Tilting filter

The samples had dry matter over 85% and were ground to pass through a 1 mm screen and then packed in a quartz-windowed cup. The unit was demonstrated at the 1971 Illinois State Fair. After the success of this instrument, Neotec (later Pacific Scientific, then NIR Systems, then Perstorp, then FOSS) built a rotating (tilting) filter instrument. Both instruments were dedicated, analog systems, neither of which was considered user-friendly. ... [Pg.171]

One of the important goals of NIRS analysis has been uniformity of analysis, in otherwords, a sample should obtain the same analysis value from all instruments. The first effort by instrument manufacturers was to accomplish this goal using a slope-and-bias adjustment applied to analysis values. In 1986 a second method was developed that could be used with instruments generating spectra [97], in otherwords, monochromator or tilting filter instruments. This method adjusted the... [Pg.375]
