OmniStar/ThermoStar顶级气体分析系统

OmniStar

特點:

• Integral total pressure gauge
• Integral vacuum bakeout
• Very low detection limit even for condesable gases
• Temperature controlled gas inlet (capillary)
• Automatic shut- off valve
• Simple operation
• Quantitative analysis
• Detection limit <1 ppm
• No memory effects
• Fast response time

Gas Analysis Applications

Option for Corrosive/Explosive Gas Mixtures:

OmniStar for corrosive and explosive gas monitoring is ideally suited for exhaust monitoring of gas processes, process control during production and service/maintenance of the system. The compact system monitors all key functions including purge gas flow and ensures that the scrubber is functioning properly and removing all contaminents.

Applications

• Chemical processing
• Fermentation
• Catalytic technology
• Metallurgy
• Lamp industry
• Laser technology
• Environmental analysis

Features

Analysis software Quadstar TM

• Qualitative analysis of all gases
• Quantitative analysis with on- line calculation of concentrations
• Simultaneous data acquisition from a process via Analog Input (e.g. temperature)
• Presentation of mass spectrometric data as a function of the process data
• Definition of process windows and setting of alarms
• Convenient data evaluation supported by a spectrum library, statistical and magnifying functions, and a cursor
  Xenon in air. The spectrum shows the excellent detection limit.
  Integrated over 14 scans at 10 s/amu, under optimal conditions, laboratory air.

ThermoStar?

features include:

• Even low concentrations of condensable/reactive gases are detectabie
• Minimum contact of media with metallic parts
• No chemical reactions

Analysis software Quadstar TM

• Qualitative analysis of all gases evolving during thermal analysis
• Simultaneous data acquisition from a thermal analyzer via Analog Input Module (e.g. temperature, sample weight, differential weight ioss)
• Presentation of mass spectrometric data as a function of the thermobalance temperature
• Convenient data evaluation supported by a spectrum library, statistical and magnifying functions, and a cursor
• Data exchange with other programs via binary code or ASCII files. QuadstarTM supports also DDE

Example of Application

TA of calcium oxaiate. The evolving gases water vapour (18), carbon monoxide (28), and carbon dioxide (44) are shown together with the weight and temperature as a function of time.

Option: Gas Stream Selector GSS 300
Heated gas inlet system for up to 12 gas streams
–sample gases and calibration or zero gases
