TGAs & Flash Testers

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.

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.

Main specifications
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
Helium, nitrogen, oxygen, air, argon 1000 to 50°C < 12 min
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
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: 1 µg
For 1 g range: 0.1 µg
Location: A-560
