“…In this case the matrix effects were extremely severe. 140 The plasma shape is related to the ability of the aerosol sample to penetrate this high-energy medium. Thus, for teardrop plasmas, the sample tends to flow around the plasma and does not go through the center.…”

“…This is also a crucial problem in underdeveloped countries because Ar gas is either unavailable or too expensive. In order to reduce the Ar plasma gas flow rate for the sake of decreasing running cost as well as avoiding problems, low gas flow torches such as a high efficiency torch, 4,5 a reduced size (mini) torch, [6][7][8][9] a water cooled torch, [10][11][12][13] an air cooled torch, [14][15][16] and so on, were developed and those performances were examined especially for mostly radial viewing OES. It was reported that the high efficiency torches and the reduced size ones could sustain ICPs under the Ar plasma gas flow rate from 4 to 12 L min -1 with radio frequency (RF) forward power from 0.5 to 1.2 kW.…”

Spectroscopic characteristics of a spiral flow inductively coupled plasma (ICP), which could be sustained stably at 9 L min -1 of Ar plasma gas flow rate with 1.5 kW RF forward power, were studied for axially viewing ICPOES. The emission intensity profile, excitation temperature and plasma robustness were evaluated, and were similar to those of the standard ICP. The background and emission intensities of elements as well as the excitation behavior for both atom and ion lines were also examined and compared to those of the standard ICP. Since the spectroscopic characteristics of the spiral flow ICP were similar to those of the standard ICP, it could be used as a new low gas flow ICP in axially viewing ICPOES.

“…To avoid the high cooling gas ows that constitute the largest portion of the ICP's gas consumption, alternative cooling strategies for the quartz torch were investigated. Most approaches dealt with watercooling, [9][10][11][12][13] air-cooling [13][14][15] and miniaturization 16,17 of the ICP torch. Some work was focused on radiative cooling by means of ceramic materials, like Al 2 O 3 and BN.…”
