Oxygen addition may be needed to prevent carbon buildup from organic<br />
solvents on the ICP torch or ICP-MS sampling cones (sampler and<br />
skimmer). Argon or nitrogen addition gas can help improve analyte<br />
signal intensity and/or stability, expecially for ICP-MS. Flow rates for<br />
these gases can vary considerably depending upon the application and<br />
the model ICP or ICP-MS. Typical flow rate ranges are:<br />
a O2 : 10 to 50mL/min<br />
b Ar : 0.05 to 0.20 L/min<br />
c N2 : 3 to 10 mL/min<br />
