Pensky-Marten Flash Tester (Fisher-Tag)

This apparatus measures flash points of fuel and lube oils, suspensions of solids, liquids that tend to form a surface film under test conditions, and other liquids. ASTM D93 must be followed in order to use this equipment. 

 Pensky-Marten Flash Tester
Main specifications

  • Temperature range: 40-370°C
  • Sample volume: >75 mL
  • ASTM: D93 
Location: A-676

TGA Q50 (TA Instruments)

Thermogravimetric analyzer (TGA) is an instrument relying in a high degree of precision in mass change, temperature and temperature change. These measurements allow different applications of the equipment: decomposition characterization of materials, study of reaction kinetics and degradation mechanism, determination of organic and inorganic content in a sample. 

 TGA Q50
Main specifications

Temperature:

  • Ambient to 1000⁰C
    • platinum pan: up to 1000°C
    • ceramic pan: up to 600°C
  • Thermocouple: Platinel II
  • Heating rate: 0.1 to 100⁰C/min
  • Precision (isothermal) ± 0.1°C
  • Furnace cooling (forced air/N2): 1000 to 50°C < 12 min

Gases allowed:

  • Purge gases: Helium, nitrogen, oxygen, air, argon
  • Hydrogen or other explosive gases are not authorized in the TGA
  • Corrosive gases are not authorized in the TGA
  • Oxygen can bused as a purge gas in the TGA. However, the furnace must be kept clean so that volatile hydrocarbons, which might combust, are removed
  • Purge gas flow rate: up to 200 mL/min; in our equipment we use 40 mL/min

Weight:

  • Maximum sample weight: 1g (depending on the pan)
  • The amount and rate of weight change in a material pan (aluminum, platinum or alumina ceramic pans)
  • The total mechanical capacity of the balance is 5 g. Thus, never allow the total weight of the sample, tare weight, hang-down wires, and pans to exceed 5 g.
  • Resolution:
    • 0.1 µg ; Accuracy ≤ ± 0.1%
    • For 200 mg range: 0.1 µg
    • For 1 g range: 1 µg
