Bruker has launched the new Q4 POLO, a compact spark optical emission spectrometer. In addition to the large element range from lithium to bismuth, the Q4 POLO enables applications previously not addressable by such compact instruments: high 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; and analysis of oxygen in copper. The Q4 POLO also has long-term stability: the absence of thermal- and contamination-based drifts reduces the need for cleaning and recalibrations. Bruker’s patented Automatic Ambient Compensation (AAC™) ensures that the optical system keeps its focus by eliminating thermal drift. The new ArgonShield™ prevents contamination of the optical window during measurements. The active sensing digital SmartSpark™ source further improves analytical precision and long-term stability, enabling shorter measurement times. The coverage of the full elemental range is achieved by a unique electromagnetic light junction as core component of the MultiVision™ optics.
