WebJan 4, 2024 · The TPD spectrum of water exhibits a main peak at around 162 K, where the H + and H + (H 2 O) 2 intensities also decay in TOF-SIMS. The intact O 2 molecules desorb together with water. The O 2 TPD peak appears at higher temperature than that from O 2 adsorbed Pt(111) (∼140 K), 35 suggesting the occurrence of some attractive interaction ... WebFigure 2. TPD of pyridine from ZSM-5 The temperature-programmed decomposition of i-propyl amine should be monitored by a mass spectrometer (Figure 3). At temperatures less than 300 °C, the TPD product contains i-propyl amine. As the temperature exceeds 300 °C, the i-propyl amine is fully desorbed and the TPD products are propylene

The triple filter mass analyser is configured with a cooled shroud giving the analyser optimum sensitivity with minimum background contributions to desorption products from the sample.
Webformance is the same as on water for stock consistencies up to 6% O.D. In other words, water curves can be used to select stock pumps, as the capacity, head and efficiency are the same as for water. Medium consistency paper stock is a term generally used to describe stock between 7% and 15% O.D. consistency. Pumping of medium
