自美国麦克仪器公司AutoChem系列研究级高性能全自动程序升温化学吸附仪问世以来，凭借其过硬的技术优势引领化学吸附技术发展方向，解决用户化学吸附测试中的难题，并逐渐成为化学吸附分析的领导者。麦克仪器公司始终追随客户的需求，不断升级改进自己的技术， AutoChem 系列仪器已经经过了几代的升级演变。自AutoChem II 2920发布至今，它已经成为全球各个著名大学以及研究结构的首选仪器。其中不乏中国知名学府和研究院，华东理工、华南理工、天津大学、复旦大学、厦门大学、北京科技大学、北京工业大学、北京化工研究院、中石化石油化工科学研究院、中科院大连化物所、中海油天津化工研究院、兰州石油化工研究院、上海石油化工研究院等等都是AutoChem II2920的用户。

AutoChem II 2920具有如下技术特征：

4个内部温度控制区可独立加热，最高达250 ℃（TCD）。这样可以防止气体在流动过程中凝结与吸附。
小体积的内部管路保证了高分辨率与快速探测器响应，并在计算气体体积时减少错误。
高度敏感的线性热传导检测器（TCD ）确保校准体积在整个峰范围内保持恒定，从而峰面积与反应气体体积成正比关系
四个高精度的质量流量控制器提供非常准确、可程序控制的气体流量控制，保证了稳定的基线和气体体积的准确测定。
镀金TCD具有超强抗氨腐蚀性和抗氧化性，从而尽可能降低检测器损耗。
开合式加热炉能加热石英样品反应器到1100℃ 。可设定任意数量的升温速率和内置方法，方便定制的实验。 KwikCool功能冷却炉可使炉内温度迅速下降到环境温度，减少分析时间，提高测试量。
分别用于制备、载气和LOOP气的十二路进气口允许连接更多的气体，进行更为复杂的实验。例如TPR / TPO循环。
质谱仪端口和集成软件允许同时在热导检测器和质谱仪上进行检测。
蒸汽发生器允许蒸汽吸附反应，例如吡啶、苯和水。
CryoCooler冷浴槽可以在-110℃低温条件下开始进行反应，满足贵金属催化反应研究。
同时AutoChem II 2920也可以根据客户实际需要进行各种定制。
