Data Flags & Calculations:

Any analytical tests or individual analytes within a test flagged with a Qualifier indicate a deviation from the method quality 

system or quality control requirement. The qualifier description is found at the end of the Certificate of Analysis (sample results) 

under the qualifiers heading. All results are reported on a dry weight basis unless otherwise noted. Subcontracted data 

included on the Duke Certificate of Analysis is to be used as information only. Certified vendor results can be found in the 

subcontracted lab final report. Duke Energy Analytical Laboratory subcontracts analyses to other vendor laboratories that have 

been qualified by Duke Energy to perform these analyses except where noted.

Data Package:

This data package includes analytical results that are applicable only to the samples described in this narrative. An estimation of 

the uncertainty of measurement for the results in the report is available upon request. This report shall not be reproduced, except

Mr. Perkins,

Attached is the report associated with four (4) aqueous samples submitted for total mercury and 

selenium speciation analysis on November 6, 2013. The samples were received in a sealed 

cooler at -0.1°C on November 7, 2013. Selenium speciation analysis was performed via ion 

chromatography inductively coupled plasma collision reaction cell mass spectrometry (IC-ICPCRC-MS). Mercury quantitation was performed via cold vapor inductively coupled plasma 

mass spectrometry (CV-ICP-MS). Any issues associated with the analysis are addressed in the 

following report. 

If you have any questions, please feel free to contact me at your convenience. 

 Sincerely, 

Jeremy Maute

November 20, 2013 

1. Sample Reception 

Four (4) aqueous samples were submitted for selenium speciation analysis on November 6, 

2013. Three (3) additional samples were submitted for total mercury quantitation. All 

samples were received in acceptable condition on November 7, 2013 in a sealed container at 

-0.1°C.

All samples were received in a laminar flow clean hood, void of trace metals contamination 

and ultra-violet radiation, and were designated discrete sample identifiers. The 40mL 

borosilicate glass vials submitted for total mercury were preserved with bromine 

monochloride (BrCl) solution. The resulting samples were stored in a secure polyethylene 

container, known to be free from trace metals contamination, until the analyses could be 

performed. 

An aliquot of each sample requiring selenium speciation evaluation was filtered (0.45μm) 

and each filtrate was stored in a secure, monitored cryofreezer (maintained at a temperature 

of -80°C) until selenium speciation analysis could be performed via ion chromatography 

inductively coupled plasma collision reaction cell mass spectrometry (IC-ICP-CRC-MS). 

2. Sample Preparation 

All sample preparation is performed in laminar flow clean hoods known to be free from trace 

metals contamination. All applied water for dilutions and sample preservatives are 

monitored for contamination to account for any biases associated with the sample results. 

Total Mercury Quantitation by CV-ICP-MS All samples and preparation blanks for total 

mercury quantitation were preserved with 2% (v/v) BrCl. The resulting samples were 

analyzed for mercury via cold vapor inductively coupled plasma mass spectrometry (CVICP-MS). 

Page 9 of 16
Selenium Speciation Analysis by IC-ICP-CRC-MS Prior to analysis, an aliquot of each 

sample was filtered with a syringe filter (0.45μm) and injected directly into a sealed 

autosampler vial. No further sample preparation was performed as any chemical alteration of 

a sample may shift the equilibrium of the system, resulting in changes in speciation ratios. 

3. Sample Analysis 

All sample analysis is preceded by a minimum of a five-point calibration curve spanning the 

entire concentration range of interest. Calibration curves are performed at the beginning of 

each analytical day. All calibration curves, associated with each species of interest, are 

standardized by linear regression resulting in a response factor. All sample results are 

instrument blank corrected to account for any operational biases associated with the 

analytical platform. 

Prior to sample analysis, all calibration curves are verified using second source standards 

which are identified as initial calibration verification standards (ICV). 

Ongoing instrument performance is identified by the analysis of continuing calibration 

verification standards (CCV) and continuing calibration blanks (CCB) at a minimum interval 

of every ten analytical runs. 

Total Mercury Quantitation by CV-ICP-MS The sample fractions for total mercury 

quantitation were analyzed by cold vapor inductively coupled plasma mass spectrometry 

(CV-ICP-MS) on November 18, 2013. Aliquots of each sample are reacted with a reductant 

in-line and transported to a gas-liquid separator. The volatile elemental mercury that is 

formed is then swept by a stream of argon gas into a radio frequency (RF) plasma where 

energy-transfer processes cause desolvation, atomization, and ionization. The ions are 

extracted from the plasma through a differentially-pumped vacuum interface and separated 

on the basis of their mass-to-charge ratio (m/z) by a mass spectrometer. A solid-state 

detector detects ions transmitted through the mass analyzer and the resulting current is 

processed by a data handling system. 

Selenium Speciation Analysis by IC-ICP-CRC-MS Each sample for selenium speciation 

analysis was analyzed by ion chromatography inductively coupled plasma collision reaction 

cell mass spectrometry (IC-ICP-CRC-MS) on November 15, 2013. An aliquot of each 

sample is injected onto an anion exchange column and mobilized by a basic (pH > 7) 

gradient. The eluting selenium species are then introduced into a radio frequency (RF) 

plasma where energy-transfer processes cause desolvation, atomization, and ionization. The 

ions are extracted from the plasma through a differentially-pumped vacuum interface and 

travel through a pressurized chamber (CRC) containing a reaction gas which preferentially 

reacts with interfering ions of the same target mass to charge ratios (m/z). A solid-state 

detector detects ions transmitted through the mass analyzer and the resulting current is 

processed by a data handling system. 

Retention times for each eluting species are compared to known standards for species 

identification.

4. Analytical Issues 

The overall analyses went well and no significant analytical issues were encountered. All 

quality control parameters associated with these samples were within acceptance limits.

The estimated method detection limits (eMDLs) for selenite, selenate, and selenocyanate are 

generated from replicate analyses of the lowest standard in the calibration curve. Not all 

selenium species are present in preparation blanks; therefore, eMDL calculations based on 

preparation blanks are artificially biased low. 

The eMDL for methylseleninic acid and selenomethionine is calculated from the average 

eMDL of selenite, selenate, and selenocyanate. The calibration does not contain 

methylseleninic acid or selenomethionine due to impurities in these standards which would 

bias the results for other selenium species. 

The eMDL for mercury has been calculated using the standard deviation of the preparation 

blanks preserved and analyzed concurrently with the submitted samples. 

If you have any questions or concerns regarding this report, please feel free to contact me. 

Sincerely, 

Jeremy Maute
