Hi,
Does anyone know which solution can I use to calibrate my Micromass Quattro Micro? The manual describe some of the then but I would like your personal opinion. I will work in a range from 70- 1000uma in both modes negative and positive. I haven’t calibrated the instrument before. Which compound do you recommend me?
Thank you!

to calibrate your instrument, i recommend you the RbICs solution because it will give you a supplementary peak at 85 in positive mode.
To prepare these solutions refer to a Quattro Lc manual or contact Micromass because they didn't find useful to indicate it in the quattro micro manual (quite surprising). However, i could send it to you if you want.
