SDA-100SF standard single flame atomic absorption spectrophotometer,

Introduction to Atomic Absorption Spectrophotometer: This model is an improved and upgraded version of the original version, mainly used as a precision instrument for detecting the content of trace metal elements in various substances. It can detect more than 40 elements including manganese, iron, copper, zinc, lithium, sodium, magnesium, iron, potassium, calcium, chromium, cobalt, nickel, arsenic, selenium, silver, cadmium, indium, tin, antimony, platinum, gold, lead, etc. It is mainly detected by flame method, and the detection limit can generally be PPM level (parts per million content)
