</p><p> 中船重工安譜（湖北）儀器有限公司研發(fā)生產(chǎn)的GFC-500A便攜式紅外CO分析儀采用非分光紅外光譜技術(shù)，基本原理是CO分子對(duì)特定紅外光具有吸收效應(yīng)，基本關(guān)系符合Beer-Lambert定律。該儀器通過(guò)設(shè)計(jì)穩(wěn)定可靠的多次反射吸收池來(lái)提高檢測(cè)靈敏度，并采用氣體濾波技術(shù)增強(qiáng)復(fù)雜環(huán)境下的抗干擾能力。 </p> <p> 非分光紅外氣體濃度探測(cè)技術(shù) ，紅外氣體濃度檢測(cè)基于氣體分子對(duì)紅外光的選擇吸收，即氣體分子只能吸收那些能量正好等于它某兩個(gè)能級(jí)的能量之差的光子。不同氣體分子因?yàn)槠洳煌Y(jié)構(gòu)所決定的不同能級(jí) 而吸收不同頻率的光子。當(dāng)一束紅外光通過(guò)充有氣體的氣室時(shí)，氣體分子吸收光能量，吸收關(guān)系遵循Lambert-Beer 定律。如果氣體吸收譜線在入射光源光譜范圍內(nèi)，那么光通過(guò)氣體以后，在相應(yīng)譜線處會(huì)發(fā)生光強(qiáng)的衰減。非分光紅外技術(shù)采用單光束雙波長(zhǎng)的探測(cè)方法。紅外光源發(fā)出單束紅外光通過(guò)測(cè)量氣室，在探測(cè)器端設(shè)置 2 個(gè)**的探測(cè)單元，且表面附有的濾光片窗口，分別為探測(cè)窗口和參考窗口。探測(cè)窗口透射頻帶位于 CO 氣體吸收中心，參考窗口透射頻帶遠(yuǎn)離該區(qū)域且不被其他氣體吸收 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
