Tray Cleaning

Every Run – Perform these tasks for each run:
• Inspect Solid Load Cartridge Cap (Section 5.4.1).
• Allow the separation run to finish with a high
percentage of solvent B to flush residual compounds
from the column, internal tubing, and flow cell
(Section 5.5).
• Allow Cone Wash to run to completion (PurIon systems
only) to wash residual compounds from the fluid
interface, probe, and to clean the cone area.
• Allow Valve Wash sequence to run to completion to wash
residual compounds from the injection valve and ELSD
(if installed) flow path.
Monthly – Perform these tasks at least monthly, more fre-
quently if conditions warrant:
• Tubing inspection (Section 5.4.2)
• Collection rack and tray cleaning (Section 5.3.1).
• Monthly flow cell cleaning (Section 5.5.3).
Annually – Perform these tasks at least annually—more fre-
quently if conditions warrant:
• Change roughing pump oil (PurIon systems only).
To clean the exterior surfaces, use a cleaning cloth dampened
with a mixture of distilled water and a mild detergent. Use iso-
propyl alcohol for tougher stains.
On printed areas such as labels, avoid rubbing vigorously or
using aggressive solvents like acetone. Each will ruin the printed
text.
Do not immerse the instrument in a water bath or subject it to a
liquid spray. The instrument is not watertight and these actions
could damage the internal electronics.
Risk of fire or equipment damage. Unclean collection racks
and tray might inhibit their conductive properties. The
racks and tray must be kept clean to dissipate static
electricity.
The collection tube racks and tray are made of conductive plastic.
Dirt, film, or coatings might prevent their ability to dissipate
static electricity. To avoid problems that possibly result from an
electrostatic discharge, clean the racks and tray monthly. Use
distilled water with a mild detergent. For tougher stains, use iso-
propyl alcohol.
