Analysis of 0.1M H3PO4 and 0.5N NaOH extracts by 7800

Hello, we perform extractables testing at my lab and we have an upcoming study of single-use thermoplastic elastomer tubing which will be extracted in the following solvents: water, 0.1M H3PO4 and 0.5N NaOH. I am obviously not concerned about running the water sample, but what other sample prep/instrument setup steps should I consider with the other two extracts? I have a 7800 with an SPS4 autosampler, quartz Scott-type double pass spray chamber and micromist nebulizer. I typically run acid extracts/digests of HNO3/HCl and I am unfamiliar with running other solvents on this system and do not want to harm the instrument. Thank you for your help!
