Deionized distilled water (DDW) 7.0 Procedure 7.1 Preparation 7.1.1. Weighing Area A. Clean the weighing area with paper towels and deionized distilled water. B. Locate teflon coated forceps and standard weights. C. Prepare the balance as outlined in "Calibration and Operation of the Mettler Balance" (UA-L-1.1). D. Turn on the computer and type "cd\balance" to go to the "balance" sub-directory. E. Once in the Balance subdirectory, type "Balink Numeric Stable Right" to start the program and setup the balance (UA-L-1.1; 7.2.3.A-C). 7.1.2. Computer File Set up A. Computer files are created in the tracking system as they are received. A file consist often sample ID numbers with a field for the balance weights in a database file (UA-D-28.0). B. The files are created and stored in the "G:\Filters" subdirectory with the following format "mm/dd/yffc.dbf, where; "mm" is the month, "dd" is the day, "y" is the last digit of the year (i.e. 6 for 1996), "ff* is the sample prefix, "c" is a alphanumeric counter (i.e. A,B,C,...) for multiple files created on the same day, and "dbf' is the dbase program suffix. C. The tracking system (UA-D-28.0 ) prompts during the logging in procedure, pre- field and post-field, for the creation of the computer datafile. Type "y" for yes and follow the file naming convention listed above. D. Seperate filters into groups of five and scan into the tracking system using the light pen. After each five filters enter one of the two class S calibration weight ID numbers (#9800007, #9800008) which is appropriate for the general weight of the filter class. For example, 27mm filters generally weigh -20 mg thus #9800008, the 20 mg weight, ID number is entered. E. After the tenth filter press escape to back out of the program which saves the file to "G:\Filters", a subdirectory restricted to input by lab personnel only. Mark the file name on the filter weighing backup forms (figure 1-5,7). 7.2. 25mm and 37mm Teflo Filters 7.2.1 Conditioning 25mm and 37mm Teflo Filters ------- SOP# UA-L-9.1 Revision #1 15 May., 1999 Page: 4 of 20 A.

Wait five to ten seconds after stability indicator dot goes out, and depress the hand switch transferring the weight to the computer screen. Follow instructions on recording weights with the computer (see 7.5.1.A-I). H. Record the weight onto the "Vacuum Dust Pre-weight Form" (figure 5) and "Vacuum Dust Chain of Custody" (figure 6). Slight changes in the scales environment may cause slight variations in the display. Recorded values are valid if they reflect the displayed value at the time of the first reading. ------- SOP# UA-L-9.1 Revision #1 15 May., 1999 Page: 8 of 20 I. Return the filter to its respective container with its chain of custody record. J. Close the balance access doors and allow the display to return to zero. If the display does not return to 0.00000, this may indicate zero-drift. Re-zero the display and weigh the filter again following steps F through I. K. Remove a plastic cable tie and measure following step F through J substituting "plastic cable tie" for "filter". Record the weight on the "Vacuum Dust Pre-weight Form" (figure 5), and "Vacuum Dust Chain of Custody" record (figure 6). Place it in the filter bag with the weighed filter. L. Repeat steps F through J for each filter and plastic cable tie. M. Return pre-weighed sentinel filters to the lab supervisor for QC and QA checks. 7.4.3 Vacuum Dust Teflon Filter Post-weighing A. Dust filters are consigned to the lab while in the freezer after field sampling (UA- F-7.1). Field sampling involves the pouching of the filter with the sample in the center and the top portion secured with the weighed cable tie making a pouch (UA-F-7.1). B. Transfer filter pouches to be weighed to the freezer in the lab (room 130A) and allow to equilibrate (10 min.). Procedures for sample processing can be found in UA-L-12.1. C. Take each filter one by one from the freezer, remove the sample pouch from its ziplock bag and weigh as quickly as possible. Weigh on the Mettler AE 166 balance in the laboratory (Room 130A) to facilitate the maintenance of the samples cold temperature. D Allow the balance to stabilize. Record the post-weight onto the "Vacuum Dust Characterization " form (figure 7), "Vacuum Dust Chain of Custody" form (figure 6) and the "Vacuum Dust Aliquot Chain of Custody" form (figure 8). 7.4.4 Vacuum Dust Post Sieving Filter Weighing A. Characterization of the vacuum dust calls for each pouch to be opened and the material in the filter pouch removed and sieved (see UA-L-12.1 for instructions on further processing). B. To determine the sieved sample weight, the cable tie and dirty filter are re- weighed. C. Weigh the filter and cable tie together. D. Wait five to ten seconds after stability indicator dot goes out. E. Record the weight onto the "Vacuum Dust Characterization" form (figure 7), "Vacuum Dust Chain of Custody" record (figure 6) and "Vacuum Dust Aliquot Chain of Custody" record (figure 8). Slight changes in the scales environment may cause slight variations in the display. Recorded values are valid if they reflect the displayed value at the time of the first reading. F. Return each filter and cable tie to its respective container to await archival. G. Close the balance access doors and allow the display to return to zero. If the ------- SOP# UA-L-9.1 Revision #1 15 May., 1999 Page: 9 of 20 display does not return to 0.00000, this may indicate zero-drift. If zero-drift is suspected re-zero the display and weigh the filter again following steps C through E. H. Repeat steps C through G for each filter-cable tie pair. Computer Operation . 1. AE163 (#195535) balance/computer interface and computer operation A. The AE163 (#195535) balance in the weighing room is equipped with a computer interface allowing the electronic recording of data from the balance display into files containing the sample ID numbers. The programs used are validated under protocol UA-D-2.0. B. Turn on the computer and type "cd\balance" to go to the "balance" sub-directory. C. Once in the Balance subdirectory, type "Balink Numeric Stable Right" to start the program and setup the balance (UA-L-1.1; 7.2.3.A-C). D. Go to the "G:\Filters" subdirectory and type "DBASE" to start the database program. The "G:\Filters" subdirectory is restricted to only lab personnel. E. From the database program find and load the file with the filter ID's, from the "G:\filters" (UA-D-1.0) drive and subdirectory, into the database program (7.1.2.G). The file name appears on each backup weighing forms. F. Follow each filter types weighing instructions (7.2.2.A-N; 7.2.3.A-G; 7.3.2.A-M; 7.3.3.A-G; 7.4.2.A-M). G. Weigh each filter in the order that they occur in the database file. After each 5 filters weigh one of the Class "S" calibration weights and record it under the appropriate ID number. H. After the stability light goes out on the balance wait 5 seconds and press the handswitch to transfer the weight to the computer. Upon transfer the computer will beep. Visually check that the weight transferred is the weight appearing on the balance display. Record the weight onto the appropriate weighing backup form (figure 1-4, 5). I. The cursor will move to the next sample ID. Repeat step 5 and 6 for each sample. J. After each group of filters is weighed and the cursor is at the end of the computer file, save the data and return the filters to the lab supervisor for QC/QA checks. K. The lab supervisor QC checks each filter weight against the value recorded on the back-up form. Once completed the file is moved from "G:\Filters" to "G:\Fil- Pre" for pre-weights or "G:\Fil-Pos" for post-weights. The "G:\Fil-Pre" and "G:\Fil-Pos" subdirectories are restricted to lab personnel only. Each back-up form is checked by an additional lab person to ensure that each form is completely filled out for quality assurance. ------- SOP# UA-L-9.1 Revision #1 15 May., 1999 Page: 10 of 20 7.6 Quality Control 7.6.1 Tolerance Limits A. The "Standard Weight" must be within 0.02 mg of its previously determined weight. B. Lab or field blank status will be assigned by the materials technician to one out of every 10 filters. The identification of blanks will be unknown to the lab staff during the pre and post weighing procedure. C. The postweight of each batch blank must be within 0.02 mg of its initially determined pre-weight. D. A visual check of individual weight values between the computer screen and the pre- and post-weight forms will be made during the weighing procedure. E. To insure the accuracy of values recorded in computer files, 10% of pre- and post- weigh forms are scanned (UA-D-24.0) and compared to recorded values. 7.6.2 Detection Limits A. Only the Mettler AE 163 (UA ID# A195535) and the AE 166 (UA ID# A201335) will be used to weigh filters (table 1). B. The sensitivity of the Mettler AE 163 and AE 166 electrobalance is specified by the manufacturer as 0.02 mg. Set at 0 to 30 g. the balance can read to 0.01 mg, whereas set to read from 0 to 162 g it can be read to 0.1 mg. C. Record all filter weight determinations to the nearest 0.01 mg. D. Net filter sample weights are assumed to have a detection limit of 0.02 mg. 7.6.3 Corrective Actions A. If the control weight (#9800007, #9800008) varies by more than + 1% from its previous weight, recalibrate the electrobalance and re-weigh all filters in the previous 5 filter sequence. 8.0 RECORDS 8.1 Data Collected by this Procedure 8.1.2 Filter Pre-weight and Post-weight Data A. The date, temperature, relative humidity, conditioning period information and technician's initials are recorded on all Pre- and Post- filter weighing backup forms (figures 1-5) at the beginning of all filter weighing sessions. B. The sample ID #, weight in grams, and status if applicable are recorded on the filter weighing forms, and vacuum dust chain of custody forms (figures 1-6, 8). C. Measured results for control weights are recorded in grams on all filter weighing forms (figures 1-8). D. 10% of filter weighing backup forms are scanned and compared with computer files to insure computer accuracy. ------- SOP# UA-L-9.1 Revision #1 15 May., 1999 Page: 11 of 20 Location/Placement of Forms 2.2 Sample Weighing Forms A. Values recorded on weighing forms (figures 1-6) are checked against the electronic files by the lab supervisor to ensure quality control and signs and dates under "Q/C". An additional lab person checks that all appropriate fields are complete and signs and dates under "Q/A" Data forms are passed to the data coordinator and backup forms are archived in files in the lab supervisors office. B. A signout sheet is kept on the file cabinet to record the removal of any backup forms. Any individual removing the files will record their name and date of removal on the sign-out sheet. ------- SOP# UA-L-9.1 Revision #1 15 May., 1999 Page: 12 of 20 Table 1.
