Hiden - Model HPR-70 -System for Discrete Low Volume Sample Analysis

A small quantity of gas, usually at or close to atmospheric pressure, is sampled using an automated batch inlet. After expansion and consequent pressure drop the gas is analysed using a high sensitivity 500 amu quadrupole mass spectrometer.

Most minor components in the gas mixture can be measured at levels of 5 ppm or above.

• Dual compound turbo pumps and oil-free, totally dry backing pump
• Automatic dosing, expansion and accurate sampling
• Total sample pressure measurement with capacitance manometer
• Optional aliquot filling facility
• 1 litre sample reservoir
• 1 ml injection reservoir
• Optional calibration lines

• The system is supplied with MASsoft Professional software.
• This Windows 8 and Windows 10 compatible software allows control of the instrument via USB 2.0, RS232 or Ethernet. Provides comprehensive I/O for data output and for reading data from external devices for integration and display with mass spectrometer data.

• Sealed volume studies
• Discrete sample analysis
• Quantitative determination
• Remote sample acquisition
• Local analysis
