Triple Filter Quadrupoles for Precision Analysis in UHV Science Applications: 3F/PIC Series

The IGA range from Hiden Analytical provides the ultimate tool for sorption science...

The IGA system uses the gravimetric technique to accurately measure the magnitude & dynamics of gas & vapour sorption on materials. the IGA design integrates precise computer-control & measurement of weight change, pressure, temperature, gas flow & composition. The system can automatically & reproducibly measure sorption isotherms/isobars as well as investigating thermal desorption in diverse operating conditions. The unique IGA method exploits the relaxation behaviour of the interaction process after pressure/gas composition/temperature changes to simultaneously evaluate kinetic parameters & the asymptotic uptake.

An uncompromising attitude to system design & a decade of experience in solving problems in sorption science in some of the most prestigious laboratories around the world makes Hiden Analytical the obvious & only choice for a sorption analyser.

All IGA models incorporate the following features:

Ultra-sensitive microbalance mounted in thermostatted heatsink to provide high resolution & precise long-term stability.
Pressure vessel incorporating all-metal seals designed to UHV standards to allow measurements from high vacuum to high pressure.
Basic mdels can be upgraded to extend their range of applications, as your research program develops.
State-of-the-art pressure control system capable of accurately controlling the pressure of gases & vapours across eight decades of pressure measurement.
Versatile temperature controller for ramp & set-point operations in the temperature range from cryogenic to 1000°C. Internal temperature probe to measure sample temperature
Full automation & extensive software package for experiment design, system control, data acquisition/archival, analysis & export.
Unique & innovative approach for the determination of the sorption kinetics & equilibrium isotherms - The IGA method.
Complete range of accessories including vacuum pumping stations, furnces, humidifier, water baths etc. to enable a broad range of experiments to be performed.

IGA-001 Gas Sorption System

The IGA-001 system is specifically designed as versatile gravimetric analysis system. The system can be configured to study general gas sorption processes from vacuum to high pressure as well as being used as a high pressure thermobalance with mass spectrometer interface (IGA-DSMS).
Typical Applications	Materials
• Gas sorption • Sorption kinetic analysis • Outgassing behaviour • TG studies • In situ surface analysis	• Zeolites • Carbons • Metal/intermetallic hydrides • High Tc materials/ceramics • Polymers

IGA-002 Vapour Sorption System

The IGA-002 system is specifically designed to study general vapour sorption processes from vacuum. This model includes all the features of the IGA-001 model but additionally incorporates anti-condensation protection rated to 50°C. An additional low range pressure sensor is included. The system can be fitted with a UHV pump isolation valve to achieve the best possible vacuum at the sample position and a vapour delivery system is incorporated with the pressure controller. The IGA-002 can be used to study water and hydrocarbon vapour sorption on porous materials such as pharmaceuticals, carbons, catalysts, zeolites, clays and polymers.

The IGA-002 vapour delivery and pressure control system. A broad range of liquids can be used in the reservoir to generate the vapour adsorbate.

IGA-003 Multi-component Sorption System

The IGA-002 system is specifically designed to study multi--component gas and/or vapour sorption processes from vacuum to high pressure. The system incorporates a multiple inlet mass flow control system. An internal gas delivery system injects the gas stream below the sample and extracts above enabling a defined gas composition to be established at the sample position. Flow and pressure control are independent allowing different gas compositions to be generated at different pressures. A balance purge can be provided in this system to allow the use of corrosive gases/vapours at the sample position while protecting the integrity of the weighing system. The system can be interfaced with a humidifier or vapour generator to define vapour compositions in the sample reactor. The IGA-003 system can be used to study multi-component gas/vapour sorption on materials such as carbons, zeolites, polymers and catalysts.

The IGA-003 gas injection/exhaust system. Up to four gas streams can be mixed prior to injection into the sample reactor.
