Switching from helium to nitrogen as a carrier on HS/GC-MS(5977MSD/8890 GC/PAL RSI 85)

Hi all what is your experience using nitrogen as a carrier vs helium? Pros and cons...We have a 5977MSD with 8890GC and PAL RSI 85.  We are testing residual solvents currently pentane and ethanol on in process samples.  Is there literature available ?  I cannot seem to find any in here using keywords.  Thank you in advance for your input.
