Alloy/Ore Composition Analyzer (Accurate Quantification), also known as Graphite Flame Integrated Atomic Absorption Spectrophotometer Introduction: It is a precision instrument mainly used to detect the trace/trace metal element content in various substances of alloy materials and ores. It can detect the following elements: lithium, sodium, magnesium, aluminum, silicon, potassium, calcium, chromium (g è), manganese, iron, cobalt, nickel, copper, zinc, arsenic, selenium (x ī), silver, cadmium, indium, tin, antimony, platinum, gold, lead and more. The integrated flame atomizer and graphite furnace atomizer are designed with a detection limit of PPB level (one billionth content)

SDA-100SFG (Standard Flame Graphite Furnace Type 1)Atomic absorption spectrophotometer

Introduction: It is a precision instrument mainly used to detect the content of trace/trace metal elements in various substances. It can detect more than 70 types of elements, including lead, manganese, iron, cobalt, nickel, copper, zinc, arsenic, selenium (x ī), silver, cadmium, indium, tin, antimony, platinum, gold, lithium, sodium, magnesium, aluminum, silicon, potassium, calcium, chromium (g è), etc. The integrated flame atomizer and graphite furnace atomizer are designed with a detection limit of PPB level (one billionth content), fully automatic computer control and data processing, including air acetylene flame method, graphite furnace method, hydride generator atomic absorption method, oxygen enriched air acetylene flame method; A hydride generator can be added to expand the detection range.
