We analyze for silicone oil dissolved in toluene and use 15% oxygen as the optional gas. We use liquid argon which lasts for about three weeks and the oxygen will last several months. You can also purchase compressed argon gas with 20% oxygen added. The compressed argon tanks do not last very long, however. Oxygen is required to take care of the carbon that forms from the organic solvent. So you could probably analyze the transformer oil directly but I can't say what nebulizer would work best.

Subject: Metals in transformer oil
I am trying to get a sense of what is the best method for determination
of metals in transformer oil sample using ICP-MS.
Does anyone analysis metals in transformer oil using ICP-MS?
