Agilent (formerly Varian) mass spectrometry pre stage vacuum pump equipment

1. Agilent (formerly Varian) pre mass spectrometry trueEmpty pump equipmentintroduction

The Varian DS102 is a two-stage rotary vane wet vacuum pump produced by Agilent Technologies (formerly Varian Corporation of the United States), designed specifically for high vacuum systems, especially used as a front-end pump in mass spectrometers. Its core function is to provide a primary vacuum environment for turbo molecular pumps, ensuring the stable operation of high vacuum systems. This pump is characterized by an oil lubricated two-stage rotary vane structure, which balances performance and cost-effectiveness, and is widely used in scientific research, medical, industrial, and environmental monitoring fields.

performance advantage

·Double stage rotary vane design: reduces working temperature, minimizes oil vapor reflux under low pressure, and improves pumping efficiency and stability.

·Oil lubrication system: Ensure sealing and lubrication, extend pump life, but require regular maintenance (such as oil change and filter cleaning).

·Low oil return rate: reduces the risk of oil pollution, protects the cleanliness of high vacuum systems, and is compatible with precision instruments such as mass spectrometers.

·Wide compatibility: Supports serial connection with molecular pumps, mass spectrometers, freeze dryers and other equipment to build a complete vacuum system.

3.Agilent (formerly Varian) mass spectrometry pre stage vacuum pump equipmentMaintenance and Precautions

·Regular maintenance: It is necessary to replace the vacuum pump oil (recommended Agilent special oil) every 6-12 months, clean the oil circuit and filter element, and check the aging condition of the seals.

·Oil pollution control: To avoid oil vapor pollution in high vacuum systems, it is recommended to equip them with oil mist filters or cold traps.

·Operating environment: Ensure an ambient temperature of 5-40 ℃, avoid dust and corrosive gases from entering, and extend equipment life.

·Alternative trend: In high cleanliness demand scenarios such as semiconductors and photovoltaics, dry pumps (such as vortex pumps) are gradually replacing wet pumps, but DS102 still dominates due to cost-effectiveness and mature technology.
