Intelligent vacuum technology for modern analytics

Mar 20 2020 Read 331 Times

Low-noise, oil-free vacuum solutions, energy efficiency and optimised data evaluation are the requirements of analytical technology and the associated research and laboratory environments, such as mass spectrometry. Vacuum technology functions almost as a heart in most systems, as it enables processes to run. Often however, little attention is paid to the correct choice of vacuum components, which is an essential factor for the efficiency of analytical or even manufacturing processes.

Oil-free vacuum is the method of choice here. With their Ecodry Series, Leybold offers a clean, silent, compact and low-maintenance pump for use in analytical or research laboratories. This pump’s classification lies exactly in the transition area between small laboratory devices and large machines. However, the most significant innovation is undoubtedly the reduction of the noise level: “The pump is compact, low-vibration, powerful, easy to operate and very quiet in its design”, states Product Manager Alexander Kaiser. 

The Ecodry Plus was developed exactly in line with the requirements of analytical tools such as mass spectrometers and electron microscopes.  It is therefore also suitable for use in large accelerators, because there is no contamination by dust or oil. It offers users a high degree of comfort, pumping speed performance and flexibility. 

Equipped with two flexible interfaces, the pump can also be remote-controlled. When used in commercial analysis systems, it is often integrated into the plant control system and can be started, stopped, varied in speed and also monitored as required.

The Turbolab Series are plug-and-play high vacuum pump systems and offer a wide range of variants. They are compact, fully assembled and can be put into operation immediately. Different configurations cover the vacuum requirements of applications in the R & D markets and analytical applications. The unique oil-free hybrid bearing of the Turbovac i/iX turbopumps  and  the  choice  of  different  dry-compressing fore  vacuum pumps  allows hydrocarbon-free operation. These compact pump systems are delivered fully assembled and ready for operation.

They include a turbomolecular pump, a backing pump and an innovative TPU display unit. Both compact tabletop and mobile cart versions are available and offer flexible and convenient operation. Installation kits for variable mounting of the turbopump away from the pumping station frame can also be obtained. 

A wide range of accessories, such as sealing gas and / or venting valve, backing vacuum safety valve, cooling unit, heating tape, etc. facilitates the adaptation to individual requirements.

Today, data and its correct interpretation are essential factors in machine-based research and development, but also in manufacturing. Therefore, the measurement technology associated with vacuum technology is crucial for the evaluation of processes from basic research to industrial manufacturing. Leybold therefore offers a wide range of measuring instruments, sensors and components.

Turbolab systems can be equipped with Thermovac TTR for vacuum gauges and Penningvac PTR high vacuum sensors. Connected sensors are detected and pressure readings are automatically shown on the display. 

All  critical  parameters  and  operating  conditions  such  as  errors,  warnings,  frequency, temperature etc. are automatically recorded in an internal memory based on a standard time interval and can be adjusted by the user directly on site. An integrated web server allows remote control, monitoring and configuration of the Turbolab devices from the mobile device or from the computer via browser. 

A full portfolio of sensors and controllers makes the measurement and control of processes easy. Leybold offers real innovations with its sensors for vacuum measurement in numerous applications in the pressure range of 2000 to 10-12 mbar. 

These measuring devices offer higher precision, an extended measuring range, improved reproducibility and process stability. They complement the portfolio with novel interfaces and additional areas for use in lock chambers. 

Leybold offers sensors of various designs with their own characteristic measuring ranges. A distinction is made between direct and indirect pressure measurements.

These gas type independent vacuum sensors cover measurements directly and mechanically: capacitive Ceravac measuring devices and the capacitive DI/DU and piezo pressure sensors. The indirect, gas type dependent pressure measurement is possible with Thermovac sensors, a thermal conductivity vacuum gauge according to Pirani, as well as Penningvac cold cathode ionisation vacuum gauges based on the principle of the reversed magnetron and Ionivac hot cathode ionisation vacuum gauges according to Bayard-Alpert. The controllers of the Graphix and Display series complete the range of accessories. Leybold offers from one source everything from consulting to after sales options to support the customers in achieving their goals.
