Flame AAS Spectrometer Machine Graphite Furnace AAS Atomic Absorption Spectrophotometer for metal elements
Product Introduction
The LR-1452G atomic absorption spectrophotometer uses deuterium lamp background technology to provide a reliable guarantee for quantitative analysis of elements. The multi-function window design with single interface reduces the difficulty of the analyst. The graphite furnace adopts the domestic advanced GFTV visual system to realize automatic sampling.
Application field
Widely used in geology, metallurgy, medicine, chemical industry, petroleum, agriculture, animal husbandry, cement, printed circuit board, environmental protection, commodity inspection and other industries.
Performance characteristics
Four lights, six lights, eight lights optional (optional high-performance element lights), automatic three-dimensional switching, energy balance, multi-lamp preheating at the same time to save waiting time, with deuterium lamp background and self-priming button background function;
Unique integrated design of flame atomizer and graphite furnace atomizer, automatic switching and manual switching dual mode;
Instrument setting conditions automatically optimize memory function, one-key scan peak search, energy balance;
Data report multi-format saving and printing output, convenient data query and comparison;
The instrument software adopts single-interface multi-function window design, which makes the operation simpler, real-time monitoring data changes, supports mainstream Windows operating system, supports remote control and calibration, Chinese/English version is optional, and has comprehensive quality control (QC) function;
Advanced and reliable multiple safety protection system, automatic detection, alarm, such as insufficient pressure, leakage, flameout and other abnormal conditions;
Domestic advanced graphite furnace GFTV visual system, CCD camera real-time monitoring of graphite furnace atomizer, extend the service life of graphite tube;
Automatic sampler system can be realized, automatic configuration of standard curve, automatic dilution, high-precision sampling;
Extendable: hydride system and combined function.
