Introduction
Thank you for selecting the XDS™ Smart Probe
Analyzer, manufactured by FOSS. This instrument is
the third generation in a series of instruments
designed for precision NIR measurement,
characterization of organic materials, and
qualification of known materials to quality
parameters.
The XDS™ is designed for stable operation in harsh
environments, while still providing the precision and
accuracy users have come to expect of FOSS
instruments.
Standard fiber bundle lengths are 2-meter and 3-
meter. The 3-meter fiber bundle is shown here.
The Smart Probe Analyzer uses a proven monochromator design, employing a digitally-controlled
dispersive grating, along with sensitive detection devices and state-of-the-art circuitry to enhance
signal output and minimize any extraneous noise that might influence performance. The XDS™ uses
various patented algorithms to provide superior accuracy and transferability between like
instruments.
This instrument uses near-infrared (NIR) spectral energy to illuminate the sample. By measuring the
energy reflected off (or passing through) the sample, chemical information and composition may be
determined. This information may be used for quantification of constituents, or for comparison to a
library of known materials, providing identification and qualification of materials.
The Smart Probe Analyzer has been a versatile, proven design for NIR sampling for many years. As an
XDS™ instrument, the Smart Probe benefits from the improvements in wavelength accuracy,
precision, low noise, speed, and overall performance.
A panel of 6 LED indicators provides information to the user on these functions:
Icon Status
Green when power is ON
Amber when connected to network or direct
connection
Green when instrument lamp is ON
Red when scanning reference or sample
