Is it possible to determine if cells are clustered by samples and not by cell types?

Question

[singcell]

I am analyzing single-cell RNA-Seq data from 10x platform using Seurat.

I have couple of questions:

1) Is it possible to determine if cells are clustered by samples and not by cell types. Which tool can I use for this analysis?

2) If there is any simple tool available to remove this effect.

Thank you.
