* Fact: A fact is something that can be objectively verified. We would need to see the research, the method, and evidence of its effectiveness to confirm if it's truly a new discovery.

* Opinion: The statement implies a level of certainty ("has discovered") that may not be fully substantiated. It also uses subjective language like "complicated" which can vary in interpretation.

To make this statement factual, it would need to be rephrased in a more neutral and verifiable way, such as:

* "The research team has proposed a new method for conducting this chemical analysis."

* "The research team has developed a new method for conducting this chemical analysis."

These versions avoid strong claims and emphasize the team's work without stating definitively that a discovery has been made.
