Learn English – How to say you did two things, but separately

word-choice

When describing an experiment (inside a thesis paper), I want to explain that we took a sample and did two things to it, but not together, rather as two separate experiments.

One way to write it is :

We took the sample and either did X to it, or did Y to it.

Another way is:

We took the sample and did X to it, and separately did Y to it.

Frankly I'm not happy with either forms. What's a good way to write this?

Sample taking is pretty much assumed, so no need to emphasize that at the start of your sentence. How about something like: "Samples were subjected to Kjeldahl analysis or Multiplex polymerase chain reaction followed by capillary electrophoresis"?
