The only guaranteed, long-lasting, high energy lamp designed specifically for Waters 2487 and 996/2996 Detectors

Waters PerformancePLUS™ long-life deuterium detector lamps were co-developed by

Waters Corporation and Hamamatsu Photonics, K.K. They are exclusively available from

Waters and cannot be sourced elsewhere. While it is possible to purchase non-Waters

lamps for your Waters detector, there are significant differences in quality and design

that can impact detector performance. A PerformancePLUS lamp from Waters represents the

modifications and testing that each lamp goes through once it is received from Hamamatsu.

UniqUeLy DeSigneD for yoUr WAT erS DeT eCTorChoosing the right lamp for your Waters detector can make a significant difference in overall

system performance. Waters PerformancePLUS Long-Life Deuterium Detector Lamps are

specifically designed for use with Waters detectors to ensure long-life, cost-effective performance.

Waters lamps offer many proprietary features not found in alternative lamps.

exclusive capacitor box design for reliable startingWaters lamp capacitors are built into the cable

so it stays cool and does not degrade over time.

This construction ensures reliable ignition of the

deuterium arc lamp for superior lifetime performance.

Array (PDA) Detectors are certified for Canadian,

European, and U.S. safety requirements with the

Waters PerformancePLUS Long-Life Deuterium

Detector Lamp included as part of the detector

design. Certification requires user-accessible wires

that experience high voltage to be double insulated.

Use of alternative lamps without certification may

compromise product safety. See Figure 2.

system resulting from use of alternative lamps is not covered under the Waters product warranty.

P reCiSion DeSign for SUPerior PerformAnC e

Waters’ lamp design continues to evolve and currently includes

these differentiating features:

n Precision alignment and tolerances applied to arc point

within the lamp housing, based on optical analysis of the

detector, to provide maximum performance. No other lamp

manufacturer has knowledge of Waters proprietary optical

design characteristics.

n Directly heated cathode for greater stability in single beam

instruments (996/2996 PDA Detector lamps).

n Consistent cathode coating for improved stability.

n Precision-machined base and proprietary design to interface

with Waters detector lamp housing for optimum performance.

n Inorganic ceramic bonding cement to minimize degradation

of lamp intensity. Alternative lamps often use epoxy adhesives

that can damage optics, resulting in very costly repairs.

See Figure 3.

Over time, the heat generated from a lamp can cause inferior bond-

ing materials to outgas, leaving a coating of contaminants on the

lamp housing window and optics bench mirror. These contaminants

can lead to premature failure of the mirrors and other optical

components due to corrosion from these contaminants interacting

with moisture and chemical vapors in the environment. See Figures

4 and 5.

rigoroUS T eST ing for reLiAbLe PerformAnC eWaters conducts extensive testing to better understand lamps

and lamp life. Waters selects a specific lamp design and then

initiates Lamp Robustness Testing, which includes life, shock,

internal lamp structure, ignition reliability, and radiant intensity

distribution testing.

Lamps also go through additional assembly and Quality Assurance

(QA) tests, including lamp alignment, intensity, and signal-to-

noise. This testing ensures an overall field failure rate of <0.1%

and an unmatchable fit for Waters instruments.

Lamp robustness TestingWaters dedicates extensive reliability resources to perform lamp

lifetime studies. In partnership with our lamp manufacturer, all

possible scenarios that can happen in your lab are tested to provide

you with optimum performance you need to succeed. Waters

development and testing has led to lamp advancements that

improve robustness and life. Degradation from shock and vibration

has been reduced due to lamp improvements. Figures 6 and 7 illus-

trate the longer lifetime, increased light intensity, and decreased

noise resulting from Waters lamps cathode improvements.

Detector Lamps have a guaranteed minimum life-

time of 2000 hours; however, data shows that these

lamps can perform up to 3000 hours.

Lamps can suffer damage when started or running.

Waters lamp design ensures that multiple lamp

strikes will not harm the lamp. As a result, you

can turn off a Waters lamp when not acquiring

data, significantly reducing the cost per sample

analyzed. Figure 8 illustrates the high sensitivity

that can be achieved with a Waters lamp.
