27、epi ece , 1 OX. (2) Apochromatic objective, 43X (4 mn) with a 0.95 numerical aperture, and a correction col lar for cover glass thickness vari ation. (3) Aplanatic apochromatic sub-ctage condenser of high numerical aperture. (4) Stage micrometer, consisting of a reticle mounted on a standard 1- by 3
28、-inch glass slide. The reticle has a millimeter scale divided into 100 divisions, each scale division being equivalent to 10 microns. (5) Microscope slides, glass, standard 1- by 3-inch. (6) Cover glasses, No. 1, 3/4-inch diameter. (7) Projection equipment and screen. A right-angled eye- piece lens
29、may be used together with a projection screen or a ground glass screen, The distance between the projection screen and the microscope must be capable of being varied, (b) Transparent ruler, graduated in millimeters. (c) Hand magnifying glass for better viewing when measuring the particles projected
30、on the screen. (d) Eye-dropper . (e) Logarithmic probabi 1 i ty graph paper. (f) Beaker, 200-ml capacity, tall form. (9) Lignt mineral oil.

Place the micrometer slide on the stage of the microscope in the normal- position. Project the image on the screen. Adjust the distance be
32、tween the microscope and the screen until 67 millimeter divisions of the transparent ruler are equal to 10 aivisions of the image on the screen. One division of the ruler is now equal to 1.5 microns. 4.4.4.6.3 Procedure. (a) Preparation of sample on slides . Weigh approximately 0.100 g of specimen i
33、nto each of 2 beakers. To one, add 20 ml of light mineral oil and mix with the electric stirrer for 5 minutes + 30 seconds. While stirring, withdraw a portion of the mixture with an eye-dropper from a point approximately one-fourth the diameter of the beaker, measured from the inside wall of the bea
34、ker and just above the top of the stirrer blades. Imediately wipe off the outside of the eye-dropper and deposit one drop of the mixture on a clean, dry microscope slide. Cover the drop with a cover glass. Prepare a second slide in the same manner. Follow the same procedure with the second beaker an
35、d prepare a second pair of slides. (b) Measurements. Mount one of the slides on the microscope stage and project the image. Place the transparent ruler horizontally across the image so that the field is approximately bisected. Determine, to the nearest millimeter, the maximum length of the horizonta
36、l projection of each particle successively encountered regardless of the orientation of the particle, excluding clusters of particles or agglomerates. When the edge of the field of vision is reached, continue measurements parallel to the above measurement but sufficiently distant so that none of the
37、 previously counted particles are measured. Continue traversing the field completely and measuring particles until at least 200 particles having a length of over 1.5 microns are counted. A hand magnifying glass may be used to assist in the measurement of the particles. If one-fourth or more of the f
38、ield of vision is occupied by clusters of particles (agglomerates) discard the sample in that beaker and pre- pare a replacement for determination. Disregard any results from that beaker and use the results from a replacement beaker in which the par- ticles are not agglomerated when averaging the re
39、sults from the four slides. Pnotomicrograph techniques are permitted in the particle counting in lieu of screen projection. (c) Tabulation of frequency distribution. As the particles are measured, tally them into class intervals as follows: I -. Provided by IHSNot for ResaleNo reproduction or networ

43、 intercept. Repeat the procedure for each of the remaining slides. Average the results obtained.
