Introduction
Thank you for selecting the XDS™ Rapid Liquid
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.
The Rapid Liquid 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 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 Metrohm NIRSystems 6500-Series Liquid Analyzer was a versatile, proven design for NIR
sampling for many years. The XDS™ Rapid Liquid Analyzer benefits from the improvements in
wavelength accuracy, precision, low noise, speed, and overall performance.
