ii.Atomic system

 (Cu) characteristic concentration:1.0ug/ml,  absorbance: >0.280Abs

 (Cu) detection limit: 0.002μg/ml

 Burner: 100mm titanium metal, air premixed

 Precision: RSD≤0.5%

 Sprayer: high efficiency glass atomizer, all plastics, SS atomizer

 Atomizing chamber: corrosion resistant material

Position adjustment: flame burner optimum height, front and rear position adjustable, complete the transfer between the flame and the hydride in one minute

Safety: with many kinds of automatic protection, acetylene gas leakage alarm, closed system

With flameout, light control automatic gas protection function, more secure and reliable in laboratory.

 

iii.Analytic method

Measurement method: air-acetylene flame method, hydride generator atomic absorption method, oxygen-air acetylene flame method.

Concentration calculation: standard curve method (1-3 times curve), auto fitting, standard addition method.

 Repetition survey frequency: 1-20times, calculate average value, display standard deviation and relative standard deviation.

Printing result: parameters print, data result print, graph print, summary report.

Software: Windows 98/2000/XP.

 Data output mode: instantaneous value, integral value, peak, peak area.
