we have several Ion PI v2 chips, and we're successfully using them with Hi-Q chemistry kits. However, we're running short of Chip Preparation Solution, and Thermo has discontinued it. I know from the relevant patent
that its composition should include a sulfonic acid in an organic solvent. I was wondering if the composition was ever disclosed by Ion Torrent in its "friendly" days or if anyone could suggest a possible recipe we could try.
