AFS lamp KY-AF
In order to gain good sensitivity in detection with atomic fluorescence spectrophotometer, the signal-to-noise ratio is
dependent on following three aspects:
Fluorescent lamp of instrument light source Atomization sampling system Instrument acquisition and processing system
Element As ï¹’ Bi ï¹’ Cd ï¹’ Ge ï¹’ Hg ï¹’ Pb ï¹’ Au ï¹’ Cr and Cu
Element Sb ï¹’ Se ï¹’ Sn ï¹’ Te ï¹’ Zn ï¹’ Ni ï¹’ Fe ï¹’ Co and Ag
ï¹’ Hydride process Others adopt flame method
Fluorescent lamp stability:
JJG standard:<2% (preheat for 30min and record for 30min)
Manufacturing standard: ≤ 1.5% (preheat for 30min, record 30min)
Energy of fluorescent lamp:
Hg:Standard solution 1ng, reading value of instrument>1500
As:Standard solution 10ng, reading value of instrument > 2000
AFS lamp KY-AF-A
Stability of AFS lamp：
≤ 1.5% (preheat for 30min and record for 30min)
Emitted energy of AFS lamp:
Hg standard solution
1Reading value of 1ng instrument >1500
As standard solution
Reading value of 10ng instrument >2000
Concentricity of ASF light：
When the light rotates 360 ° , the shift to reading
value of instrument is <15%
