DS 402 Foreline Pump Oil Check for ICP-MS Systems

Answer

This Information Applies To: Agilent ICP-MS (7700/7800/8800)

Issue

How to check the DS 402 foreline pump to determine if the pump needs maintenance.

Background

The oil cleanliness and oil level in the DS 402 foreline pump should be checked monthly. Perform maintenance as needed, based off the monthly check. The DS 402 oil should be replaced at least once every three months, but the type of samples and number of samples analyzed may shorten the life of the oil.

Warning: Never add pump oil while the foreline pump is on, as it will introduce vaporized pump fluid into the air, which can lead to adverse health effects. Allow the pump and oil to cool, also utilize appropriate Personal Protective Equipment to avoid risk of burns.

Caution: Only use Agilent Recommended pump oil appropriate for the DS 402 foreline pump. Using a different oil can substantially reduce pump life and invalidates the pump warranty.

Steps to Follow

Checking the Cleanliness of the Oil

1. You can judge the cleanliness of the oil by the color. Compare the oil color to the chart shown below (Figure 1) and replace the oil if necessary.

Checking the Oil Level

1. View the oil-level site-glass on the front of the E2M18 foreline pump to visually confirm that the oil level is within the acceptable range when the foreline pump is powered on (Figure 2).
