General System Requirements

• The plasma ignition must be software-controlled and totally automated. The plasma can be ignited automatically at a user-determined time and turned off automatically after an analysis.

• The plasma must be viewable through a window on the instrument as well as through a full color plasma camera and displayed in the software. Viewing the plasma is desirable for both method development and troubleshooting.

SSN-WCSS25043 Page 2 of 6

•The system must include a computer-controlled shutter system that shields the detector between samples from long exposures to UV radiation.

• The instrument must be able to operate for best results and detection limits using a total of 9 L/min of argon (including plasma, auxiliary, nebulizer, and any other flows required for normal operation including any cooling requirements.). Higher argon usage will significantly increase operating costs for the instrument.

• Dual-viewing optics are required to allow the plasma to be viewed radially or axially. Dual viewing of the plasma provides the required flexibility by allowing trace and major concentrations of an element to be determined with the fewest possible interferences and wavelengths. The instrument must allow selection of either or both viewing modes for any wavelength in a single method

• The instrument must enable automated optimization of the plasma alignment in both the vertical and horizontal directions. The radial view must allow viewing 10 - 25 mm above the flat induction plates to reduce or eliminate the Easily Ionized Element (EIE) effect. The torch must be able to be adjusted for plasma viewing while the plasma is lit.

• The instrument should have a compressed air shear gas to cut off the cool end of the axial plasma to reduce material deposition on the entrance optic as well as to reduce selfabsorption and physical interferences. Other interface designs either require active cooling (requiring additional argon gas) or routine maintenance, and are not acceptable.

• The instrument must be able to run organic as well as aqueous matrices.

• System must be fully compliant with US EPA methodology for Method 200.7 and Method SW 846-6010

• Unit must be a bench top design with a utility free rear, enabling it to be placed directly against the wall (some service procedures may require movement from wall)

• The total width of instrument should not exceed 76 cm (30”), exclusive of autosampler and data system • The instrument must be operational with 120 cfm of airflow at the external ventilation system

• The instrument must include a water recirculator that is separate from the instrument chassis and can be place away from the instrument

• The instrument must monitor gas pressures and flows, interlocks, water flows, and plasma stability. The interlocks must be continuously monitored and if any interlock is interrupted, the plasma is shutdown automatically.

Sample Introduction Requirements

• The instrument must incorporate a high precision 4 channel, 12 roller peristaltic pump. The pump must have a tubing saving mode that slowly turns the peristaltic pump back and forth once the plasma is extinguished. This feature saves pump tubing from flattening and allows the ICP to start-up under the proper conditions.

• The vendor shall have a recommended set of sample introduction options specifically for organic matrices

• Options for other sample introduction designs should be available from the manufacturer and from third parties vendors

• The torch must be mounted in a vertical position for highest matrix tolerance.

• The operator must be able to change torch injectors without having to remove the torch assembly from the instrument.

• The instrument must include a quick-change torch module so the torch can be removed or changed quickly without excessive torch alignment.

• The sample-introduction cassette should allow adjustment (with the plasma on) for maximum performance in different matrices.

• No tools must be required for torch or sample-introduction cassette removal.

ION Source and RF Generation Requirements

• The RF generator must be computer controlled for automatic control of torch ignition, shutdown, and system warm up

• The RF generator must operate at a power setting up to 1500 watts in both axial and radial viewing modes and be controllable in 1 watt increments.

• The RF generator must have power transfer efficiency into the plasma of at least 80% and a power output stability of 0.1% or better

• The RF generator must be solid state and operate at a frequency 40 MHz providing greater robustness than lower frequencies

• The RF generator must have a “free-running” design that provides results in instantaneous compensation for impedance changes. This allows for switching between sample matrices with no need for operator adjustment of the plasma

• The RF generator must be able to respond in 50 nanoseconds to adapt quickly to changing loading and does not require an impedance matching network within

• The RF generator must have no moving parts other than cooling fans

• The RF generator must electrically decouple the plasma from the ion optics allowing independent adjustment of the ion optic parameters and the plasma conditions

• The plasma must be generated using maintenance free Flat Plate™ plasma technology rather than outdated helical-coil induction. This technology generates a transversely symmetrical plasma with highly reduced argon plasma gas flow (8 L/min on aqueous samples and producing optimal detection limits)

• The induction plates must not require water, air, or oil cooling

• The induction plates must not require any maintenance

Optical System Requirements

• The instrument must have an echelle-based polychromator covering a spectral range of 163 - 782 nm

• The spectrometer must utilize two custom-designed, application-specific, SCD detectors for simultaneous spectral range acquisition

• The spectral resolution of the system must be at least 0.006 nm at 200 nm

• The optical system must use a built-in mercury lamp to automatically update the system wavelength calibration at the 253 nm mercury emission line that can be viewed at a userselected frequency

• The instrument must automatically adjust integration times for intense and trace signals

• The entire optical system must be enclosed in a purged and thermos tatted optical enclosure

• The optical enclosure must be mounted on the same large optical bench as the sampleintroduction system.

• The optical bench must be shock mounted to the frame of the instrument so that normal floor vibrations do not affect system performance

• The sealed optical system must be purgeable with nitrogen to achieve best performance in the low UV region (165 – 190 nm). Sole Source Document for a Simultaneous ICP-OE Vendor must specify typical published 3σ detection limits for the following elements: (µg/L)

Ag 0.6 Bi 3 K 1 S 10 Ai 1 Ca 0.05 Mg 0.04 Sb 2 Au 1 Cd 0.1 Mn 0.1 Se 5 As 2 Co 0.2 Na 0.5 Tl 2 B 1 Cr 0.2 Ni 0.5 ZV 0.5 Ba 0.03 Cu 0.4 P 4 Zn 0.2 Be 0.09 Fe 0.1 Pb 3 Zr 0.5

Computer and Software Requirement The software must be capable of running in Windows 10 on a 64-bit operating system

• The software must have functions for automated system startup, shutdown and optimization tuning for optimum performance

• Must include a “Universal Data Acquisition” mode which enables users to—optionally, on demand— collect all the spectral data for every sample regardless of the elements being determined. This can then allow analysts to retroactively determine the concentrations of elements not in the original method or at alternate wavelengths, saving precious time and resources

• The software must include a semi-quantitative analysis mode

• The semi-quantitative mode must allow for the creation of custom calibrations to be created and allow the import of method parameters from existing methods so that semi-quantitative analyses are better matched to suitable calibrations based on plasma parameters and concentration ranges for a given sample type

• The semi-quantitative mode must allow for review of new or existing semi-quantitative calibrations

• The semi-quantitative mode must allow the analysis of new samples or the review of previously analyzed data with a semi-quantitative calibration applied to be able to review possible issues due to unknown interferences or identify elements that were previously not quantified in the original analysis

• To provide ease-of-use the system software must include the following features:

• Software must allow users to be able to easily change instrument parameters (such as number of replicates) without creating a new method prior to measurement to facilitate methods development efficiencies

• The software must allow for priority samples to be inserted at any time during an analysis without stopping the actual sequence

• The software must also allow many samples to be appended into a run without interrupting the run

• Software must be able to save spectra and a copy of the exact method used for their acquisition for traceability requirements in audited laboratories

SSN-WCSS25043 Page 5 of 6

• Exact Methods must be retrievable from results saved even if methods were deleted or modified under the same name at a later time

• The software must be able to display all of the peaks from an analysis simultaneously *The instrument must be able to read both background and emission data simultaneously and allow for automatic background correction

• The software must be able to display calibration curves for all of the elements analyzed during or any time after the run

• Calibration curves must be stored and be able to be recalled or modified for later use

• The software must have a library of analytical wavelengths containing all the major wavelengths for all elements, providing a list of preferred or recommended wavelengths *The instrument must have the ability to do two forms of spectral interference correction. Traditional Interfering Element Corrections (IEC) must be available and the system must be able to calculate these values automatically. The system must also have advanced peak deconvolution algorithms (PLS) to help correct for severely structured background.

• Must include a continuous graphics mode. Continuous graphics should allow one to look at how the instrument is operating by acquiring and displaying data in real time. The operating parameters of the instrument and RF generator can be modified as data are acquired, allowing method optimization to be further enhanced. For example, RF power and nebulizer flow can be changed while their impact is monitored. Peristaltic pump speed can be set to improve noise and signal intensity, maximizing system performance.

• Automated quality control checking features

• Real-time graphics with the ability to display transient and continuous signal profiles

• Real-time plotting of internal standard responses

• Single-click button to export analytical data as an Excel file

• QC protocol limits on measured values, allowing the analyst to define when and how an action is taken, and to specify a second QC action for automatic operation in the event that the first action fails

• All analytical raw data must be retained and stored on the hard disk as well as being encrypted to prevent tampering per EPA requirements to support a complete data audit trail

• Per EPA methods requirements the time and date must be printed on each sheet of data generated by the system printer *On-line help with quick steps to reference entire instrument user manual

• Videos to assist with system use and maintenance

• Data reprocessing on stored data without re-running samples for changes of calibration points, internal standard points or curve fit mode

• The software must be capable of supporting a syringe-pump based auto dilution system

• The software must support auto dilutions by both a global dilution factor, variable dilution factor, and/or serial dilutions for samples out of range

• TCPIP monitoring of system diagnostics for remote service troubleshooting and remote operation of system
