Abstract or Summary
  • A long path dc plasma arc operated in an atmosphere of argon is described. The arc is easily ignited and operated, and is inexpensive to use. Samples were introduced into the arc as solution aerosols. Radially resolved emission measurements are reported for calcium, copper, and hafnium. The detection limit for hafnium, an element known to readily form oxides in flames, is 15 times better than emission and 10 times better than atomic absorption detection limits reported for chemical flames. Detection limits for calcium and copper were 0.01 ppm and 0.06 ppm respectively. Interference of phosphate on calcium was found to exist only in the cooler regions of the arc.
