“…Research fields and objectives. The research fields of the above references covered biology, 1-15 energy, 16 environment, 9,[17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] food/medical, 10-12,25-27,33-40 geology, 28,41-47 material, [48][49][50][51][52][53][54][55][56][57][58][59][60] and radionulide, 4,[22][23][61][62][63][64][65][66][67][68][69][70][71] respectively. In addition to these conventional elemental analysis topics, a study on the gas phase catalytic reaction has also been reported by using the reaction cell of ICP-QMS/QMS as the in-situ reaction field.…”

Microextraction–TQ–ICP–MS for the Direct Analysis of U and Pu from Cotton Swipes

“…Collision-reaction cell (CRC) ICP–MS was first introduced commercially in 1997, and since then most commercial ICP–MS instruments contain either a multipole CRC or a collision–reaction interface. , CRCs can eliminate interferences through nonreactive processes (which use inert gases like He) including collision induced dissociation (CID) and kinetic energy discrimination (KED), or through reaction with gases like O 2 , N 2 O, CO 2 , H 2 , and CH 4 , among many others, which can be used to shift the mass-to-charge ratio ( m / z ) of analytes and interferences . Reaction cells have been used as an alternative to sample preparation techniques like chromatographic separations to remove interferences from actinide analytes. ,,− Actinide oxides can be formed through oxidation reactions with O 2 or CO 2 gases, which shift the m / z of ions to +16 or +32 atomic mass units (amu). H 2 and CH 4 can form hydrides, shifting m / z up 1 amu, thus potentially separating the m / z of the analyte of interest away from that of interferences.…”

“…CRC technology is increasingly being applied to measurements of Pu in the presence of high amounts of U. ,,,− Oxidizing agents, such as CO 2 , O 2 , and NH 3 , have higher reactivity with U + and UH + compared with Pu + due to the thermodynamics of these reactions . CO 2 , for example, has a reaction efficiency of 0.003 for Pu + and 0.29 for U + .…”

Reaction of Np, Am, and Cm ions with CO2 and O2 in a reaction cell in triple quadrupole inductively coupled plasma mass spectrometry

“…[1][2][3] Mass spectrometric techniques help determine long-lived radionuclides. [4][5][6][7][8][9] In a previous study, 10 we applied the basic study for the ultratrace analysis of actinides using triple quadrupole inductively coupled plasma (ICP) mass spectrometry (MS/MS), which has been successfully applied in radiochemistry analysis, [11][12][13][14][15][16][17][18][19][20][21] to analyze the nuclear eld. The presence of isobaric interferences is a common issue in mass spectrometry.…”
