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)價(jia)是表示有(you)機物中(zhong)所(suo)含游離酸(suan)數量多少的(de)(de)(de)(de)一種形式。油脂(zhi)酸(suan)價(jia)是指(zhi)中(zhong)和一克油脂(zhi)中(zhong)游離脂(zhi)肪酸(suan)所(suo)需(xu)氫氧化鉀的(de)(de)(de)(de)毫克數。它既(ji)是油脂(zhi)的(de)(de)(de)(de)一項(xiang)質(zhi)量指(zhi)標(biao)，也是食(shi)用油脂(zhi)的(de)(de)(de)(de)一項(xiang)食(shi)品(pin)衛生指(zhi)標(biao)。新鮮的(de)(de)(de)(de)或(huo)(huo)精制(zhi)油脂(zhi)的(de)(de)(de)(de)酸(suan)價(jia)都較低，因(yin)儲存或(huo)(huo)加(jia)工不當，都會使(shi)酸(suan)價(jia)增高。因(yin)此，只(zhi)有(you)加(jia)強油脂(zhi)酸(suan)價(jia)的(de)(de)(de)(de)測(ce)定，才能(neng)了解產品(pin)的(de)(de)(de)(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 繼開發 DP-YUS — 3 加強型(xing)(xing)酸(suan)價快速(su)測(ce)(ce)定(ding)(ding)(ding)儀(yi)（半(ban)自動(dong)）之后，又成(cheng)功地(di)(di)(di)研制(zhi)了(le)全(quan)自動(dong)酸(suan)測(ce)(ce)定(ding)(ding)(ding)儀(yi)。該儀(yi)器克服了(le)用(yong)(yong)(yong)肉(rou)眼(yan)判(pan)(pan)(pan)斷滴定(ding)(ding)(ding)終(zhong)點(dian)的(de)(de)缺陷，從電(dian)(dian)(dian)路到電(dian)(dian)(dian)化分(fen)析操作(zuo)都做(zuo)(zuo)了(le)全(quan)面更新設計(ji)。數顯(xian)器采用(yong)(yong)(yong)高亮度(du)的(de)(de)計(ji)數器，既方便(bian)了(le)觀察(cha)，又提(ti)(ti)高了(le)計(ji)數精(jing)度(du)。*“電(dian)(dian)(dian)子指(zhi)示劑”進行終(zhong)點(dian)判(pan)(pan)(pan)定(ding)(ding)(ding)，使(shi)儀(yi)器能(neng)檢測(ce)(ce)到滴定(ding)(ding)(ding)全(quan)過程，并(bing)能(neng)準(zhun)確(que)地(di)(di)(di)觀察(cha)到滴定(ding)(ding)(ding)的(de)(de)突躍點(dian)，測(ce)(ce)繪(hui)出(chu)完(wan)整的(de)(de)滴定(ding)(ding)(ding)曲(qu)線。我們還成(cheng)功地(di)(di)(di)將感測(ce)(ce)電(dian)(dian)(dian)極(ji)和參比(bi)電(dian)(dian)(dian)極(ji)微型(xing)(xing)化，并(bing)精(jing)心(xin)地(di)(di)(di)與電(dian)(dian)(dian)解(jie)極(ji)板復(fu)合在(zai)(zai)一(yi)支(zhi)電(dian)(dian)(dian)極(ji)桿上，使(shi)測(ce)(ce)試更為方便(bian)簡單。我們經過反(fan)復(fu)實驗，將電(dian)(dian)(dian)解(jie)液(ye)配(pei)方進行了(le)改進使(shi)其(qi)性(xing)能(neng)更為優(you)異，即使(shi)在(zai)(zai)冬季低溫條件(jian)下也(ye)能(neng)油脂(zhi)迅速(su)溶(rong)(rong)解(jie)，保(bao)證了(le)測(ce)(ce)定(ding)(ding)(ding)的(de)(de)精(jing)度(du)。，因本儀(yi)器不(bu)使(shi)用(yong)(yong)(yong)化學指(zhi)示劑判(pan)(pan)(pan)定(ding)(ding)(ding)終(zhong)點(dian)，在(zai)(zai)深(shen)色(se)油脂(zhi)的(de)(de)測(ce)(ce)定(ding)(ding)(ding)中(zhong)更能(neng)顯(xian)示出(chu)其(qi)優(you)越(yue)性(xing)。它(ta)能(neng)準(zhun)確(que)地(di)(di)(di)提(ti)(ti)供(gong)(gong)客觀判(pan)(pan)(pan)定(ding)(ding)(ding)終(zhong)點(dian)的(de)(de)手(shou)段，而且不(bu)需(xu)配(pei)制(zhi)和標(biao)定(ding)(ding)(ding)標(biao)準(zhun)堿(jian)(jian)溶(rong)(rong)液(ye)，不(bu)用(yong)(yong)(yong)國標(biao)法(fa)所判(pan)(pan)(pan)定(ding)(ding)(ding)終(zhong)點(dian)，在(zai)(zai)深(shen)色(se)油脂(zhi)的(de)(de)測(ce)(ce)定(ding)(ding)(ding)中(zhong)更能(neng)顯(xian)示出(chu)其(qi)優(you)越(yue)性(xing)。它(ta)能(neng)準(zhun)確(que)地(di)(di)(di)提(ti)(ti)供(gong)(gong)客觀判(pan)(pan)(pan)定(ding)(ding)(ding)終(zhong)點(dian)的(de)(de)手(shou)段，而且不(bu)需(xu)配(pei)制(zhi)和標(biao)定(ding)(ding)(ding)標(biao)準(zhun)堿(jian)(jian)溶(rong)(rong)液(ye)，不(bu)用(yong)(yong)(yong)國標(biao)法(fa)所判(pan)(pan)(pan)定(ding)(ding)(ding)終(zhong)點(dian)，在(zai)(zai)深(shen)色(se)油脂(zhi)的(de)(de)測(ce)(ce)定(ding)(ding)(ding)中(zhong)更能(neng)顯(xian)示出(chu)其(qi)優(you)越(yue)性(xing)。它(ta)能(neng)準(zhun)確(que)地(di)(di)(di)提(ti)(ti)供(gong)(gong)客觀判(pan)(pan)(pan)定(ding)(ding)(ding)終(zhong)點(dian)的(de)(de)手(shou)段，而且不(bu)需(xu)配(pei)制(zhi)和標(biao)定(ding)(ding)(ding)標(biao)準(zhun)堿(jian)(jian)溶(rong)(rong)液(ye)，不(bu)用(yong)(yong)(yong)國標(biao)法(fa)所使(shi)用(yong)(yong)(yong)大(da)量的(de)(de)醚做(zuo)(zuo)溶(rong)(rong)劑，因此(ci)本儀(yi)器具有重現性(xing)好，無毒害，費用(yong)(yong)(yong)省、操作(zuo)簡便(bian)、易于掌握和可用(yong)(yong)(yong)于流動(dong)檢測(ce)(ce)等(deng)優(you)點(dian)，在(zai)(zai)幾分(fen)鐘(zhong)內直接顯(xian)示測(ce)(ce)定(ding)(ding)(ding)結果。 本儀(yi)器主(zhu)要(yao)用(yong)于(yu)各種植物(wu)油(you)脂(zhi)、動物(wu)油(you)脂(zhi)的酸(suan)(suan)價(jia)測定，經專(zhuan)項調試后也可用(yong)于(yu)大(da)米、小麥粉、牛(niu)奶、酒類、醬油(you)等(deng)(deng)的酸(suan)(suan)度或總酸(suan)(suan)度的測定。本儀(yi)器可廣泛(fan)用(yong)于(yu)糧(liang)油(you)、食品(pin)、發酵、輕(qing)工、衛生防疫檢驗等(deng)(deng)行業和科(ke)研、教(jiao)學等(deng)(deng)部(bu)門。 |
