Mass Spectrometer MS GAS

The MS GAS is a compact benchtop gas analyzer with mass spectrometry detection designed for complex analysis of gases and volatiles including isotopes, solvents and volatile organics. Modular inlet, highly sensitive mass spectrometer and primarily unique freezing system allows continuous weeks-long operation.

The MS GAS can be used for numerous applications in biotechnology of plants, alga, yeasts, bacteria and others, in biochemical methods, environmental analyses and many other related fields.

Measurement of gas exchange states in gaseous and liquid samples

Long-term measurements of multiple gases and volatile species by a single device

Membrane based inlet or needle valve inlet for atmospheric measurements and/or special gaseous and liquid applications

Accurate, sensitive and rapid measurements

Compact design with modular inlet structures and multiple interface options for gas exchange analysis on whole plant level or on cell suspensions

Highly efficient removal of water molecules by Stirling cooler water trap for significant enhancement of ion source lifetime

User friendly software interface

Mass Spectrometer MS GAS Mass analyses of volatiles are determined using mass spectrometer of Prisma product line based on open ion source with electron impact, two independent filaments and single quadrupole mass analyzer with variable mass ranges of 1-100 (MS GAS-100), 1-200 (MS GAS-200) and 1-300 amu (MS GAS-300).

Two types of detectors, Farraday with sensitivity lower than 10 ppm and Continuous secondary electron multiplier (C-SEM) with sensitivity lower than 100 ppb, are available for system. Highly effective vacuum pumping system is presented by the combination of diaphragm backing pump MVP and turbomolecular pump HiPace SplitFlow. Thermostat heating element performs vacuum chamber baking for cleanup from undesirable impurities inside of mass spectrometer. Electronically controlled Stirling cooler ensures highly efficient suppression of water molecules background and significantly enhances ion source lifetime. Moreover the temperature of water trap can be defined by user, which enables to monitor special volatile species. Modular inlet options includes permeable membrane probe, needle inlet and gas dosing valve (manual). Membrane probe inlet allows small levels of the dissolved species to pass through it, this type of inlet is suitable for liquid samples as well as for analysis in gaseous environments. Needle valve inlet is designed for direct measurements of volatiles in gaseous samples. The basic version MS GAS-100 is equiped with high vacuum pressure sensor to determine total pressure in vacuum chamber and with inlet pressure sensor to ensure mass spectrometer protection.

Intuitive setting of device is available via integrated touchscreen including manual mode with possibilities to change temperature of heating/cooling system and to open/close inlet valve, split-flow and safety valve. Original firmware is also enriched with automatic functions of valve opening/closing based on signal from safety pressure sensors after device turn on. Mass spectrometer tuning and acquisition of measured data are performed by software Quadera (models with PrismaPlus RGA) and PV Mass Spec (models with PrismaPro RGA). Both softwares permets user-defined protocol writing for numerous determinations of desired analytes.
