✦ Synopsis

A detection limit of 0.05% quartz in calcitic and dolomitic carbonate and talc matrices is dependent upon significant counting time for optimal signal to noise ratio, utilization of peak area counts, absence of significant interfering phase(s), a known blank ( < 0.05%) for each matrix, statistically significant replications of standards, and triplicate unknown analyses. Using the internal standard method, the quantitative determination of quartz in the range 0.05-1.0% for carbonate and talc matrices has a relative standard deviation of 25%.
