### Description

The Large Hadron-electron Collider (LHeC) is a proposed upgrade of the LHC at CERN. An Energy Recovery Linac in racetrack configuration will provide 60 GeV electrons to collide with the HL-LHC ion beams and, eventually, with those from the HE-LHC and the FCC-hh. Such configurations will yield electron-nucleus collisions with per nucleon centre-of-mass energies 0.8-2.2 TeV and luminosities $\sim 10^{33}$ cm$^{-2}$s$^{-1}$. They will extend the kinematic plane by about four orders of magnitude towards smaller $x$ and larger $Q^2$ than presently existing DIS and DY fixed target data. DIS measurements in such configurations offer unprecedented possibilities to enlarge our knowledge on parton densities through a complete unfolding of all flavours. In this talk we will present the latest results on the determination of nPDFs in a single experimental setup. We will also comment on the comparison with data from hadron colliders where precise factorisation tests can be performed.
