Sample Pre-Preparation Sample preparation begins with pre-preparation which may include chemical reduction of the matrix, heating the sample to dryness or heating in the muffle furnace. The end result is a How Do I Remove Asbestos Siding In North Carolina sample which has been reduced to a powder that is sufficiently fine to fit under the cover slip. 

Analyze different phases of samples separately, e.g., tile and the tile mastic should be analyzed separately as the mastic may contain asbestos while the tile may not. (a) Wet Samples. Samples with a high water content will not give the proper dispersion colors and must be dried prior to How Do I Remove Asbestos Siding In North Carolina sample mounting. 

Remove the lid of the scintillation vial, place the bottle in the drying oven and heat at 100 deg.C to dryness (usually about 2 h). Samples How Do I Remove Asbestos Siding In North Carolina which are not submitted to the lab in glass must be removed and placed in glass vials or aluminum weighing pans before placing them in the drying oven. (b) Samples With Organic Interference -- Muffle Furnace. 

These may include samples with tar as a matrix, vinyl asbestos tile, or any other organic that can be reduced by heating. Remove the sample from the vial and weigh in a balance to determine the weight of the submitted portion. Place the sample in a muffle furnace at 500 deg.C for 1 to 2 h or until all obvious organic How Do I Remove Asbestos Siding In North Carolina material has been removed. 

Retrieve, cool and weigh again to determine the weight loss on ignition. This is necessary to determine the asbestos content of the submitted sample, because the analyst will be looking at a reduced sample. Heating above 600 deg.C will cause the How Do I Remove Asbestos Siding In North Carolina sample to undergo a structural change which, given sufficient time, will convert the chrysotile to forsterite. 

Heating even at lower temperatures for 1 to 2 h may have a measurable effect on the optical properties of the minerals. If the analyst is unsure of what to expect, a How Do I Remove Asbestos Siding In North Carolina sample of standard asbestos should be heated to the same temperature for the same length of time so that it can be examined for the proper interpretation. 

Samples With Organic Interference -- THF Vinyl asbestos tile is the most common material treated with this solvent, although, substances containing tar will sometimes yield to this treatment. Select a portion of the material and then grind it up if possible. Weigh the sample and place How Do I Remove Asbestos Siding In North Carolina it in a test tube. Add sufficient THF to dissolve the organic matrix. 

This is usually about 4 to 5 mL. Remember, THF is highly flammable. Filter the remaining material through a tared silver membrane, dry and weigh to determine how much How Do I Remove Asbestos Siding In North Carolina is left after the solvent extraction. Further process the sample to remove carbonate or mount directly. (d) Samples With Carbonate Interference 

Carbonate material is often found on fibers and sometimes must be removed in order to perform dispersion microscopy. Weigh out a portion of the How Do I Remove Asbestos Siding In North Carolina material and place it in a test tube. Add a sufficient amount of 0.1 M HCl or decalcifying solution in the tube to react all the carbonate as evidenced by gas formation; i.e., when the gas bubbles stop, add a little more solution. 

If no more gas forms, the reaction is complete. Filter the How Do I Remove Asbestos Siding In North Carolina material out through a tared silver membrane, dry and weigh to determine the weight lost. 3.4. Sample Preparation Samples must be prepared so that accurate determination can be made of the asbestos type and amount present. 

The following steps are carried out in the low-flow hood (a low-flow hood has less than 50 fpm flow): (1) If the sample has large lumps, is hard, or cannot be made to lie under a cover slip, the grain size must be reduced. Place a small amount between two slides and grind the How Do I Remove Asbestos Siding In North Carolina material between them or grind a small amount in a clean mortar and pestle. 

The choice of whether to use an alumina, ruby, or diamond mortar depends on the hardness of the How Do I Remove Asbestos Siding In North Carolina material. Impact damage can alter the asbestos mineral if too much mechanical shock occurs. (Freezer mills can completely destroy the observable crystallinity of asbestos and should not be used). 

For some samples, a portion of material can be shaved off with a scalpel, ground off with a hand grinder or hack saw blade. The How Do I Remove Asbestos Siding In North Carolina preparation tools should either be disposable or cleaned thoroughly. Use vigorous scrubbing to loosen the fibers during the washing. Rinse the implements with copious amounts of water and air-dry in a dust-free environment. 

If the sample is powder or has been reduced as in (1) above, it is ready to mount. Place a glass slide on a piece of optical tissue and write the How Do I Remove Asbestos Siding In North Carolina identification on the painted or frosted end. Place two drops of index of refraction medium n = 1.550 on the slide. (The medium n = 1.550 is chosen because it is the matching index for chrysotile. 

Dip the end of a clean paper-clip or dissecting needle into the droplet of refraction medium on the slide to moisten it. Then dip the probe into the powder sample. Transfer what sticks on the probe to the slide. The How Do I Remove Asbestos Siding In North Carolina material on the end of the probe should have a diameter of about 3 mm for a good mount. If the material is very fine, less sample may be appropriate. 

For non-powder samples such as fiber mats, forceps should be used to transfer a small amount of How Do I Remove Asbestos Siding In North Carolina material to the slide. Stir the material in the medium on the slide, spreading it out and making the preparation as uniform as possible. 

Place a cover-slip on the preparation by gently lowering onto the slide and allowing it to fall "trapdoor" fashion on the How Do I Remove Asbestos Siding In North Carolina preparation to push out any bubbles. Press gently on the cover slip to even out the distribution of particulate on the slide. 

If there is insufficient mounting oil on the slide, one or two drops may be placed near the edge of the coverslip on the How Do I Remove Asbestos Siding In North Carolina slide. Capillary action will draw the necessary amount of liquid into the preparation. Remove excess oil with the point of a laboratory wiper
