(Centre) from the 3M Environmental Laboratory. The samples were collected from Columbus, GA. The Centre study number assigned to the project is 023-014. Specific fluorochemical characterization by liquid chromatography / tandem mass spectrometry (LC/MS/MS) was requested for ail samples. A total of 8 samples were received for analysis. The samples were prepared and analyzed by LC/MS/MS for the following list of fiuorochemicals: Table 1: Target Analysis Comoound Name Perfiuorooctane Sulfonate Perfluorooctane Sulfonvlamide Perfiuorooctanoate Acronvm PFOS PFOSA POAA ' The analytical method used was validated by Centre. The validation protocol and results are on file with Centre. Data presented here is the highest quality data available at this time. 2 Sample Receipt The samples were submitted in individual plastic containers and were not preserved. Eight individual sample containers were received. Samples were received on 05/03/00. The sample collection dates were not supplied. Chain-of-custody information is presented in Attachment A. 3 Holding Times The analytical method used was validated against a maximum holding time of 14 days. The stability of the analytes of interest for longer periods has not been determined. page 2of s 4 Methods - Analytical and Preparatory 4.1 LC/MS/MS 4.1.1 Sample Preparation for LC/MS/MS Analysis Samples were initially treated with 200 uL of 250 mg/L sodium thiosulfate solution to remove residual chlorine. Solid phase extraction (SPE) was used to prepare the samples for LC/MS/MS analysis. A forty-m illiliter portion of sample was transferred to a C18 SPE cartridge. The cartridge was first eluted with 5 mL of 40% methanol in water solution. The eluate was discarded and the SPE column was then eluted with 100% methanol. A 5 ml portion of methanol was collected for analysis by LC/MS/MS. This treatment resulted in an eight-fold concentration of the samples prior to analysis. 4.1.2 Sample Analysis by LC/MS/MS In HPLC, an aliquot of extract is injected and passed through a liquid-phase chromatographic column. Based on the affinity of the analyte for the stationary phase in the column relative to the liquid mobile phase, the analyte is retained for a characteristic amount of time. Following HPLC separation, ES/MS provides a rapid and accurate means for analyzing a wide range of organic compounds, including fiuorochemicals. Electrospray is generally operated at relatively mild temperatures; molecules are ionized, fragmented, and detected. Ions characteristic of known fiuorochemicals are observed and quantitated against standards. A Hewlett-Packard HP1100 HPLC system coupled to a Micromass Ultima MS/MS was used to analyze the sample extracts. Analysis was performed using selected reaction monitoring (SRM). Samples were extracted on 5/18/00 and analyzed by MS/MS between 5/20/00 and 5/21/00. The HPLC and MS/MS methods used for analysis and instrument parameters can be found in attachment D. 5 Analysis 5.1 Calibration A 7-point calibration curve was analyzed at the beginning and end of the analytical sequence for the compounds of interest. The calibration points were prepared at 0, 25, 50, 100, 250, 500, and 1000 ng/L (ppt) The response of the quantitation ion versus the concentration was plotted for each point. Using linear regression with 1/x weighting, the slope, y-intercept and correlation coefficient (r) and coefficient of determination (r2) were determined. A calibration curve is acceptable if r >0.985 (r2> 0.970). Calibration standards are prepared using the same SPE procedure used for samples. Calibration check standards were analyzed periodically (every three to five sample injections) throughout the analysis sequence. Compliance is obtained if the standard analyte concentrations are within +/-20% o f the actual value. For the results reported here, calibration criteria were met. PAGE 3 OF 5 5.2 Blanks Extraction blanks were prepared and analyzed with every extraction batch of samples. The extraction blanks should not have any target analytes present at or above the concentration of the low-level calibration standard. For these samples, the extraction blanks were compliant. Instrument blanks in the form of clean methanol solvent were also analyzed after every highlevel calibration standard, and after known high-level samples. Again, the blanks should not have any target analytes present at or above the low-level calibration standard. For the samples presented here the instrument blanks are compliant. 5.3 Surrogates Surrogate spikes are not a component of the LC/MS/MS analytical method. 5.4 Matrix Spikes Matrix spikes were prepared for every field sample (excluding blanks) at a concentration of 100 ng/L using all compounds of interest. Matrix spike recoveries are given in Attachment C. All compounds showed matrix spike recoveries between 70-130% in all samples. Field spikes were prepared* on sample MC-501H at a concentration of 100 ng/L using all compounds of interest. Field spike recoveries are also given in Attachment C. The field spike results showed low recovery for PFOSA. All other compounds showed matrix spike recoveries between 70-130%. 5.5 Duplicates All samples (excluding blanks) were analyzed in duplicate. Results are given along with the sample results in Attachment B. 5.6 Laboratory Control Samples Milliq water was spiked with all compound of interest at 25 and 250 ng/L. All recoveries for all compounds were between 70-130% in each LCS. Results are given along with the raw data in Attachment D. 5.7 Sample Related Comments Field blank samples consisted of empty containers. Forty milliliters of type I water filtered through a hypercarb cartridge was added to the empty container and analyzed in the same manner as the other samples. _ 6 Data Summary Please see Attachment B for a detailed listing of the analytical results. 7 Data/Sample Retention Samples are disposed of one month after the report is issued unless otherwise specified. All electronic data is archived on retrievable media and hard copy reports are stored in data folders maintained by Centre.
