So, I've been looking at ways to combine Ranger+Alchemist (or Alchemist+Ranger). I wanted to combine arrows and bombs/elixirs, but haven't found anything in the Core Rule Book for this (despite multiple mentions of crafting ammunition).
However, there is artwork on the Multi-class Ranger page of an archer with alchemy vials (one is strapped to an arrow). Talking with the GM of my PFS game, he said to check here if that's been mentioned anywhere on how to make that in the rulebook.
