Atomaire absorptiespectrofotometer

Atomic Absorption Spectrophotometer LX704AAS is an integrated flame/graphite furnace atomization system where the graphite system is fully automatic. They analyze the concentration of elements in a liquid sample based on energy absorbed from certain wavelength of light. They are equipped with turrets that can hold multiple lamps to reduce downtime between samples or allow for sequential analysis.

Used for testing the metal element concentration analyze in agriculture, chemical, environmental study, food, mining, and petrochemical, pharmaceutical industry.

The changeover of the integrated flame and graphite furnace atomizer is automatically controlled featuring easy operation and time saving which eliminates human labor To perform flame emission analysis, flame emission burner head can be installed for alkali metals as K, Na etc. Provided with automatic 8-lamp turret, automatic adjustment of lamp current and optimization of light beam position Parameters like Wavelength scanning, peak picking, change in spectral bandwidth, optimization of position parameters, automatic ignition and gas flow setting are done automatically The graphite furnace analysis is fully reliable and automatic, dual curve mode light-controlled temperature control technique, temperature auto-correction technique, ensures fast heating, good temperature reproducibility and high analytical sensitivity Graphite furnace with pneumatic control and pressure lock ensures constant pressure and reliable contact Automatic standard sample preparation, automatic correction of sampling probe depth, automatic tracing and correction of liquid surface height in the sample vessel, with sampling accuracy of 1% and reproducibility of 0.3% Equipped with alarm and automatic protection to fuel gas leakage, abnormal flow, insufficient air pressure and abnormal flame extinction in flame system Protection function and alarms for insufficient carrier gas and protective gas pressure, insufficient cooling rate supply and over-heating in graphite furnace system AAS analysis is made under windows operating system which is easy-to-use with fast parameter setting and optimization In order to increase the sensitivity in flame analysis, two high performance HCLs can be mounted on the lamp turret Data processing system: provided with analytical methods – Working curve auto-fitting standard addition method, automatic sensitivity correction, automatic calculation of concentration and content with windows operating system software Experiments can be repeated 1~99 times along with automatic calculation of mean value, standard deviation and relative standard deviation Equipped with multi task functions- sequential determination of multi-elements in the same sample, condition reading- with model function and result printing- measured data and final analytical report printout in excel Provided with standard RS-232 serial port connection
