摘　　要：本文在化学吸收原理的基础上,利用测容法和直接法相结合的测定方式研制成功一种同时测定沼气中甲烷,二氧化碳,硫化氢和氧等成分的便携式分析器。分析器一次进样50ml,仅需1.5min左右便可完成上述4种成分的测定。与传统的利用化学吸收厥理制成的分析器相比,该分析器具有结构简单,操作方便,分析快速,仪器价格低,携带方便等优点。分析器所测定的成分,含量范围和准确度完全满足现场测试的要求。A portable biogas analyzer based on the principle of chemical absorption has been developed by means of volumetric method combined with direct method for the determination of biogas. Methane , CO2, H2S and O2 in biogas can be determined simultaneously in 50 ml of the gas sample within 1. 5 min. The analyzer has the advantages over conventional gas analyzer in simplicity, rapidity, convenience and cheapness. The analyzer can be used in the fields.
