Courier® 6i SL Datasheet

Revision A

Courier® 6i SL on-stream XRF slurry analyzer 1. Courier® 6i SL analyzer Courier 6i SL analyzer is designed for accurate and reliable on-stream X-ray fluorescence (XRF) measurement of element concentrations in slurries for up to 24 samples. The analyzer is comprised of four main components; the analyzer probe with cooling system, probe control set (PCS), sampling equipment, and the local and remote user interface PC’s. The analyzer probe contains the physical components needed for the XRF analysis; the sample measurement cell, measurement channels, X-ray tube, high voltage supply, processing electronics, and temperature control. The Probe Control Set (PCS) monitors and controls the system functions; i.e., sampling and measurement sequences. The sampling equipment includes primary samplers, multiplexers (MXA), demultiplexers (DMA), and the calibration sampler (CSA). The primary samplers take a representative sample from the process flow. The sample flow is piped to the multiplexers of the analyzer. The multiplexers direct sample streams into the measurement cell in a predefined measurement sequence, remove air and trash from the sample, and stabilize the sample flow. The calibration sampler provides a representative sample for calibration, and demultiplexers direct the reject sample flows from the calibration sampler to the desired location. The multiplexers collect composite samples from each sample stream.

2. Performance Data The Courier 6i SL analyzer is a high performance device for measuring element concentrations in slurries. 2.1. Analysis method The analysis method is Wavelength Dispersive Xray Fluorescence (WDXRF) with X-ray tube excitation and fixed crystal spectrometers. An additional Energy Dispersive (EDXRF) measurement can be performed by using an optional proportional counter and/or a Peltier cooled solid state detector.

The Courier Local user Interface (CLI 6700) touch screen display and control switches are the process operator interface for Courier 6i SL analyzer.

2.2. Element range The element range is from Calcium to Uranium (atomic numbers 20 to 92).

PC’s with network connection to the Courier can be used as remote user interfaces to display analysis results, alarms, and diagnostic data anywhere. The analyzer can be accessed remotely for customer support in parameter setup, status monitoring, and diagnostic data evaluation.

2.3. Measurement time Depending on the application, the measurement time is 15…30 seconds per stream, leading to a total cycle time of 9…14 minutes per 18 streams and 12…18 minutes per 24 streams. With two multiplexers the total cycle time is 9…11 minutes per 12 streams.

Courier® 6i SL Datasheet 2.4. Number of simultaneous assays The Courier 6i SL analyzer probe can have up to 6 parallel measurement channels, based on either fixed spectrometers (WDXRF) or energy dispersive detectors (EDXRF). The number of simultaneous assays is dependent on the application; in practice one can measure simultaneously 1-12 element concentrations and the solids content of the slurry. 2.5. Count rate There are up to 30 000 counts per second for each WDXRF measurement channel, which gives excellent counting statistics even with short measuring times. 2.6. Concentration range The concentration range is from 0.002 to 100% by weight for slurries. 2.7. Detection limit The detection limit for most elements is 3…30 ppm in slurries. For Chrome and lighter elements, elements from Cadmium to Promethium and with ED channels the detection limit is higher. 2.8. Precision With most elements, changes of the order of 0.01% can be detected at 1% level with a probability of 95% from a homogenous sample. 2.9. Short term stability Measured intensity stabilized to 0.1% in specified operating circumstances. 2.10. Long term stability The long-term instrument drift is compensated by automatic internal reference measurements. 2.11. High selectivity The high resolution of the crystal spectrometer allows measurements of neighboring elements with no peak overlap. For instance, 8 ppm Cu can be detected in sample with high level of Ni or Zn. 2.12. Accuracy The accuracy of a measurement is a function of the sample parameters, such as matrix composition, mineralization, and particle size. Under normal operating conditions, the following relative standard deviations are achieved for individual slurry sample measurements of concentration levels well above the relevant minimum detection limit of the analyzer. • Minor concentrations 3-6% • Major concentrations 1-4%

3. Specifications 3.1. Sample streams The Courier 6i SL is capable of taking up to 24 sample streams per analyzer. 3.2. Controlled sampling Controlled sampling feature increases availability of the sample lines by shutting down the sample flow and flushing the sample line periodically with water. The operation of controlled sampling is automatic, and does not need operator attendance. 3.3. Multiplexer (MXA) Pneumatically actuated sample multiplexer for 6 sample streams with composite sampling feature. • Primary sample flow rates: 70…200 l/min (18…53 GPM) recommended, 300 l/min (80 GPM) maximum, 40 l/min (10 GPM) minimum • Primary sample line: Inlet OD 60.3 mm/G2” • Primary reject flow rate and fitting: 300 l/min (80 GPM) maximum, OD 76.1 mm/G2 ½” 3.4. Measurement cell A rubber lined measurement cell with selftightening window with second protective window and moisture leakage detection. An optional automatic window changer (AWC) recommended. Jet sample cell provides a good analytical accuracy across wide particle size range. • Flow rate: 20…30 l/min (5…8 GPM) • Input/output fitting: Hose connector OD 16mm 3.5. Calibration sampler (CSA) The calibration sampler ensures that a representative sample is used for laboratory assaying. The calibration sampler has an automatic positioning with a feedback signal so it can be used as first stage demultiplexing device. • Outlet fitting: Hose connector OD 40 mm 3.6. Demultiplexer (DMA) The demultiplexer directs the sample flow from the calibration sampler to an appropriate return location. The demultiplexer has automatic positioning based on position feedback signal. • Inlet fitting: Hose connector OD 40 mm • Outlet fitting: Hose connector OD 50 mm

The SiPIN detectors are cooled below -20°C by an integrated Peltier element/temperature controller, and use a 100V bias voltage. 3.10. Pulse processing The pulse processing unit consists of a shaping amplifier, A/D conversion and multichannel analysis. The raw measurement results are transferred to the processor, which processes the results and controls the pulse processing units. The features include: • Up to six measurement channels, each having 1024 microchannels (32-bit count registers) to represent the pulse height spectrum. • Automatic feed back gain control, based on internal reference measurement. • A free selection of 20 element channels for intensity calculation in the measured spectra. • Genuine recording of live measurement time. • Versatile self-diagnostics, using an internal test pulse generator and internal reference measurement.
