Product Description:

What is Atomic Absorption Spectrophotometer?

Atomic absorption spectrometer(also known as atomic absorption spectrophotometer), analyzes metal elements according to the effect of atomic vapor in the ground state of substances on the absorption of characteristic radiation. It can determine trace or trace elements sensitively and reliably.

Atomic absorption spectrophotometer generally consists of four major parts:light source, sample atomizer(Flame atomizer /graphite furnace atomizer), monochromator and data processing system (including photoelectric converter and corresponding detection device).

What elements can be detected by atomic absorption spectrometer and detection method?

1.Atomic absorption flame method: atomic absorption flame method (air-acetylene) can detect PPM grade.

lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), rhodium (Rh), palladium (Pb), platinum (Pt), gold (Au), copper (Cu), silver (Ag), zinc (z η), Germanium (Ge), cadmium (d), indium (n), gallium (Ga), lead (Pb), arsenic (As), bismuth (B), selenium (Se), antimony (Sb), ruthenium (Ru), etc.

2.Atomic absorption hydride method:Atomic absorption hydride method can detect trace elements with low melting point (PPb level).

Determination: arsenic (As), selenium (se), antimony (Sb), bismuth (Bi), lead (Pb), tin (Sn), tellurium (Te), germanium (Ge), mercury (Hg), etc.

3.Atomic absorption graphite furnace method:The element detected by atomic absorption graphite furnace method has less sample injection and high sensitivity (PPb level).

Silver (Ag), aluminum (A), arsenic (As), gold (Au), barium (Ba), beryllium (Be), bismuth (B), calcium (Ca), cadmium (Cd), cerium (Ce), cobalt (Co), cesium (Cs), copper (Cu), dysprosium (Dy), erbium (Er), europium (Eu), iron (Fe), gallium (Ga), holmium (Ho), indium (hn), potassium (K), lanthanum (La), lithium (Li), magnesium (Mg), manganese (Mn), molybdenum (Mo), sodium (Na), nickel (Ni), platinum (Pt), osmium (Os), lead (Pb), palladium (Pd), praseodymium (Pr), hafnium (H), rubidium (Rb), rhodium (Ph), ruthenium (Ru), antimony (Sb), scandium (Sc), selenium (Se), samarium (Sm), tin (Sn), zirconium (zr), tellurium (Te), titanium (T), alum (V), zinc (Zn), silicon (si), etc
