### Note Regarding Perkin Elmer Data Package for the Collision Cell MDL Study November 2012

This PDF was created by CSC in November 2012 by combining several smaller PDF files provided by Perkin Elmer. Those files contain a narrative discussion of the MDL study results and limited raw data.

Note that Perkin Elmer participated as a volunteer, arranged by EAD. Unlike the other laborat ories, Perkin Elmer was not compensated for this effort, nor could CSC or EAD formally require that they produce specific deliverables.

Therefore, this PDF file represents what CSC and EAD rece i ve d as supporting data.

### For this MDL study, all results were obtained using collision mode with KED. No reaction mode results are provided as the reaction mode was set up for experimental work which cannot be reported at this time. It is possible that this data may become available at a later date.

Dilution Factor Determination

For this work, it was decided to use gas dilution for the dilution of the FGD sample, in order to meet the internal standard recovery criterion of 60

– 12 5% recovery of the calibration blank. To determine any needed dilution, a sample of the synthetic FGD was diluted 1:1 in 1. 6% Fisher Optima grade HCl and 18.2MOhm deionized water to produce the specified reference matrix solution, hereafter simply referred to as the FGD. This FGD solution, without digestion, was analyzed to obtain approximate concentrations to assist in planning for the MDL spike solution preparation. In addition, this undigested FGD was analyzed at varying gas dilution ratios to determine the minimum dilution needed to maintain a minimum recovery of 60% for all internal

### standards. The FGD sample was initial ly run with no gas dilution and then four sequentially higher dilution ratios. In each instance, a reagent blank consisting of 2%HNO3 and 0.5% HCl was analyzed first to establish baseline intensity readings for the internal standards followed by analysis of the FGD. The intensities of the internal standards in the FGD were compared to the intensities of the internal standards in the reagent blank to determine the recovery. It was determined that gas flows of 0.78 LPM nebulizer and 0.20 LPM make up gas were sufficient to maintain Ge above the 60% criterion

. Germanium was the most matrix suppressed element of the internal standards used, most likely due to its high ionization potential. These gas dilution conditions create a dilution factor of approximate ly 3. Please see the data titled Selection of Dilution Factor for detailed results.

Preparation of Standards

All calibration standards and quality control samples were prepared from Perkin Elmer stock solutions. The MDL spiking solutions were prepared from individual 1000ppm stock solutions to accommodate the various concentrations needed for each element. The calibration and QC standards were prepared from mixed element stock solutions.

Two separate MDL spiking solutions were prepared; one for the re agent water study and another one for the synthetic FGD study. Concentrations of the two solutions were determined based on previous MDL studies on FGD as well as standard deviations of analysis of the undigested synthetic FGD and reagent blank.

The reag ent spiking solution contained: Cr 80ppb As 80ppb Se 800ppb Cd 40ppb Tl 4ppb Pb 40ppb

1.0ml of this spiking solution was added to 400g of reagent blank (2%HNO3+0.5%HCl+DI water) to create the following spike concentrations: Cr 0.2ppb As 0.2ppb Se 2.0ppb Cd 0.1ppb Tl 0.01ppb Pb 0.1ppb

The synthetic FGD spiking solution contained: Cr 400ppb As 800ppb Se 400ppb Cd 80ppb Tl 8ppb

### 1.0ml of this spiking solution was added to 200ml of the synthetic FGD (direct from the provided bottle), 200g DI water, 8ml conc HNO3, and 2ml conc HCl to create the following spike concentrations: Cr 1.0ppb As 2.0ppb Se 1.0ppb Cd 0.2ppb Tl 0.02ppb

No lead was added to the synthetic FGD spiking solution due to the inherent concentration of lead in the FGD at approximately 2ppb. P lease note that the observed concentrations of elements other than lead are generally higher than the spike concentrations due to native concentrations of all 6 elements in the FGD solution. These native levels may be low but they are detectable and definitely influence the observed concentrations and hence the MDL values themselves.

The calibration standards, LCS, and CCV were prepared from a multi

- element stock solution of 100ppm and diluted to create the re quired concentrations; 1, 10, and 100ppb for c alibration and 50ppb for the LCS and CCV. The ICV was prepared from a different lot number of the same multi

- element stock solution to create the required 40ppb ICV.

Preparation of Samples

The bulk MDL solutions were evenly distributed among 8 digestion tubes for each of the two matrices. The samples were prepared in a block digester in polypropylene digestion tubes with

screw ca ps. The digestion program ramped the samples from room temp to 85 o 

### C in approximately 30 minutes and then held the samples at 85 o 

### C for 120 minutes. For both the FGD and Reagent blank MDL studies, 8 samples were prepared and digested. The extra sample was included in the event that one sample was contaminated or had some other potential problem. Without the need to determine an outlier, the first 7 samples were used to determine the MDL values. In the FGD MDL raw data, all 8 results are presented and visible in the Excel spreadsheet but the calculations are based only on the first 7 samples.

Exposure of the reagent blank MDL s amples to the laboratory atmosphere or possibly contamination from the polypropylene over time caused lead contamination in several of the samples. Early runs of these samples did not show the lead concentrations but other QC issues were encountered. As such, a new digestion set of reagent blank samples was prepared but only 7 samples were prepared. In this second set of digestates, one of the samples was contaminated with lead which significantly affected the lead MDL. The contaminated sample was reanalyzed and the contamination was confirmed. The first sample was reanalyzed and the original results confirmed, supporting the claim of isolated contamination in the one digestate. In the MDL calculations spreadsheet, the lead MDL is presented as calculat ed from the raw data, including the contamination and a second time with the rerun of the first sample substituted for the contaminated sample. The second lead MDL value is typical of what has been determined in other MDL studies using this and similar matrices. Due time constraints, additional work to redigest and reanalyze the reagent blank MDL was not possible.

### Analysis of Sample s

The calibration, QC standards and samples were analyzed per the required sequence as modified per the SOW and did not include the Matrix Spikes/Duplicates or Undigested F DG and spiked FGD. The analytical sequence included:

### Results and Summary

The results that are provided were obtained from one run and represent what is believed to be a SOW compliant analytical sequence. Significant other results were obtained over the period of work and much experimentation was performed to further “perfect” the method for analysis of FGD, and in this particular work the focus was on low level work needed for detection limit studies. As was mentioned in the Instrumentation section, there are some results that cannot be provided at this time but may prove to be useful for the analysis of FGD. If it is concluded that this work can be validated and is approved by Perkin Elmer, it may be shared at a later date.
