AA-6300 Atomic Absorption Spectrophotometer

High-throughput Dynamic Beam Management System

• Ensures long-term stability with low noise level
  
• Provides the highest level of sensitivity for trace-level analysis (Direct determination -
  
• Flame: Pb, 0.1ppm; Furnace: Pb, 0.3ppb)

Dual-Detector System with Dual Background-Correction Function

• Ensures maximum sensitivity and accurate background correction at all wavelengths
  
• Easy selection process provides optimum method for meeting analysis objectives

Burner Height and Gas Flow Rates are Automatically Set for Each Element and Matrix

• Ensures maximum sensitivity and superior detection limits
  
• Enables continuous measurement

WizAArd Software - A Match for this Electronic Records Era
The newly developed "WizAArd" (Windows-based 32bit) software is much easier to understand and use, with a parameter editing function that enables conditions to be changed rapidly and comprehensive data processing functions. It provides a high level of electronic records security functions for compliance purposes:

• Manage user login ID names and passwords
  
• Manage authority restrictions according to user level
  
• Electronic signatures and audit trail functions have been equipped as standard
  
• QA/QC functionality as required by the U.S. Environmental Protection Agency (EPA) has been improved
  
• Hardware validation software is also standard.

Switch Smoothly Between Flame and Furnace - Without Tools

Simply remove the burner head and put in place the furnace section.

A single autosampler can be used for both flame and furnace, which negates the need to prepare the autosampler for each analysis method.

Comprehensive Flame Analysis

Highly Sensitive and Stable Flame Analysis
The High-Throughput Dynamic Beam Manager System developed uniquely for the AA-6300 automatically sets the photometric system to optical double beam for flame measurement, and to electrical double beam for furnace measurement. Furthermore, the optical system has been designed to produce its maximum performance in each of the measurement methods through the optimal adjustment of the light beam, high-speed operation digital filter, and employment of optical components.

Flame Analysis under Optimal Conditions at All Times
The AA-6300 conducts measurements by automatically setting the optimal conditions for not just the gas flow rates, but also for the burner height for each element at all times.

Detailed methods - including the burner height - can be saved in files as measurement conditions, making it possible for anyone to conduct optimal measurements at any time.

Safe Flame Measurement
The following safety mechanisms have been incorporated.

• Safe ignition/extinction sequence
  
• Flashback prevention through the gas pressure monitor
  
• Prevention of raw gas release when the flame dies out
  
• Burner misuse prevention
  
• Automatic flame extinction in a power failure
  
• Safety inspection support provided by software, and a self-diagnostics function that determines whether the system safety mechanisms are in working order

Comprehensive Furnace Analysis

Highly Sensitive and Stable Furnace Measurement
Unique control of the gas flow inside the graphite tube at atomization (Patent 2067563) ensures high sensitivity measurement - among the best in the world. Combining a high-sensitivity optical sensor with a digital temperature control system enables temperature control with a high degree of precision over the entire temperature region from drying to atomization. By employing the electronic controller, the flow rate of the inner gas can be controlled precisely in 0.01L/Min units.

Furnace Analysis under Optimal Conditions at All Times
With a sophisticated autosampler, a maximum of 4 reagents (such as the diluent, standard solution, sample, matrix modifier) can at first be mixed and then injected (without mixing as well).

The system can be set to automatically dilute and repeat the measurement if the calibration curve concentration is exceeded.

Safe Furnace Mechanisms

• Cooling water flow rate monitor
  
• (Ar) gas pressure monitor
  
• Over-current prevention device (double checked with the breaker and the optical sensor)
  
• Furnace block cooling check
