A New Air-cooled Argon/Helium-compatible Inductively Coupled Plasma Torch

Abstract: A new inductively coupled plasma (ICP) torch with an air-cooling system has been designed and developed for both argon and helium plasma. The same torch and impedance-matching network could be used to generate stable Ar-and He-ICP. The torch consists of three concentric quartz tubes. The carrier gas, plasma gas, and cooling gas flow through the intervals between each tube. In an experiment, it was found that Ar-ICP could form a stable plasma under the following conditions: RF power of 1 kW, plasma gas flow rat… Show more

“…Alternatively, other researchers used water/air to cool the torch wall. 17,[19][20][21][22][23][24][25][26][27][28]34 Water cooling was very soon rejected because it lowers the sensitivity of plasma and has possible disastrous consequences in case of malfunction. Air-cooled torches, on the other hand, suffer from plasma contamination due to entrapment of air.…”

“…The popularity of the Fassel torch over similar torches is due to its lower consumption of argon gas and radio frequency (RF) power, which are both considered favorable economic factors. The same factors later encouraged many researchers to improve the Fassel torch through various optimization procedures, , building the torch with materials other than quartz, , using alternative gases such as helium or nitrogen, external cooling with air/water, , enhancing the swirling flow pattern inside the torch, , and size reduction. , …”

“…However its temperature and plasma density are lower than Ar-ICP and the analytical sensitivity of all elements except halogens is not sufficient, limiting its use. [18][19][20][21][22][23] To improve the analytical performance, the excitation/ionization source should be optimized for microdroplet injection.…”

“…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.…”
