Imidacloprid and triazophos in mixture were determined simultareously by reverse phase hplc , methanol and acetonitrile and water and glacial acetic acid as mobile phase , c18 column and uv200 detecter 摘要采用c18不銹鋼柱和uv200型檢測(cè)器,以甲醇?乙腈?水的混合液為流動(dòng)相,用反相高效液相色譜法對(duì)吡蟲(chóng)啉?三唑磷復(fù)配制劑進(jìn)行定量分析測(cè)定。
So in this paper , the principle of electroptical non - invasive dual - ray methods are fist present in detail . in the theorem of simple structure and low power consumption , we select detecter with fitble wavelenth and low power msp430 processor , and design high stable ray - emitt circuit , low noise pre - amplifier , background disturbance counteract circuit , the signal are low - filtered and sent to msp430 " a / d transform directly to digital signal processing 為此,本文詳細(xì)分析了光電無(wú)創(chuàng)雙光束法測(cè)定脈搏血氧飽和度的基本原理,在結(jié)構(gòu)簡(jiǎn)單,功耗小的原則下,選用合適發(fā)光波長(zhǎng)的探頭和信號(hào)處理器,設(shè)計(jì)出光強(qiáng)穩(wěn)定的發(fā)光電路,低噪聲前級(jí),以及本底干擾對(duì)消電路,通過(guò)兩級(jí)低通直接送至ti公司的超低功耗混合信號(hào)處理器msp430進(jìn)行a / d變換得到原始的數(shù)字信號(hào)。
