Bruker® Q4 POLO

Optical Emission Spectrometry (OES)

Bruker® Q4 POLO

The Q4 POLO is the ready-to-analyze solution from day one, covering all relevant elements and wide concentration ranges. Each base metal package includes all dedicated alloy groups, calibrations, and standardization samples.


High precision analysis of solid metal samples

OES gives you an ultrafast analysis of your solid metal sample without complications. All relevant elements are simultaneously determined. Numerous innovations have been introduced in the Q4 POLO to create a spark spectrometer that is second to none. In addition to superior analytical performance for a full range of elements, the Q4 POLO enables applications previously not addressable by such compact instruments:

  • Outstanding precision, particularly on light elements
  • Excellent results in the challenging analysis of cast iron
  • Reliable analysis of nitrogen at low ppm levels in low alloyed steels
  • Analysis of oxygen in copper


BRAND® Q4 POLO analyzer at work


Iron | Steel

Pouring and processing steel requires accurate  and precise results for a wide variety of alloys. Nitrogen at trace level as well as hydrogen and oxygen content are critical to monitor.



Master the phosphorous and alkali content in aluminum with complete elemental coverage and wide calibration ranges.



Copper is the building block of many alloys. The Q4 POLO covers all the elemental analysis needs including oxygen determination.
