WebbInternational Corporation, Butler, N.J.). Samples were ana-lyzed using NIOSH Method 0600 to determine the total mass of respirable dust (R.J. Lee Group, Inc., Monroeville, Pa.). The same samples were also analyzed using X-ray diffraction, NIOSH method 7500, to determine quartz, cristobalite, and tridymite concentration in the respirable mass. WebbSurface sampling for silica is similar to NIOSH method 9102. LCS Laboratory offers sampling media and laboratory testing for Quartz and Cristobalite by NIOSH method 7602 with modification for analysis of wipe samples. Method sensitivity for Quartz and Cristobalite on wipes is 10 ug/sample or 0.5% by weight of mineral dust.
