Frequently asked questions

Why does combined chlorine matter?
Combined chlorine is chlorine bound to ammonia and organics. It disinfects poorly and carries the familiar chlorine smell, so a rising figure usually means a higher dose is due.

Does this reagent work on its own?
Several photometric methods use two or three reagents in sequence. Check which components your method lists, and we will make sure the set is complete before it ships.

How should liquid reagents be stored?
Cool, dry and out of direct sunlight, with the cap firmly closed. Note the batch and expiry on the bottle, and work through the oldest stock first.
