RE: SCILAB BOSTON, INC. Job Number 101101891 P.O. # IS-71108.0017 IS-71108.0017; (99 Church St.)
Dear Mark Porta:
Enclosed are the results for TEM asbestos analysis of the following SCILAB BOSTON, INC. samples received at SCILAB on Tuesday, October 30, 2001, for a 14 day turnaround:
0110-372-1,0110-372-2,0110-372-3,0110-372-4,0110-372-5,0110-372-6
The 6 samples were filtered and prepared according to Water analysis under the EPA-600/4-83-043 "Analytical Method for Determination of Asbestos Fibers in Water" (1983) with any method departures noted in the Table 1 footnote. Scientific Laboratories, Inc. uses the "Grid Square" method of counting and the concentration is calculated in millions of fibers per liter (MFL).
Table I represents a summary of all pertinent information used for the calculations. Included are the size of each structure counted, concentration, structure concentration greater than 10 microns in length, type of asbestiform material detected and the analytical sensitivity, which represents the concentration by the detection of one fiber in the TEM fiber count. Appendix "A" contains copies of the Fiber Count Sheets, showing the raw data for examination. These data sheets contain information for fiber length/width, fiber type, structure morphology and pertinent information on EDS, SAED and photography.
This report relates ONLY to the sample analysis expressed as millions of fibers per liter (MFL). SciLab assumes no responsibility for customer supplied data such as "sample location' or "the condition of the water sample before arriving at SciLab". This report must not be used to claim product endorsement by SciLab, NVLAP, ELAP or any agency of the U. S. Government. The National Institute of Standards and Technology Accreditation requirements, mandates that this report must not be reproduced, except in full without the approval of the laboratory.
SciLab appreciates this opportunity to serve your organization. Please contact us for any further assistance or questions.
