  • A library with methods of analysis for over 60 elements
  • Software preloaded with operation conditions
  • Stable optical system for high sample throughput
Low detection limits and simple, rapid testing methods make these sensitive atomic absorption (AA) spectrophotometers ideal for environmental testing, toxicology, and quality control labs. Selectable bandwidth complies with many EPA methods. Convenient controls enable optional adjustment of all parameters - lamp and burner alignments, gas flows, light output levels, andoperational analysis modes. Prominent display reads absorption, concentration or emission values.
Durability and safety add value to these sensitive instruments. The titanium burner head is enclosed in a high-density polyethylene (HDPE) premic chamber to prevent corrosion. The burner safety interlock system prevents start-up if improper gas is connected or if the burner is not connected.
This rugged, easy-to-use unit is perfect for repetitive analysis. The combination of the stable beam optical system and a higher sensitivity allows for fast accurate analysis. The increased burner sensitivity makes it ideal for testing far-UV elements, such as arsenic and selenium. Deuterium background correction on 28750-10 and 28750-15 compensates for organics present in sample matrix.
This microprocessor unit on 28750-10 and 28750-15 has powerful software tools for analysis and reporting. Output on 28750-35 is RS-232 provided without report generation software.
What's included: air/acetylene burner, methods library, software package, and a 6-foot cord with a 3-prong plug.

  • Q:

    Does this AAS need to be vented?
    Asked on 3/10/2016 by drn from Buffalo, New York

    1 answer

    • STAFF EXPERT

      A:

      For best performance, this unit should be located in a well-ventilated room, free of dust, draughts, and corrosive fumes and vapors. Because it must be vented through an exhaust duct, it is best to locate the instrument near an external wall, or close to other duct lines that are used for similar purposes. It is sometimes possible to tie the exhaust vent into a laboratory fume hood exhaust line. A backflow preventer should be installed between the unit exhaust line and the fume hood line to prevent cross-contamination.

  • Q:

    Hi.
    We have an Electro Plating process, and have a need to determine if we are within our legal discharge consent level of 0.5mg/L.
    Would this apparatus enable us to read the silver content of our silver plating solution in miligrams.
