AA-7090 atomic absorption spectrophotometer Introduction
AA-7090 atomic absorption spectrophotometer adopts a new type of atomic absorption spectrometer with horizontal heating and longitudinal Zeeman background correction and variable magnetic field strength. The AA-7090 atomic absorption spectrophotometer has improved the background performance of the graphite furnace button, which can meet the increasingly urgent element content analysis requirements of complex matrix samples with severe background interference in various fields such as food and environment. Features
The horizontal heating graphite furnace technology ensures the high efficiency and uniformity of sample atomization;
Longitudinal communication Zeeman and deuterium lamp two background correction methods, users can choose different background correction methods according to specific samples;
Adjustable magnetic field strength (0.6 ~ 1.1 Tesla in 0.1 Tesla steps) to ensure sensitivity and accuracy;
8-lamp automatic lamp holder with automatic alignment function;
Coded lamp recognition technology can recognize both hollow cathode lamps and super lamps;
Super lamp power supply, while ensuring high sensitivity, consume less power and generate less heat;
The combustion head is automatically raised and lowered;
Graphite furnace visual system, the operator can realize the whole process of observing the sample from just being injected into atomization, and in this process, the parameters of sample dissolution, drying and ashing can be set correctly, so as to obtain Reproduced results;
Graphite furnace gas-saving mode, improve the effective utilization of protective gas, can double the gas use time, reduce the cost of the instrument;
Double gas circuit technology;
Double background correction mode, users can choose different background correction methods according to specific samples.
