The equipment of WARMC thermal analysis lab includes:

  • Q2000 MDSC
  • Discovery Refrigerated Cooling System - RCS90
  • TGA-IR Q5000 IR system
  • Nicolet iS50 spectrometer

Q2000 MDSC An advanced research grade Modulated Differential Scanning Calorimeter (Fig.1a) provides high sensitivity (< 0.2 μW), and resolution, with minimal baseline bow and baseline drift (<10 μW). A unique cell designed both for heating and cooling operation ensures superior quality data (Fig.1b).

The RCS90 (Fig.2) is a two-stage cascade vapor compression refrigeration system which permits convenient programmed or ballistic cooling in DSC / MDSC® operation over the temperature range from -90°C to 550°C. The maximum rate of cooling depends on the temperature range of your experiment.


Q5000 IR: A premium performance research grade TGA featuring a sensitive vertical thermo-balance (100 mg sample weight range), an infrared furnace, and a horizontal gas purge system that combine to produce unmatched baseline flatness and  sensitivity over the temperature range from ambient to 1200°C. The Q5000 IR also offers linear heating rates to 500 °C/min and ballistic heating rates to > 2,000°C/min. Other features include Hi-Res TGA and Modulated TGA with a contamination-free sealed pan punching system, two mass flow controllers with automated gas switching.

While the TGA provides precise weight-loss information, it does not qualitatively identify the vapor being driven off. The TGA-IR combined module (Fig.3) offers complete qualitative and quantitative characterization of a thermal decomposition process, greatly enhancing the potential of the TGA technique. It enables qualitative and quantitative analysis without standards, enhanced correlation between weight loss and structure of the material, better identification of bonded and physically adsorbed small molecules such as H2O, NH3, CO2, CO, SO2, etc., off-gassing by components and structural materials. The TGA-IR combination is ideally suited for analyzing semiconductor nanomaterials, functionalized oxide nanoparticles, new drugs formulations.
