DP-YUS-A2全自動油脂酸價測定儀/全自動動物油脂酸價測定儀/酸價檢測儀 酸(suan)(suan)(suan)價是表示有機物中所含(han)游(you)離(li)(li)酸(suan)(suan)(suan)數量多(duo)少(shao)的(de)一(yi)種形式(shi)。油(you)(you)脂酸(suan)(suan)(suan)價是指中和一(yi)克(ke)(ke)油(you)(you)脂中游(you)離(li)(li)脂肪(fang)酸(suan)(suan)(suan)所需(xu)氫(qing)氧化鉀的(de)毫克(ke)(ke)數。它既是油(you)(you)脂的(de)一(yi)項質(zhi)量指標，也是食用油(you)(you)脂的(de)一(yi)項食品(pin)衛生(sheng)指標。新鮮(xian)的(de)或(huo)(huo)精(jing)制油(you)(you)脂的(de)酸(suan)(suan)(suan)價都(dou)(dou)較低，因(yin)(yin)儲存或(huo)(huo)加工不當，都(dou)(dou)會使(shi)酸(suan)(suan)(suan)價增高。因(yin)(yin)此，只有加強油(you)(you)脂酸(suan)(suan)(suan)價的(de)測定，才能了解(jie)產(chan)品(pin)的(de)質(zhi)量。 DP-YUS-A2全自動油脂酸價測定儀/全自動動物油脂酸價測定儀/酸價檢測儀 繼開(kai)發 DP-YUS — 3 加強(qiang)型(xing)酸價快(kuai)速測(ce)定(ding)(ding)(ding)儀(yi)（半自(zi)(zi)動）之后，又成(cheng)功(gong)(gong)地(di)研制(zhi)了(le)全(quan)(quan)自(zi)(zi)動酸測(ce)定(ding)(ding)(ding)儀(yi)。該儀(yi)器(qi)(qi)(qi)克(ke)服了(le)用(yong)(yong)(yong)肉眼判斷滴(di)定(ding)(ding)(ding)終(zhong)點(dian)的(de)缺陷(xian)，從電路(lu)到(dao)電化(hua)分(fen)析操作都做了(le)全(quan)(quan)面更(geng)新設計。數(shu)顯(xian)器(qi)(qi)(qi)采用(yong)(yong)(yong)高亮度的(de)計數(shu)器(qi)(qi)(qi)，既方便了(le)觀察，又提(ti)高了(le)計數(shu)精度。*“電子指示(shi)劑”進行終(zhong)點(dian)判定(ding)(ding)(ding)，使儀(yi)器(qi)(qi)(qi)能(neng)(neng)(neng)檢(jian)測(ce)到(dao)滴(di)定(ding)(ding)(ding)全(quan)(quan)過程(cheng)，并能(neng)(neng)(neng)準(zhun)確地(di)觀察到(dao)滴(di)定(ding)(ding)(ding)的(de)突(tu)躍點(dian)，測(ce)繪出(chu)(chu)完整的(de)滴(di)定(ding)(ding)(ding)曲線(xian)。我(wo)(wo)們還成(cheng)功(gong)(gong)地(di)將感(gan)測(ce)電極(ji)和參比電極(ji)微型(xing)化(hua)，并精心地(di)與電解極(ji)板復合在一支電極(ji)桿上，使測(ce)試更(geng)為方便簡(jian)(jian)單。我(wo)(wo)們經(jing)過反(fan)復實驗，將電解液(ye)配(pei)方進行了(le)改進使其性(xing)能(neng)(neng)(neng)更(geng)為優(you)異，即使在冬季低溫條件下也能(neng)(neng)(neng)油(you)脂迅速溶解，保證了(le)測(ce)定(ding)(ding)(ding)的(de)精度。，因本(ben)儀(yi)器(qi)(qi)(qi)不(bu)(bu)(bu)使用(yong)(yong)(yong)化(hua)學(xue)指示(shi)劑判定(ding)(ding)(ding)終(zhong)點(dian)，在深色油(you)脂的(de)測(ce)定(ding)(ding)(ding)中(zhong)更(geng)能(neng)(neng)(neng)顯(xian)示(shi)出(chu)(chu)其優(you)越(yue)性(xing)。它能(neng)(neng)(neng)準(zhun)確地(di)提(ti)供(gong)客觀判定(ding)(ding)(ding)終(zhong)點(dian)的(de)手段，而(er)且不(bu)(bu)(bu)需(xu)配(pei)制(zhi)和標(biao)定(ding)(ding)(ding)標(biao)準(zhun)堿溶液(ye)，不(bu)(bu)(bu)用(yong)(yong)(yong)國標(biao)法所(suo)判定(ding)(ding)(ding)終(zhong)點(dian)，在深色油(you)脂的(de)測(ce)定(ding)(ding)(ding)中(zhong)更(geng)能(neng)(neng)(neng)顯(xian)示(shi)出(chu)(chu)其優(you)越(yue)性(xing)。它能(neng)(neng)(neng)準(zhun)確地(di)提(ti)供(gong)客觀判定(ding)(ding)(ding)終(zhong)點(dian)的(de)手段，而(er)且不(bu)(bu)(bu)需(xu)配(pei)制(zhi)和標(biao)定(ding)(ding)(ding)標(biao)準(zhun)堿溶液(ye)，不(bu)(bu)(bu)用(yong)(yong)(yong)國標(biao)法所(suo)判定(ding)(ding)(ding)終(zhong)點(dian)，在深色油(you)脂的(de)測(ce)定(ding)(ding)(ding)中(zhong)更(geng)能(neng)(neng)(neng)顯(xian)示(shi)出(chu)(chu)其優(you)越(yue)性(xing)。它能(neng)(neng)(neng)準(zhun)確地(di)提(ti)供(gong)客觀判定(ding)(ding)(ding)終(zhong)點(dian)的(de)手段，而(er)且不(bu)(bu)(bu)需(xu)配(pei)制(zhi)和標(biao)定(ding)(ding)(ding)標(biao)準(zhun)堿溶液(ye)，不(bu)(bu)(bu)用(yong)(yong)(yong)國標(biao)法所(suo)使用(yong)(yong)(yong)大量的(de)醚做溶劑，因此(ci)本(ben)儀(yi)器(qi)(qi)(qi)具(ju)有重現性(xing)好，無毒害，費用(yong)(yong)(yong)省(sheng)、操作簡(jian)(jian)便、易于(yu)掌握和可用(yong)(yong)(yong)于(yu)流動檢(jian)測(ce)等優(you)點(dian)，在幾分(fen)鐘內直接顯(xian)示(shi)測(ce)定(ding)(ding)(ding)結果(guo)。 本(ben)儀(yi)器主(zhu)要用于各種植(zhi)物油(you)(you)脂(zhi)、動物油(you)(you)脂(zhi)的酸(suan)價測(ce)定，經專項(xiang)調試后也可(ke)用于大米、小麥粉、牛奶(nai)、酒(jiu)類(lei)、醬(jiang)油(you)(you)等的酸(suan)度或總酸(suan)度的測(ce)定。本(ben)儀(yi)器可(ke)廣泛用于糧(liang)油(you)(you)、食品、發酵、輕工、衛生防疫檢(jian)驗等行業和科研(yan)、教(jiao)學等部(bu)門。 |
