Vario one. | Liquid analyzer

Membrane inlet mass spectrometry (MIMS) technology for real-time analysis of substances from liquid

The Vario one. is an easy-to-use as well as compact quadrupole mass spectrometer that can measure the concentrations of all volatile components from liquids in real time and in continuous operation without sample preparation. The liquid analyzer is perfectly suited for process integration and masters any measurement task where measurements are taken from liquids. For example, the instrument can be used in applications such as wastewater monitoring, pollutant analysis and environmental monitoring.

Top 4 advantages of the liquid analyzer

The Specialist for Liquid Measurements

The Vario one. masters any liquid measurement task by determining volatile parameters precisely and quickly in the liquid. Since the quadrupole mass spectrometer can be easily integrated into the industrial process, it measures continuously and without disturbing the process. The mass spectrometer provides consistently accurate measurement data with low measurement noise (low noise) and high linearity, allowing changes in reactions to be tracked in real time (from 25 milliseconds). The liquid analyzer adapts perfectly to your individual application. For example, the volatility of substances in the sample stream can be increased by changing the temperature control of the membrane module.

User-Friendly Hardware and Software

The Vario one. s a liquid analyzer based on membrane inlet mass spectrometry (MIMS technology). The membrane inlet of the instrument allows online as well as inline measurements directly in the process, so no sample preparation is necessary. This saves time and resources and allows to react quickly to changes in the process, thus optimizing it. The user-friendly software architecture simplifies real-time control of the machine and visualizes the measurement data in the same user interface. The hardware is modular in design – for example, the membrane module can be replaced with only one movement.

  • Process-oriented

  • User-friendly

  • Practical

The Ideal Inlet for your Measurement Task

The Variolytics membrane inlets allow stable multi-parameter measurements from the liquid. In the membrane module there is a hydro- and organophobic membrane. At the interface of the membrane, volatile components present in the liquid are continuously transferred through the membrane into a vacuum. Then these parameters are measured directly in the mass spectrometer. The membrane inlets are easily autoclavable and can be easily replaced if necessary.

Flow Cell

With the flow cell, processes can be monitored online. For this purpose, a bypass is laid from the reaction site to the flow cell. For this reason, no probes or other components need to be inserted directly into the process. Therefore, the process is not disturbed by the measurements. In addition, the module enables the measurement to be influenced in a targeted manner, for example by setting a specific temperature or adding substances (e.g. acid to lower the pH).

In-Situ Sensor

With the in-situ sensor, measurements are made directly in the process, at the reaction site, and do not require a bypass. For this reason, the in-situ sensor has faster response times than the flow cell and therefore there is no time delay in the measurement. Processes in which very rapid changes occur can therefore be mapped in real-time using measurement technology. This membrane inlet is particularly suitable for measurements of dissolved gas concentrations.

Latest Software Architecture

… for problem-free process integration

Tired of outdated software? So are we! The Vario one. offers a software architecture that can be easily integrated into process control systems or other hardware via common interfaces. A modern user interface and smart functions make it easy to use. Automated routines even allow “stand-alone” operation for continuous measurements.
