*Shimadzu deuterium lamp 228-34016-02 ：LAMP D2, L-6585-02 [Shimadzu part number: 228-34016-02]

Using counterfeit productsShimadzu deuterium lamp 228-34016-02Possible impacts:
Although counterfeit Shimadzu deuterium lamps are cheap, their service life is much shorter compared to Shimadzu deuterium lamps (the service life of Shimadzu deuterium lamps is 2000 hours or even more, while counterfeit deuterium lamps have only half of their service life) If the usage effect deviates from the user's expected expectations, Shimadzu Corporation does not guarantee it!Counterfeit Shimadzu deuterium lamps not only have inferior performance compared to Shimadzu pure Shimadzu lamps, but also have a certain impact on the normal use and lifespan of the instrument (such as corroding the reflector).
So please make sure to choose pure deuterium lamps from Shimadzu Corporation!

judgment* Energy:
*Set a wavelength of 200nm and check the energy of the reference cell If the energy of the instrument is below 800 under normal conditions, it is necessary to consider replacing the deuterium lamp.
*Ensure the usage environment of the instrument.
*Before analysis, turn on the detector UV light when the column balance is almost equal.
Caution: Do not frequently turn on or off the UV lamp as it may damage its lifespan. Generally, the interval time is more than three hours.

*Applicable Shimadzu liquid chromatography detector or UV model:
SPD-10A / SPD-10Avp ，SPD-20A / SPD-20AV ，SPD-15C

Its warranty period is 2000 hours, but the actual usage time is even longer than this. It is inevitable for engineers to replace deuterium lamps when using Shimadzu HPLC. What are the precautions when replacing deuterium lamps 228-34016-02, and what are the replacement steps

Precautions and replacement steps:

Step 2: Turn off the detector power and unplug the power cord

Step 3: Remove the two cap screws,

Step 4: Remove the top cover

Step 5: Unscrew the four screws of the heat sink on the light and remove the heat sink

Step 6: Disconnect the power cord plug of the deuterium lamp, loosen and remove the two screws that fix the deuterium lamp (note: the screw clamp of the long screw has been set to a specific position, do not loosen or move it).

Step 7: Remove the deuterium lamp(Note: Try to wear gloves when taking out the deuterium lamp) Do not directly touch the surface of the lamp with your hands. Place the new deuterium lamp into the lamp chamber according to the installation position (note: place the long screw behind the light emitting hole of the lamp), fix the screw, connect the power plug of the lamp, and put the power cord into the card slot

Step 8: Cover the heat sink and tighten the screws alternately to restore the top cover; Insert the power cord, turn on the power switch, and the instrument starts self checking. After the self checking of the instrument is completed, confirm that the keyboard is in the on state. Press the VP key until the screen displays "INTENANCE", and repeat the func key until the screen displays "D2 LAMP USED". Enter the number 0, press the ENTER key to confirm, reset the timer of the deuterium lamp, replace the deuterium lamp, and press the CT key twice to return to the initial interface.
