Soil Fertilizer Trace Metal Content Analyzer -1

According to the requirements of the soil testing formula fertilization suggestion card, the main soil data to be tested is the content of the following substances detected by this instrument:

Potassium, iron, manganese, copper, zinc, molybdenum, calcium, magnesium, nickel, and lead (with the addition of graphite furnace, silicon and boron can also be measured)

Detection of nitrogen, phosphorus, organic matter, and sulfur content using a UV spectrophotometer

Use an acidity meter to measure the pH value

This method is the flame method, which is a relatively affordable method suitable for enterprise procurement

Introduction to fully automatic flame atomic absorption spectrophotometer: It is a precision instrument mainly used to detect the content of trace metal elements in various soil and fertilizer substances. It can detect the following elements: manganese, iron, copper, zinc, lithium, sodium, magnesium, iron, potassium, calcium, chromium (g è), cobalt, nickel, arsenic, selenium (x ī), silver, cadmium, indium, tin, antimony, platinum, gold, lead and more than 40 other elements. It is mainly detected by flame method, and the detection limit can generally be PPM level/parts per million (with a graphite furnace atomizer interface, which can be added later to make the detection limit reach PPB level or one billionth content). The computer fully controls and processes the data automatically. Automatic switching turret with eight lights, spectral bandwidth, five automatic options of 0.1, 0.2, 0.4, 1.0, and 2.0nm, automatic flow setting, automatic ignition, and automatic shutdown protection; Automatically adjust negative high voltage and lamp current; Automatic setting of optimal flame height and atomizer position, automatic control of wavelength scanning, automatic peak searching, international level full band fast scanning and positioning, automatic setting of gas flow rate, automatic selection of optimal fuel assist ratio for element analysis, real-time monitoring and measurement methods for cooling water flow, flame and abnormal pressure include 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.
