Dear Mr. Perkins, 

Attached is the report associated with four (4) aqueous samples submitted for selenium 

speciation analysis on March 14, 2011. The samples were received on March 15, 2011 in 

a sealed cooler at 0.7o

C. Selenium speciation analysis was performed via ion 

chromatography inductively coupled plasma dynamic reaction cell mass spectrometry 

(IC-ICP-DRC-MS). Any analytical 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,

Project: Allen – FGD Alternative Fuels Test Burn #3 - Daily (LIMS # J11030228) 

March 24, 2011 

1. Sample Reception 

Four (4) aqueous samples in 125mL HDPE bottles (provided by Applied Speciation 

and Consulting) were submitted for selenium speciation analysis on March 14, 2011. 

The samples were received on March 15, 2011 in a sealed container at 0.7o

C. 

The samples were received in a laminar flow clean hood void of trace metals 

contamination and ultra-violet radiation. Upon reception, the samples were 

designated discrete sample identifiers. An aliquot of each sample was filtered 

(0.45μm) and these filtrates were stored in a secure, monitored cryofreezer 

(maintained at a temperature of -80oC) until selenium speciation analysis could be 

performed via ion chromatography inductively coupled plasma dynamic reaction cell 

mass spectrometry (IC-ICP-DRC-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. 

Selenium Speciation Analysis by IC-ICP-DRC-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 the samples may shift the equilibrium of the system resulting in 

changes in speciation ratios. 

Analytical Lab 

Page 9 of 25
3. Sample Analysis 

All sample analysis is precluded 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 

minimal interval of every ten analytical runs. 

Selenium Speciation Analysis by IC-ICP-DRC-MS All samples for selenium 

speciation analysis were analyzed by ion chromatography inductively coupled plasma 

dynamic reaction cell mass spectrometry (IC-ICP-DRC-MS) on March 11, 2011. 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 

(DRC) containing a specific reactive 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 very well and no 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. 

Analytical Lab 

Page 10 of 25
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. 

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

me. 

Sincerely,
