Binsong L8932 deuterium lamp

Binsong L8932 deuterium lampPrecautions for use

1. Contamination of deuterium lamp cover: Do not directly touch the deuterium lamp cover with your hands, as oily substances on your hands can hinder the emission of light from the deuterium lamp source, resulting in low readings. Once accidentally in direct contact with the deuterium lamp, isopropanol can be used to clean the deuterium lamp before installation.

2. Switching frequency of deuterium lamp: Frequent switching and prolonged lighting can affect the lifespan of the lamp. Generally, after the deuterium lamp is lit, it needs to30A stable time of about minutes. Special attention should be paid to wait for the deuterium lamp to cool down before turning it back on. Because if the deuterium lamp is turned on in an uncooled state, it is likely to cause the overall structure of the filament to burn out.

3. Avoid severe physical vibrations: If the light is on, it is likely to damage or even break the filament. Because when the deuterium lamp is lit, its temperature is2700KAt this point, the filament is almost liquid. ）

4. Signal for replaceable deuterium lamp:

a.The blue light cannot be seen at the edge of the lamp casing. (Visible to the naked eye);

b.The quartz jacket turns black. (Check, cool and replace when the light is turned off);

c.Non linear phenomena that have never appeared in previous analysis methods (the absorption rate of light is not linear);

d. Under normal settings, baseline drift is severe;

e.positiveThere is no peak observed during regular injection.

in order to obtainBinsong L8932 deuterium lampHigh stability and long service life require attention to operating conditions, including lamp operating temperature. The temperature of the bulb wall changes with the ambient temperature. The wall temperature of the bulb also varies depending on the type of bulb, filament voltage, and installation method.HamamatsuL2D2 lamp is designed for operation when used indoorsZGood lamp temperature. However, in order to meet the working temperature range over a long period of time, if the lamp is used at a temperature exceeding the allowable working temperature, the cathode temperature will increase and cause cathode evaporation. On the other hand, if the lamp is used at a temperature lower than the allowable temperature at its operating temperature, the gas pressure inside the bulb decreases and the kinetic energy of ions increases. This leads to splashing of cathode electron emitting materials. In both cases, the gas inside the bulb will quickly dissipate.This reduces the stability and radiation intensity of the lamp, greatly shortening its service life.
