVE MATERIAL SAMPLES, AND A SYSTEM FOR CARRYING OUT THE METHOD

摘要

the analysis by the reflection in the near infrared (nir) in a sample of the material is performed on a very small sample in a test basin placed in close contact with the special unit, which is a reflection of the radiation from the surface of the sample. and, therefore, provides information on the contents of the components of interest.such as water and protein. under normal laboratory conditions, we need to clean up the toilet, carefully test and the optical unit in a series of operations for obtaining reliable results.with the present invention, the method is used for analysis of continuous fully automatic of successive samples, through the use of a test chamber (6) which is built together with the optical unit (12) and which is open in the direction of the unit. e through a side opening (26) is limited.the test chamber (6) has a volume greater than the known test cells, thereby maintaining the pollution caused by the remnants of the sample in a low acceptable, without it being necessary to complete each time to clean house for testing.a particularly critical area is formed by the material from the area just after the optical unit (12, 64) and remains at that location should be removed.the present invention provides a complete removal of the deposits of these are due to the fact that between the side opening (26) of the test chamber and the optical unit (12, 64) is disposed on a transparent thin film (20) which is separated between the successive operations.advance in order to allow the removal of the zone of the film used, and the movement of the new area of film entirely in the critical zone.
