Product SpecificationsThe Thermo Scientific Multi-Stream

Analyzer (MSA) provides accurate, fast,

cost-effective elemental analysis of up

to 12 slurry streams. The information

provided by the MSA allows plant

operators to follow process trends in

real time, making manual or automatic

changes to the process possible.

This analyzer enables improvements

in product quality and metal recovery.

Thermo Scientific Multi-Stream Analyzer (MSA)XRF Elemental Slurry Analyzer withEnvironmentally Hardened Cross Cut Sampler

The Thermo Scientific Multi-Stream Analyzer(MSA) provides simultaneous analysis of upto 20 elements and percent solids. Elementsin the periodic table from Ca and higher canbe analyzed using the X-ray Fluorescence(XRF) technique, which is a proven androbust technology for plant environments. The MSA can measure from 3 to 12

streams. Each stream is completely separatein its own analysis tank. The probe movesfrom zone to zone. This overall designphilosophy provides the following benefits:• No additional multiplexer or de-multiplexer is required.

• Low slurry head loss of less than 1 macross the MSA, which combined with asensible location, dramatically reduces theneed for sample delivery or return pumps.

• The analysis tanks consist of a de-aerationzone, followed by an analysis zone. The standard 300-mm wide analysis tankcan accept flows up to approximately 12 m3/hr. Larger width tanks are available,which means flows up to 30 m3/hr can be analyzed, eliminating the need for primary samplers and providing enhanced sampler accuracy.

• Assay updates are fast (seven minutestotal cycle for six streams).

• The environmentally hardened cross cutmetallurgical samplers are located at theoutlet of each analysis tank for calibrationand process control samples. When usedwith full flow or a representative primarysampler (e.g., the Thermo ScientificSamStat), the MSA can collect shiftcomposite samples for metallurgicalaccounting, providing project cost savings.
