Gas dual temperature control inside and outside, 20 order linear or
nonlinear heating, to ensure that the measured elements has the
highest sensitivity; furnaceenriched up to 20 times, the
longitudinal optically monitoring the graphite tube wall
temperature, maximum temperature to 3000 degrees centigrade.
High technology index
AA-1800 atomic absorption spectrophotometer elements
testsensitivity meet international best level,sensitivity of less
than or equal to0.015μg/mL/1%; baseline drift is less than
0.003Abs/30m, the stability is better than 0.005Abs/4h
Background correction system
Using deuterium hollow cathode lamp advanced and self absorption
background deduction of background correction, to eliminate the
interference of molecular absorption of low content determination,
reducing the noise emission of deuterium lampand prolongs the
service life, has excellent stability. Deuterium lamp background
signalfor 1A,
