The Thermo Scientific MEP-300 Multi-Element Probe provides continuous in steam analysis without the need for liquid nitrogen. When used as part of the Thermo Scientific AnSat, Duplex AnStat or MSA, it allows plant operators to follow and respond to process trends in real time.

The MEP-300 has been developed to replace both the MEP and MEP-200 liquid nitrogen cooled X-ray Florescence immersion probes used in the AnStat, Duplex AnStat and MSA. It may also be used to replace Single Element Probe (SEP) analyzers in Iron, Copper, Zinc, Lead and other applications.

The MEP-300 contains a thermo-electrically cooled, energy dispersive X-ray detector to

deliver outstanding performance across a wide range of elements.

The MEP-300 uses an advanced Silicon Drift Detector (SDD) which is both compact, rugged and does not require cryogenic temperatures. The detector resolution and counting rates offer quality analytical performance, resulting in the MEP-300 being ideal as an upgrade to your existing systems.

The advantages include increased safety (eliminating hazardous material), a decrease in utility costs (non purchase of LN2) and a manpower saving (as there is no need to service with LN2).

All configurations contain:

• MEP-300 Multi-element Probe

• MEP-300 Controller Enclosure

• WinISA software providing configuration, operation, maintenance, calibration and communications by Ethernet TCP/IP

Common benefits of the upgrade

• The MEP-300 can use the existing isotope to reduce the cost of an upgrade and maintain the radiation product license.

• The MEP-300 electronics replace the earlier analogue MEP or the more recent digital MEP-200 electronics.

• The MEP-300 Controller (with software upgrades) replaces earlier controller versions - extending the service life of the equipment.

• The MEP-300 (with an integral retractable source for greater protection) can measure many elements and levels of % solids - which are communicated to a central server.

Why should I upgrade? Reduce costs, increased safety and greater efficiency

What product can be upgraded? AnStat, Duplex AnStat and MSA (4.0 onwards)

What are the steps in the upgrade proposal process? • Contact your local Thermo Scientific sales or service • Complete site questionnaire • Site visit and equipment audit • Receive proposal

What do I have to prepare for? A detailed list of site preparation tasks will be provided with the upgrade proposal.

After accepting the proposal a Thermo Scientific service engineer will visit and install the upgrade, provide training and assist with calibration. In some cases LAN and instrument air infrastructure will need to be augmented.

Will I have to recalibrate? Yes, you will need to allow for a new calibration of the equipment.

Can I replace my SEP with the MEP-300? Yes, several single element probes (SEP) can be replaced with a single MEP-300, therefore only requiring one isotope.

If I replace a SEP what will I need? The MEP-300 configuration will fully replace the SEP; however you will require a hoist.

Will there be any impact to my accuracy? No, the MEP-300 will provide comparable accuracy.

Can I use my existing source? In most cases it can be transferred to the MEP-300 during the upgrade; however in some cases the source may need to be replenished.

How is the radioactive materials license affected? You will need to notify your local regulatory authority that the source is being moved to a new device and advise them of the new device number.
