Automatic IRMS-TPD Analyzer

We have developed an Automatic IRMS-TPD Analyzer with Microtrac BEL Corp.. It is now sold as Automatic IRMS-TPD Analyzer from Microtrac BEL Corp.

Ammonia IRMS-TPD (infrared / mass spectroscopy temperature-programmed desorption) measurements are possible with this instrument. The ammonia IRMS-TPD method allows us to quantify the number and strength distribution of each of Brønsted and Lewis acid site, and OH group identified in the IR spectrum on solids.

This instrument is applicable not only to the ammonia IRMS-TPD but also commonly to transmission IR mesurements of any kinds of solid and composition analysis of the gas contacting the solid using a mass spectrometer in flow of any kinds of gases. It is suitable for various kinds of operando analysis of solid catalysts and solids with various functions.

Moreover, as a simple in-situ IR analyzer, this instrument is useful. It allows us easily to place a self-supporting disk on a metal mesh at a fixed position close to the focus of IR beam without glass parts. It allows us to control the temperature and to introduce any kinds of gases. This improves the accuracy and efficiency of experiments and reduce the stress of operator in the IR experiments of solids.

自動IRMS-TPD装置

　本装置ではアンモニアIRMS-TPD (infrared / mass spectroscopy temperature-programmed desorption)測定が可能です．アンモニアIRMS-TPD測定によって，固体のブレンステッド・ルイス酸点それぞれ，さらにはIRスペクトルで識別可能な全ての種類の酸性OH基の数と酸強度分布を決定できます．

　さらには，この手法のみならず，常圧・減圧系での各種気体の流通下における固体試料の透過法によるIRスペクトル測定と，これに接する気相の質量分析計による組成分析が全て可能で，固体触媒・各種機能材料のオペランド分析に適しています．また，単なるin-situの透過法固体IR測定装置としても，ガラス器具を用いず自己支持ディスクを金属メッシュに載せ，いつも一定の位置(IR光の焦点近く)に固定することができ，加熱や気体の導入も手軽にでき，精度と使い勝手の面で優れています．固体触媒のIR測定におけるストレスを大幅に軽減します．
