V&F Newsletter 03 2013 - 16 Dezember 2013 - nur in Englisch erhältlich!

Welcome to the new release of our V&F Newsletter – a service of the V&F Analyse- und Messtechnik Team!

In this newsletter we inform you about the following topics:

  • “Switchable Pressure Regulating Unit" is available
  • “Internal Calibration Gas Cylinders” are available
  • Windows XP in a virtual machine using VMWare

Switchable Pressure Regulating Unit is available

V&F has released a new add-on product for our range of process mass spectrometers: a Switchable Pressure regulating Unit. It allows the measurement of low and high concentration with one single configuration of the analyzer. This is realized with two inner capillaries (fused silica) with different diameters, which can be switched by valves.

So, one analyzer can be used in different applications, where different detection limits are required. Since switching time is rather short (few seconds), it is possible to measure low and high concentrations almost simultaneously.


Features, benefits:

  • Analyzer can be used in different applications without changing the gas inlet blocks
  • Switching between 2 inner capillaries within seconds
  • Huge dynamic range >10^5

"Internal Calibration Gas Cylinders" are available

The Internal Calibration Gas Cylinders are an optional add-on product for the V&F process mass spectrometers. Up to three 1l – cylinders can be installed inside the analyzer, which leaves 3 ports for external cylinders on the front panel. This feature allows a review of sensitivity and stability of the analyzers, where no external calibration gas cylinder is available.

Gas consumption is reduced to a minimum by a capillary in order to extend the usage time of each gas cylinder. The fill level of each cylinder can be reviewed in the V&F Viewer software, where also alerts on low fill levels can be set. All three cylinders can be filled with different gases to the customer’s needs.

The bottle holder frame is mounted above the electronic rack, including the source gas cylinders (Xenon & Krypton) and mounting positions (bottle holders) for 3 additional calibration gas cylinders.


Features, benefits:

  • No external calibration gas cylinders needed
  • Fill level control via the V&F Viewer software
  • Reduced calibration time, due to short line length

Windows XP in a virtual machine using VMWare

Microsoft Corporation will discontinue support for their operating system Windows XP within the 14th of April 2014.

Some elder V&F software products like MCP, SCP and ACP have been developed to be executable within Microsoft Windows XP. These programs are not able to run natively with Windows Vista, Windows 7 or Windows 8. Neither using the Windows XP mode within Windows 7 or Windows 8 allows you to execute MCP, SCP and ACP.

So the solution to operate MCP, SCP and ACP within a modern operating system like Windows 7 or Windows 8 is to install VMWare on the PC. VMWare allows you to install virtual machines on a physical machine (your PC) running under Windows 7 or Windows 8 with virtual machines that run under Windows XP.
