Q4 POLO - Little Space, Mighty Performance

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

Just as impressive as the results achieved by the Q4 POLO is its incredible long-term stability. The absence of thermal- and contamination-based drifts reduces the need for cleaning and recalibrations, leading to stable results around the clock.

The new 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. At the same time, the Q4 POLO provides high uptime, low maintenance, and hassle-free operation.

Key Benefits

  • MultiVision™ optics with electromagnetic light junction covering the full elemental range with superior performance and small footprint
  • AAC™ and ArgonShield™ result in incredible long-term stability without increasing argon gas consumption
  • The new active sensing SmartSpark™ source is fully digital and equipped with detection of non-energetic discharges for increased precision and long-term stability
  • ELEMENTAL.SUITE delivers highest functionality combined with ease-of-use for information @ your fingertips.

Why do I need spark-OES?

OES gives you an ultrafast analysis of your solid metal sample without complications. All relevant elements are simultaniously determined.

What is your analytical challenge?

Iron & Steel

Processing steel requires precise and accurate results on incoming and outgoing materials over a wide variety of alloys, incl. N at trace level.


Mastering the phosophorous and alkali content in aluminum.


Copper is the building block of many alloy types. The Q4 POLO covers them all including oxygen determination.
