Cleaning Eluent Bottles
Before preparing new eluent, all eluent bottles should be rinsed thoroughly (inside
and out) with ASTM Type I (18.2 megohm-cm) filtered and deionized water. If a
bottle still appears dirty, or if there is a slimy film on the inside, clean the bottle as
instructed below.
1. Dispose of any remaining chemicals according to municipal regulations.
2. Rinse the bottle (inside and out) with ASTM Type I (18.2 megohm-cm)
filtered and deionized water.
3. Rinse the inside of the bottle with isopropyl alcohol or methanol.
4. If algae or bacteria have left a slimy film on the bottle, use an algicide or
disinfectant (for example, dilute hydrogen peroxide).
5. Rinse cleaning chemicals out of the bottle with ASTM Type I (18.2 megohm-
cm) filtered and deionized water.
6. Dry the bottle with clean, particulate-free air.
