K790653 is an FDA 510(k) clearance for the NOVA 3 CHLORIDE/TOTAL DIOXIDE ANALYZER. Classified as Electrode, Ion-specific, Chloride (product code CGZ), Class II - Special Controls.

Submitted by Nova Corp. (Mchenry, US). The FDA issued a Cleared decision on June 15, 1979 after a review of 71 days - a notably fast clearance cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1170 - the FDA in vitro diagnostics and chemistry framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
