1: When should the deuterium lamp be replaced?
Answer: the warranty life of deuterium lamps is 1000 hours or 2000 hours; When you find that the deuterium lamp of the instrument system timer has reached the warranty period, you should replace it. From the economic point of view, if the energy signal-to-noise ratio of deuterium lamp meets the actual use requirements, it is not necessary to replace it.
2. What information should be provided when purchasing deuterium lamps?
Answer: Provide information such as the brand and model of the instrument using deuterium lamp and the serial number of the original deuterium lamp, so that the sales staff can pair up.
3: Why is the newly bought deuterium lamp different from the original one?
Answer: Because different manufacturers have different patents for designing and producing deuterium lamps, it is often encountered that the appearance of the replacement deuterium lamp is inconsistent with that of the original deuterium lamp; When purchasing deuterium lamps, be sure to indicate the brand and model of instruments that match deuterium lamps in the contract.
4. What terms should be paid attention to in the purchase contract?
Answer: In addition to indicating the matching instrument model, attention should be paid to the warranty terms; Most manufacturers’ original deuterium lamps as consumables do not have any warranty, but Hershey provides a quality guarantee of 1000 hours or 2000 hours of use and a half-year storage period.
6: How to install deuterium lamp?
Answer: There will be instructions on the replacement of deuterium lamp in the instruction manual of the instrument. Please read it in detail. At the same time, it should be noted that the glass shell of deuterium lamp cannot be touched directly by hand, please wear gloves before installation.
7: Why doesn’t the newly bought deuterium lamp light up?
Answer: At present, the user can’t directly tell whether the deuterium lamp is lit with the naked eye, but only by the energy value displayed by the instrument software. Firstly, the fault caused by instrument signal line and power supply should be eliminated, and then the fault of deuterium lamp power supply board should be eliminated.
8: Why is the newly bought deuterium lamp unstable?
A: New deuterium lamps often need to be used for 16 hours to obtain the best stability and energy; If it does not affect the use effect, please use it patiently for 16 hours before judging. At the same time, the interference caused by columns should also be eliminated.
9: Why is the energy of the newly bought deuterium lamp insufficient?
Answer: The principle is the same as A8.
10: Why does deuterium lamp suddenly go out in use?
Answer: The deuterium lamp suddenly goes out in use due to some old instruments, design defects of power supply or aging of power supply electrical performance with time. First of all, the over-limit or drastic change of mains voltage should be ruled out, and UPS should be configured when appropriate.
11: Why is the energy drop of deuterium lamp different?
Answer: The energy distribution of deuterium lamp is uneven. The energy of 200nm is about 2.5 times that of 254nm, while the energy of 200nm wavelength decreases by about 40% after 2000 hours of use, while the energy of 254nm wavelength only decreases by 25%(Longlife d2lamp).
