Model: Xenon Lamp Replacement

Type: User guide

This guide describes how to replace the xenon lamp light source of the Surveyor™ FL Plus

Detector.

As the lamp reaches the end of its lifespan, the light output decreases, resulting in decreased

sensitivity. You can track the sensitivity of the detector with the Maintenance for FL Plus

application program. Replace the lamp when it reaches the end of its lifespan, approximately 500

hours of use.

Before you install or replace the xenon lamp, view the training video provided with the

fluorescence detector.

Because the xenon lamp has the potential to explode, wear a face shield and gloves, in addition to

your standard safety glasses and laboratory coat, when you replace the xenon lamp.

The face shield must meet ANSI Z87.1, CSA Z93.3, or the equivalent.

Thermo Fisher Scientific recommends N-DEX™ PLUS 8005 gloves,

manufactured by Best Manufacturing Company. To order these gloves from

Thermo Fisher Scientific, use the following part numbers:

•P/N 00301-01-00005 (size small)

•P/N 00301-01-00006 (size large)

Store this additional personal protective equipment near the FL detector (see Figure 1).

Xenon Lamp Replacement Guide

CAUTION Because the xenon gas inside the glass bulb is under extremely high

pressure, the xenon lamp can explode.

To remove the xenon lamp housing from the detector housing

1. Turn off the power, and unplug the detector from line power.

2. Allow the lamp to cool for a minimum of two hours.

3. Loosen the retaining screw that secures the flow cell unit to the detector, and then pull the flow

cell unit forward to remove it from the detector. Place the flow cell unit on a lint-free cloth.

4. Using a #2 Phillips screwdriver, remove the five screws that secure the stainless steel plate to the

detector chassis (see Figure 2).

Removing the Xenon Lamp Housing from the Detector

CAUTION For safety reasons, disconnect the power cord before removing the

stainless steel plate from the front panel of the FL detector.

CAUTION The xenon lamp generates enough heat to raise the temperature of

the surrounding metal surfaces to a dangerous level. Before you remove the

xenon lamp housing from the detector, allow the xenon lamp to cool for at

least two hours.

To remove the xenon lamp from the xenon lamp housing

1. Place the xenon lamp housing on its side.

2. Holding the metal fixture at the top of the xenon lamp, unscrew the anode nut, and then slide

the anode terminal of the lamp backward out of the ceramic plate (see Figure 5).

Removing the Xenon Lamp from the Xenon Lamp Housing

IMPORTANT Do not touch the mirror inside the xenon lamp housing. If you accidentally

touch the mirror, clean it with a lint-free cloth soaked in high-grade isopropyl alcohol.

3. Holding the metal fixture at the bottom of the xenon lamp, unscrew the cathode nut, and then

pull the cathode terminal out of the cathode lead plate (see Figure 6).

To connect the xenon lamp to the xenon lamp housing

1. Place the xenon lamp housing on its side.

2. Remove the xenon lamp from its packaging.

3. Remove the nuts from the ends of the lamp.

4. Secure the xenon lamp to the xenon lamp housing as follows (see Figure 7):

a. Holding the metal fixture at the bottom of the lamp, insert the cathode terminal into the

hole in the cathode lead plate, and then screw one of the nuts onto the cathode terminal.

b. Holding the metal fixture at the top of the lamp, insert the anode terminal into the hole in

the ceramic plate, and then screw the other nut onto the anode terminal.

Installing the Xenon Lamp

IMPORTANT Dust and fingerprints on the glass bulb reduce the light output of the

xenon lamp. If necessary, clean the glass bulb with a lint-free cloth soaked in high-grade

isopropyl alcohol.

Figure 7. Connecting the xenon lamp to the xenon lamp housing

5. Ensure that the protrusion on the light bulb faces towards the front of the xenon lamp housing

and that the metal wire is next to the protrusion (see Figure 7).

To reinstall the xenon lamp housing and the flow cell unit

1. Slide the xenon lamp housing into the chassis (see Figure 3).

2. Insert the xenon lamp housing plug into the receptacle in the detector chassis.

3. Insert the thumbscrew through the hole in the grip of the xenon lamp housing, and then hand

tighten the thumbscrew to secure the lamp housing to the chassis.

4. Using the five screws you removed in step 4 on page 2, secure the stainless steel plate to the

front panel of the detector.

5. Reinstall the flow cell unit and tighten its retaining screw.

After you connect the FL detector to line power, refer to the Surveyor FL Plus Detector Hardware

Manual for instructions on aligning the xenon lamp.

CAUTION Take care to install the xenon lamp in the correct orientation. If

you reverse the polarity of the terminals, turning on the power to the

detector does not trigger the lamp and can damage the lamp cathode.

To dispose of the used xenon lamp

1. Wearing a face shield and gloves, completely wrap the xenon lamp in a heavy duty towel, such

that no portion of the lamp is exposed (see Figure 8).

2. To burst its glass bulb, hit the wrapped xenon lamp with a hammer or an equivalent heavy

object.

3. Dispose of the broken glass in an appropriate waste container.

After you complete the xenon lamp replacement procedure, return the face shield to the

appropriate storage location and return this booklet to the pocket in the left door of the detector.

Disposing of the Xenon Lamp

1. Wrap the xenon lamp in a heavy duty towel.

2. Hit the wrapped xenon lamp with a hammer. 3. Dispose of the broken glass in an appropriate

waste container.
