Pyris 1 TGA-MS (Perkin Elmer & Hiden)

The Pyris 1 TGA-MS (Perkin Elmer & Hiden)


TGA Design:  A vertical design with a high sensitivity balance and quick response furnace. The balance is located above the furnace and is thermally isolated from it. A precision hang-down wire is suspended from the balance down into the furnace. At the end of the hang-down wire is the sample pan. The sample pan’s position is reproducible.

Sample Atmosphere:  Static or dynamic, including nitrogen or air
Standard Furnace Temperature Range:  Subambient to 1000 °C
Scanning Rates:                  0.1 °C/minute to 200 °C/minute 
Temperature Precision:      ±2 °C
BalanceTare:                        Reproducible to ±2 μg
Sensitivity:                            0.1 μg
Accuracy:                             Better than 0.02%
Precision:                             0.001%
Capacity:                              1300 mg
Hang-down wires:               High temperature quartz
Sample pans:                        Platinum with capacity of 60 μL
Sample mass range:            Up to 1300 mg

Cooling: Forced air cooled with an external fan and internal booster purge; 1000 °C to 40 °C in less than 15 minutes under normal operation

Hyphenated techniques: Compatible with mass spectrometers (MS)

Gas switching: Fast, thorough and efficient due to reduced furnace volume. Less than 3 minutes to purge the sample area of ambient gases (remove 99% of oxygen) and replace the volume with an inert purge gas. 10 minutes to achieve a 99.99% oxygen-free environment.
