This content analysis examines the counseling literature on multiracial individuals using the top journals. The authors conducted an exhaustive search for research articles and identified 10 published articles that addressed biracial and multiracial individuals from the years 1991 to 2013 in top‐tier counseling journals. Of the 10 counseling journals, 4 journals addressed multiracial individuals (Journal of Counseling & Development, Journal of Multicultural Counseling and Development, Journal of Humanistic Counseling, and Journal of College Counseling). Recommendations for counselors and researchers are provided.

A graphite rod electrothermal vaporizer used to introduce microliter-sized samples into a direct current plasma (DCP) atomic emission spectrometer is reported in this work. Several important experimental conditions were found to be important in achieving good analytical performance from the electrothermal vaporization (ETV-DCP) system. A combination of lowered plasma electrode sleeve gas flow rates, when compared to that commonly used in the DC plasma jet, and relatively low carrier gas flow rates resulted in very good analytical performance. Relative precision for the ETV-DCP instrument using B, Cd, Cu, Fe, and Pb solutions ranged between 4% and 10%. Limits of detection (LOD) lower than 100 pg were achieved for these elements, roughly an order of magnitude better than other ETV-DCP studies that used commercial graphite boat/furnace combinations. In addition, good calibration linearity was observed, with 2 -4 orders of magnitude linearity for the elements investigated.
