Sample Preparation 

Samples were prepared for PLM and TEM bulk analysis by Chon Simpha on July 2, 2019 through July 9, 2019. Sample 

preparation consisted of the following steps:

1) Label and weigh two 8mL glass vials for each sample in the set – one vial for the PLM preparation and one vial 

for the TEM preparation.

2) Weigh out 0.1 to 0.8 grams of material and place in corresponding 8mL glass vial. Record weight.

3) Burn samples at 480° C for at least 12 hours.

4) Record Post-Ash Weight.

5) Treat ashed sample with concentrated hydrochloric acid.

6) Filter acid reduced material onto a pre-weighed 47mm 0.4um PolyCarbonate filter.

7) Place filter into drying oven for 30 minutes and then record Post-Acid Reduced weight.

8) Make four PLM slide preparations from the PLM residual ash for each sample in 1.550 dispersion oil. Make 

additional preparations in 1.605, 1.625, 1.680 and 1.700 dispersion oil as necessary for particle identification.

9) Weigh a portion of the residue from the TEM residual ash and place it into the corresponding pre-weighed 

100ml jar.

10) Fill the 100ml jar with deionized water

11) Sonicate the jars for approximate 5-minutes.

12) Filter 0.2ml to 1ml of the solution onto a 47mm 0.22um MCE filter.

13) Dry the filter for 10 minutes then collapse, carbon coat, and place on a 3 TEM grids.

PLM Analysis

Analysis was performed in accordance with NY ELAP 198.6 protocols. The analysis was conducted using an Olympus BH2 polarized light microscope (PLM) equipped with a dispersion staining objective. All four slide preparations for each 

aliquot were examined. 400-point count was performed for those samples on which asbestos or a regulated amphibole 

was observed. If no asbestos was detected on any of the slides, the percentage of fibrous components was determined 

by visual estimation. The results of this analysis are detailed below in the Discussion and Interpretation of Analytical 

Findings section for each individual sample.

TEM Analysis

Analysis was performed in accordance with modified NY ELAP Method 198.4 protocols. The analysis was performed 

using a JEOL JEM-100CX II transmission electron microscope (TEM), equipped with a Thermo Fisher Quest Energy 

Dispersive X-Ray Analyzer (EDXA), at magnifications of 19,000x. Two grids for each aliquot were examined. Twenty (20)

grid openings were examined per sample.

Modifications to the NY ELAP 198.4 Method were:

1) The residue was not placed in alcohol and prepared using the quick drop method. To obtain a more uniform 

preparation, the residue was placed in a jar and filled with 100ml of deionized water. The jar was sonicated, and 

a portion of the solution was filtered onto a 47mm 0.22um MCE filter.

2) The tremolite and chrysotile were not visually estimated. The length and width of the observed particles were 

measured and the mass of each particle was calculated using the ASTM D5756 method. All particles identified as 

tremolite were included with the counts/concentrations, regardless of size and aspect ratio.

The results of this analysis are detailed below in the Discussion and Interpretation of Analytical Findings section for each 

individual sample.

Calculations 

ASTM D5756 Mass

M = π/4 L * W2 * D * 10-12

M = mass

L = length

W = width

D = density

Percent Calculation

EFA(mm2) * 100ml * MA(g) * RW(g)

 VF(ml) * IW(g) * AA(mm2) * RJ(g) 

The calculated value is then multiplied by 100 to convert it to percent.

EFA – Effective filter area

MA – Mass of asbestos

RW – Weight of residue

VF – Volume filtered

IW – Initial weight of the sample

AA – Area analyzed

RJ – Weight of residue placed into the jar

Limit of Detection and Quantification

We used the mass of a 0.5 x 0.04-micron tremolite or chrysotile fiber, depending on what was found in each sample, as 

the basis for our calculations. Limit of detection was defined as 1 fiber and limit of quantification was defined as 4 

fibers.

Discussion and Interpretation of Analytical Findings:

PLM

All three aliquots of sample D-50 were analyzed by Peerawut Chaikeenee on July 25, 2019. No asbestos or nonasbestos amphibole variants were detected the samples. The results were calculated using the equations detailed in the 

calculations section.

TEM

Michael Greenberg analyzed sample 2 on July 29, 2019 and August 8, 2019, 2A on August 7, 2019 and 2B on August 8, 

2019. The sample consisted of a mix of talc and mica particles, with a few talc fibers/ribbons, a few titanium 

fibers/particles and a few silica fibers/particles. Chrysotile and tremolite were observed on all three aliquots. The results 

were calculated using the equations detailed in the calculations section.

308004-2 0.02725%

308004-2A 0.00015%

308004-2B 0.00367%

The following charts plot aspect ratio vs. length, aspect ratio vs. width, and length vs. width for all the tremolite particles 

counted over all three aliquots.

QC Discussion:

During preparation, one blank control sample and one reference control sample were prepared. These samples were 

prepared alongside the customer samples. The blank sample was prepared using Sigma-Aldrich Talc Powder, <10 

micron and was analyzed by Michael Greenberg on August 8, 2019. No asbestos was detected on the blank sample. The 

reference sample was made from the same Sigma-Aldrich talc powder spiked with 1% Chrysotile. The reference sample 

was analyzed by Michael Greenberg on August 8, 2019 and found to be within acceptable limits.

Our LIMS randomly selects samples for additional replicate and duplicate QC. 308004-2, 2A, and 2B/D-50 were not 

selected for any additional QC analysis.
