AAS Au, Ag, As Element hollow cathode lamp

Hollow cathode lamps with all elements

Three type: PE sepcial , PE older model, normally instrument,.

Introduction:

Every lamp is designed for use with and tested on our spectrometers to assure compatibility and the highest performance. We offer a wide range of single-element and multi-element HCLs, which are ideal for determining most elements by atomic absorption spectroscopy. To prolong the life of a Hollow Cathode Lamp (HCL), we produce lamps with larger internal volume so that a greater supply of fill gas at optimum pressure is available. The larger the lamp, the greater the inert gas volume - and the longer the lamp lifetime. 

Features:

1. Start voltage: less than or equal to 350 V.

2. Background: the background strength near main analysis line is less than 1% of analysis strength.

3. Preheat time:less than 30 min, generally between 5 and 15 min.

4. Stability:the baseline drift is less than 1% within 300110 for the copper lamp and with 5^11 for other element lamps.

5. Noise: less than 0.3%

6. Service life: no less than 5000 mA h for common element lamp and 5000 mA h for fusible and fugitive element lamps.

7. Maximum operating current: generally between 10 and 20 mA.
