BFiber optic sampling area (optional)

CIntegrating Sphere sampling area

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.

Thermo Scientific NIR Module User Guide 7

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.
