Better peak shape

Good day! I ran a standard of carbon disulfide in isooctane with HP-5MS and I observed that my peak is tailing/broadening. Any suggestion on how I can achieve a better peak shape? Thank you!

What type if inlet are you using?

What inlet liners?

Injection volume and is it splitless or split?

Inlet temperature and initial oven temperature?
