Metrohm NIRS XDS RapidContent Analyzer - Manual (Page 8)

The Rapid Content Analyzer also offers variable spot size, to focus energy on small samples. This
feature is standard on the Solids Module.
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.
Vision Software™ offers an easy user interface, using the familiar interface provided with previous
generations of NIR instrumentation. All functions required to perform identification, qualification, and
quantitation are provided, with easy tools for interpretation of results. Vision offers full instrument
diagnostics, with built-in acceptance specification tables for all tests. Vision stores all results in a
diagnostic database for later lookup, with control chart views of results tracked over time.
The menu-driven, validated Vision Software package meets all requirements of CFR 21 Part 11,
covering Electronic Records and Signatures. Vision comes with a full manual for operation and theory
of operation, with complete instructions for analytical development.
The XDS Analyzer provides 0.5nm data points, and uses several innovative methods to assure
wavelength accuracy and repeatability. Wavelength positions are traceable to NIST SRM-1920a.
Because SRM-1920a does not have certified wavelengths above 2000 nm, an additional wavelength
absorber is included in the calibration standard, to provide stable wavelengths beyond 2000 nm.
These additional wavelengths have been independently measured on calibrated instrumentation to
ascertain the wavelength positions used.
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
Green when stable operating temperature is reached
Green when module is properly attached
Instrument communication is through RJ-45 network connections, which eliminates issues involved
with long runs of RS-232 cable. An Internet Protocol (IP) address is dynamically requested upon
connection. This address may be permanently installed, if required for network purposes. The RJ-45
