This may be a you problem. I can see the pictures no issues. Maybe they are too big for your filter or something?
@SidViscous dude baseline is looking lovely. Digging those sharp peaks too. <3 Remember…any amount of noise is normal - as long as it is always consistent so you can disregard it. AND as long as your actual peak of interest has a strong signal outside of the noise. I mean sure… its always nice to have things nice a quiet and mostly smooth - but never expect zero, there’s always something hiding somewhere.
That one of the rinsate actually looks awesome to me. Clear solvent peak, and then not too much crap. Dialing in the RT a bit more with your standards will help with integration and those other ions will get left behind instead of it trying to quantify everything. We’ll get your calibration dialed in and your method integration dialed in and you won’t even see that stuff anymore.
