  • 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:

    Do we need to purchase separate lamps to for analysis of different elements e.g. K, Ca, Mg, Na(?). It was not clear from the catalogue if any lamps are included with the unit, or what their price might be.
    Asked on 1/9/2013 by John H

    1 answer



      The lamps are sold separately and would need to be purchased based on the elements the customer determines to test for.
      Please see the list below for the most common lamps.
      00237DX LAMP ALUMINUM (Al)
      00253SH LAMP ANTIMONY (Sb)
      00285EN LAMP CALCIUM (Ca)
      00230TM LAMP CHROMIUM (Cr)
      00209UF LAMP COBALT (Co)
      00251IH LAMP COPPER (Cu)
      00224XI LAMP MAGNESIUM (Mg)
      00234YK LAMP MANGANESE (Mn)
      00230JD LAMP MERCURY (Hg)
      00209UH LAMP MOLYBDENUM (Mo)
      00224XL LAMP POTASSIUM (K)
      00224XG LAMP LITHIUM (Li)
      00209UI LAMP SILICONE (Si)
      00072KU LAMP STRONTIUM (Sr)
      00218RR LAMP IRON (Fe)
      00247XK LAMP LEAD (Pb)

  • Q:

    can this instrument detect Mn?
    Asked on 7/5/2012 by Vasyl Sava from Tampa, FL

    1 answer



      Yes, manganese is one of the more than 60 elements detectable with this instrument. The detection limit is 0.03mg/L.

  • Q:

    Would this work for calcium ion detection? If so in what range of concentration?
    Asked on 6/19/2012 by Anonymous

    2 answers



      This item works for calcium detection with air down to 0.2 ppm. With nitris oxide down to 0.1 ppm.
      These methods are absorbance. Flame emission concentrations are similar.

      Answered on 6/21/2012 by Rita from Customer Service


      This unit will work for calcium detection. Depending on the gas mixture used, the range is 0.01ppm to 6ppm.

  • Q:

    Can this equipment detect cerium, zirconium and aluminium?
    Asked on 6/3/2011 by Mr H from Mexico

    1 answer



      Yes, these elements can be detected by an AA spectrophotometer.

  • Q:

    Can this unit measure Zinc, Copper, Silver and Total Chrome?
    Asked on 4/15/2011 by Anonymous from West Burlington ,Iowa

    1 answer



      Certainly. These are a few of the more common elements measured and tested for by our AA Spectrophotometer.

  • Q:

    Would this instrument detect lead, cadmium, Mercury and Arsenic
    Asked on 4/4/2011 by Anonymous

    1 answer

    • Staff Reviewer


      This unit could work for all of those metals, but would need an add on accessory to determine mercury. The part number of the mercury would depend on the levels you were looking to detect. Please contact our technical application specialists by phone or email for additional assistance (contact information can be found in the "contact us" section on the web page).
