This is an aftermarket part, not an original manufacturer part. Instrument names and part numbers identify what it fits and replaces; they remain the trademarks of their owners. The manufacturer, country of origin, rated life and warranty are stated in the quote, before you decide anything. If you need the OEM part, say so and I will quote that instead.

Deuterium lamp for Selekt detectors

Aftermarket deuterium lamp for Selekt detectors. On a flash system a failing lamp costs you material rather than just signal, because the detector is what triggers fraction collection. A weak baseline means peaks that never reach the collection threshold, and product that goes to waste while the run looks like it worked. That is a more expensive failure than a noisy analytical baseline, and it is easy to mistake for a threshold that needs adjusting. If collection has started missing peaks you know are there, check the lamp energy before you touch the threshold.

Type: Deuterium
Fits: Selekt

Before you order: if the instrument is misbehaving, tell me the symptom, not the part number. Lamps and seals get replaced for problems they did not cause. The first look costs nothing, and if this part is not the fix, I will say so.

Deuterium lamp for Interchim detectors

Deuterium lamp for Interchim detectors, cross-referenced to SD1191-01J. These sit on flash purification systems, so the lamp is on for the whole collection run rather than for a few minutes per injection and hours accumulate much faster than the number of purifications suggests. On a flash system a weak lamp costs material rather than data: the detector triggers fraction collection, so peaks that fail to reach the threshold go to waste while the run appears to have worked.

Deuterium lamp for Waters 2489 and 2998 detectors

Aftermarket deuterium lamp for the Waters 2489 and 2998, cross-referenced to 201000281. The 2489 runs at set wavelengths and the 2998 reads the full spectrum, and the same lamp serves both. On either detector, deuterium output falls fastest in the deep UV, so a method running at 210 nm loses sensitivity long before one running at 254 nm does. This detector expects a lamp carrying an RFID tag. The chip is listed in the specification above, and it is worth confirming before you order, because a chipless lamp can be refused by the instrument.

Deuterium lamp for Waters 996 and 2996 PDA detectors

Deuterium lamp for the Waters 996 and 2996 photodiode array, cross-referenced to WAT052586. A PDA reads the whole spectrum at once, which is what makes lamp ageing visible earlier here than on a fixed wavelength detector: pull up a 3D plot and you can watch the deep UV end go noisy while 254 nm still looks fine. Use that before ordering. If the noise is flat across the whole spectrum rather than worst below 250 nm, the lamp is not what is wrong.

Power supply for Waters 2489 HB lamp

Power supply for the Waters 2489 high brightness lamp, cross-referenced to 700002785. This is the part to consider when a new lamp has not fixed the fault. The high brightness lamp needs its supply to strike and hold it, and a failing supply gives you a lamp that will not light, or one that lights and then goes unstable, both of which look identical to a dead lamp from the front panel. If you have already fitted a new lamp and nothing changed, order this rather than a second lamp.
