The Hiden Intelligent Gravimetric Analyzer (IGA) is a precision microbalance instrument designed to measure gas sorption in liquid and solid samples. The instrument accurately measures (P-x) vapor-liquid equilibrium data and has the ability to measure the surface area and pore size of solid samples. Additionally, the IGA instrument is coupled with an in-line mass spectrometer to analyze volatile species during thermal decomposition studies. The various temperature options range from -180 °C to 1000 °C. The instrument has an operating pressure range between high vacuum (10-9 bar) to 20 bar (~300 psi) with pressure control accurate to +/- 0.001 bar. The instrument can operate with a sample loading as small as 50 mg or as large as 5.0 g.
