DThermo Scientific SabIR Probe
The NIR Module provides these enhanced features:
lIntegrated design
lPush button configuration
lTwo sampling options: local (Integrating Sphere) and remote (fiber optic, optional)
lUp to two dedicated detectors
lAutomated internal reference
lStandards wheel (contains 2%, 10%, 20%, 40%, and 80% glass filters and a polystyrene sample)
The optional fiber optic sampling area can be used with the Thermo Scientific SabIR diffuse reflection
probe, or with probes from other manufactures if they have SMA connectors. For information about
additional sampling modules for the Nicolet iS50 spectrometer, contact our sales representative in
your area.
NOTICE
Be sure that all persons operating this system read the site and safety manual
first.

Operating precautions
Read these operating precautions before using the NIR Module to avoid damaging your equipment.
Precautions for the Integrating Sphere:
lDo not pour liquids directly onto the Integrating Sphere.
lDo not use harsh detergents, chemicals, or abrasives to clean the surface of the Integrating
Sphere; these can damage the finish.
lMake sure your sample materials will not react with the sapphire crystal sampling window.
lUse solvents that do not react with sapphire crystals when cleaning the sampling window.
lAvoid scraping the sampling window with samples or sample containers.
lProtect the electrical port on the surface of the Integrating Sphere. If the connector is clogged or
jammed, contact a Thermo Scientific service representative.
Precautions for fiber optic cables:
lDo not drop the cables or knock them against a hard surface.
lDo not bend the cables or tightly coil them. The radius of the coils for the SabIR Probe should be
at least 30 cm. For other fiber optic accessories, refer to their user guides.
lAvoid twisting the cables when attaching the connectors to the ports.
lDo not over-tighten or use tools to tighten the connectors when attaching the cables to the ports.
lDo not touch the end of a fiber optic cable connector or use solvents to clean it.
lKeep a protective cap on each end of the cable when it is not in use.
Precautions for the SabIR Probe:
lDo not drop the probe or knock it against a hard surface.
lDo not subject the probe to rapid or excessive changes in temperature.

Chapter 2

lWipe off spilled chemicals immediately.
lMake sure your sample material will not react with the sapphire sampling window.
lDo not allow hard materials (glass, metal, ceramic, etc.) to contact the sampling window.
lUse solvents that do not react with sapphire crystals when cleaning the sampling window.
lPower off the instrument before connecting the SabIR Probe.
lMake sure the probe is clean before you insert it into the holster.
lDo not use the probe by itself to measure liquids. When sampling liquids, use the transflectance
adapter available for the probe.
