Kenworth Kansas City a Aluminum and cobalt were determined by ray fluorescence spectrometry Total weight was ascertained on a Cahn Electrobalance For total phenolics a modification of the impinger method was used where 1/2 of the filter was immersed in 10 cc of % Na2CO3 in an ultrasonic bath for 1 hour Following this treatment the Na2CO3 solution was extracted 3 x 25 cc with ether which was evaporated to a volume of 2 cc The ether extract was injected into a gas chromatograh using PACCAR000080 fi David Bissonnette PACCAR Inc. Page 2 a Carbowax 20M column Ether extracts were also run on the infrared spectrophotometer to estimate the phenolic content of the sample b Fiber counts were obtained microscopically using a Leitz phase contrast instrument and following the standard NPOSH procedure copy of procedure available upon request Chemical identify was established by electron microscopy analysis of individual fibers and microprobe constituents of the metal 2 PACCAR Truck Centre Edmonton Alberta Fiber a in counts were made using the same method indicated 3 Kenworth Seattle a Carbon tubes were desorbed in 1 ml of carbon disulfide left overnight and analyzed the next morning by injection in a gas chromatograph equipped with flame ionization detector and a Chromosorb 101 column By mass spectrometry the identity of the solvent vapors was determined samples appropriate standards were prepared and the reanalyzed for quantification Results are shown in the following table PACCAR000081 David Bissonnette PACCAR Inc.
