The Pyris 1 TGA-MS (Perkin Elmer & Hiden)
Introduction
TGA Design: 听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鈥檚 position is reproducible.
Sample Atmosphere: 听Static or dynamic, including nitrogen or air
Standard Furnace Temperature Range: 听Subambient to 1000 掳C
Scanning Rates:听 听 听 听 听 听 听 听 听 0.1 掳C/minute to 200 掳C/minute听

Hang-down wires: 听 听 听 听 听听听听听 High temperature quartz
Sample pans: 听 听 听 听 听 听 听 听 听听 听 听 Platinum with capacity of 60 渭L
Sample mass range: 听 听 听听听听 听 Up to 1300 mg
Cooling: Forced air cooled with an external fan and internal booster purge; 1000 掳C to 40 掳C in less than 15 minutes under normal operation
Hyphenated techniques: Compatible with mass spectrometers (MS)
Gas switching:听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.
