Conditional For Single Post But Not On Archive

I’m trying to create a conditional that works on blog posts but not when those posts are being displayed on an archive.

I thought that something like this would work:

is_single() && !is_archive()

My assumption was by doing this what I want to do will be output on the individual blog post pages but when those posts are displayed on a category it would not be output.

It’s not working.

How can I use a conditional that will only fire when it’s an individual blog post page and not an archive?

Thanks
