And how is the evolution of the instruments themselves evolved along with the technology or along with the modalities? I've often thought those were kind of inextricably linked to each other a little bit.

Right.

And I mean, also today, myself, the concept of doing mass spectrometry was pretty novel.

And you might do that for some unknown compound that you synthesize in the lab.

But most of our analytical for small molecules, amino acid things, was all with LC and integration and fluorescence or absorbance measurements.

And so just the introduction of mass spectrometry.

And now we're looking at...

So what are your thoughts on those two points? Right, so
