Using the RamanFlex 400 Series . 49

If you have a standard probe, remove the DIN connector in the socket marked LED

FIBER 1 (or LED FIBER 2 if you are removing the second FOP from your RamanFlex

400F).

If you have a triggered probe, disconnect the cable from the USB port on your PC.

Carefully remove the retained ends of the FOP by unscrewing and pulling the fiber optic

cables away from the couplers perpendicularly.
Be extremely careful when removing the FOP as you can easily damage the instrument

and the fiber optic cables.

Replace the plastic caps on the fiber ends of the FOP that have been removed from the

rear panel.

Fasten the retained screw-in caps onto the couplers on the rear panel.

Reconnect the power cables.

Acquiring Spectra with the Fiber Optic Probe

The Raman fiber optic probe has a tight focus spot that is approximately 7.5 mm away from

the lens. The focused spot enables you to pinpoint the measurement area on the sample.

Sampling Solids

Solids can be analyzed by mounting the probe on a stand and adjusting the focal spot on the

surface of the sample. Whenever possible, powders should be compacted down and thin

films of materials should be folded so that the sample covers the entire depth of field. Solids

can be analyzed in glass and plastic containers, similar to liquid samples.

NOTE: Raman spectra are measured in the visible and near-infrared region. Room lights and

sunlight will contaminate your spectra. Take care not to misinterpret room lights or

sunlight as sample features.

Sampling Liquids

Liquid samples can be analyzed by immersing the FOP in the liquid of interest or by analyzing

through the container.

WARNING

The standard FOP is not designed for immersion use. The FOP is

sealed against minor splashes; however, immersion in solvents will

cause serious damage. Ensure an immersion sleeve is in place before

immersing your FOP, see Figure 14. Please contact PerkinElmer if you

have any questions in relation to sampling using the FOP.

Immersion

The FOP can only be immersed in liquid if you have purchased an immersible fiber probe

sleeve. Do not totally submerge the probe. It is only acceptable to immerse the probe up to

1 inch from the top of the sleeve. It may be useful to focus the sample by sliding the FOP

inside the immersion sleeve to obtain the best spectrum. Note that immersion sleeves

contain either quartz or sapphire windows. These windows can yield a detailed Raman

spectrum – do not confuse this with the spectrum of the sample.
