ZA-3700 is model that has furnace atomizer.
Enhanced Basic Performance : Graphite furnace analysis gets enhanced accuracy by using the specially designed cuvettes, the twin injection function which allows analysis with enhanced accuracy. The power consumption reduction by automatic turning off the hollow cathode lamp during the analysis stand by realizes energy saving.
Introduction of New Functions : The function to automatically detect bumping is introduced for graphite furnace analysis. Bumping of a sample at the drying stage, which reduces the analysis accuracy, can be automatically detected. By adding the function to suppress the memory effect and speeding up the dispensing process by the auto sampler, the analysis with better speed and accuracy is also achieved.
Easy Operation and Reliability : The polarized Zeeman correction method by the DC magnetic field, a technology of Hitachi instruments, achieves "Enhanced basic performance" and "Introduction of new functions" in both flame and furnace. While the background corrections for all elements provide the high reliability, users are strongly supported for their analysis by the software
Applications : All the 3 models of Hitachi AAS are highly sensitive thanks to Polarized Zeeman Background Correction system. Model ZA-3300 is suitable for low detection limit (ppm) and model ZA-3000 and ZA-3700 are suitable for very low detection limit (ppb). Main fields of applications are soil (Boron in particular) , water analysis, food, forensic application, geology, clinical diagnostic petroleum, etc.
Following are few of its applications-
• Flame Analysis of Cadmium in Brown Rice
• Furnace Analysis of Antimony in River Water
• Analysis of Cadmium & Lead in blood, urine and Plasma
• Analysis of metals in plants
• Analysis of Iron and Nickel in cooking oil
• High sensitivity analysis of Boron in soil
• Analysis of heavy metals in water
