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 酸價(jia)(jia)是(shi)(shi)表示有機物中所含游離酸數量多(duo)少的(de)(de)一種形式。油(you)(you)(you)(you)脂(zhi)(zhi)酸價(jia)(jia)是(shi)(shi)指(zhi)中和一克油(you)(you)(you)(you)脂(zhi)(zhi)中游離脂(zhi)(zhi)肪酸所需氫氧化鉀的(de)(de)毫克數。它(ta)既是(shi)(shi)油(you)(you)(you)(you)脂(zhi)(zhi)的(de)(de)一項質量指(zhi)標(biao)，也是(shi)(shi)食(shi)用油(you)(you)(you)(you)脂(zhi)(zhi)的(de)(de)一項食(shi)品衛(wei)生指(zhi)標(biao)。新(xin)鮮(xian)的(de)(de)或精制油(you)(you)(you)(you)脂(zhi)(zhi)的(de)(de)酸價(jia)(jia)都較(jiao)低，因(yin)儲存或加工不當(dang)，都會使(shi)酸價(jia)(jia)增高。因(yin)此，只(zhi)有加強(qiang)油(you)(you)(you)(you)脂(zhi)(zhi)酸價(jia)(jia)的(de)(de)測定，才(cai)能(neng)了解產(chan)品的(de)(de)質量。 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 加強型酸價快(kuai)速測(ce)定(ding)(ding)(ding)儀(yi)(yi)（半自(zi)動(dong)(dong)）之后，又成功地(di)(di)(di)研制(zhi)(zhi)了(le)(le)全(quan)自(zi)動(dong)(dong)酸測(ce)定(ding)(ding)(ding)儀(yi)(yi)。該(gai)儀(yi)(yi)器克服了(le)(le)用肉(rou)眼判(pan)(pan)(pan)斷滴(di)定(ding)(ding)(ding)終(zhong)點(dian)的(de)(de)(de)缺陷(xian)，從電(dian)路(lu)到電(dian)化(hua)分(fen)析操作都做了(le)(le)全(quan)面更(geng)新設(she)計(ji)。數顯器采(cai)用高亮度(du)(du)的(de)(de)(de)計(ji)數器，既方(fang)便了(le)(le)觀(guan)察，又提高了(le)(le)計(ji)數精(jing)度(du)(du)。*“電(dian)子指示劑(ji)”進(jin)行終(zhong)點(dian)判(pan)(pan)(pan)定(ding)(ding)(ding)，使儀(yi)(yi)器能(neng)(neng)檢測(ce)到滴(di)定(ding)(ding)(ding)全(quan)過程，并能(neng)(neng)準(zhun)(zhun)(zhun)確地(di)(di)(di)觀(guan)察到滴(di)定(ding)(ding)(ding)的(de)(de)(de)突躍(yue)點(dian)，測(ce)繪出(chu)完整(zheng)的(de)(de)(de)滴(di)定(ding)(ding)(ding)曲線。我們(men)還成功地(di)(di)(di)將(jiang)感測(ce)電(dian)極(ji)和參比電(dian)極(ji)微型化(hua)，并精(jing)心地(di)(di)(di)與電(dian)解(jie)極(ji)板復合在(zai)一(yi)支電(dian)極(ji)桿上(shang)，使測(ce)試(shi)更(geng)為(wei)方(fang)便簡(jian)單(dan)。我們(men)經過反(fan)復實驗，將(jiang)電(dian)解(jie)液配(pei)方(fang)進(jin)行了(le)(le)改進(jin)使其(qi)性(xing)能(neng)(neng)更(geng)為(wei)優(you)(you)異(yi)，即使在(zai)冬季(ji)低溫(wen)條件下也能(neng)(neng)油脂迅速溶解(jie)，保證了(le)(le)測(ce)定(ding)(ding)(ding)的(de)(de)(de)精(jing)度(du)(du)。，因本儀(yi)(yi)器不(bu)使用化(hua)學指示劑(ji)判(pan)(pan)(pan)定(ding)(ding)(ding)終(zhong)點(dian)，在(zai)深(shen)(shen)色油脂的(de)(de)(de)測(ce)定(ding)(ding)(ding)中更(geng)能(neng)(neng)顯示出(chu)其(qi)優(you)(you)越性(xing)。它(ta)(ta)能(neng)(neng)準(zhun)(zhun)(zhun)確地(di)(di)(di)提供(gong)客(ke)觀(guan)判(pan)(pan)(pan)定(ding)(ding)(ding)終(zhong)點(dian)的(de)(de)(de)手(shou)(shou)段，而(er)(er)且(qie)不(bu)需(xu)配(pei)制(zhi)(zhi)和標(biao)定(ding)(ding)(ding)標(biao)準(zhun)(zhun)(zhun)堿溶液，不(bu)用國標(biao)法所判(pan)(pan)(pan)定(ding)(ding)(ding)終(zhong)點(dian)，在(zai)深(shen)(shen)色油脂的(de)(de)(de)測(ce)定(ding)(ding)(ding)中更(geng)能(neng)(neng)顯示出(chu)其(qi)優(you)(you)越性(xing)。它(ta)(ta)能(neng)(neng)準(zhun)(zhun)(zhun)確地(di)(di)(di)提供(gong)客(ke)觀(guan)判(pan)(pan)(pan)定(ding)(ding)(ding)終(zhong)點(dian)的(de)(de)(de)手(shou)(shou)段，而(er)(er)且(qie)不(bu)需(xu)配(pei)制(zhi)(zhi)和標(biao)定(ding)(ding)(ding)標(biao)準(zhun)(zhun)(zhun)堿溶液，不(bu)用國標(biao)法所判(pan)(pan)(pan)定(ding)(ding)(ding)終(zhong)點(dian)，在(zai)深(shen)(shen)色油脂的(de)(de)(de)測(ce)定(ding)(ding)(ding)中更(geng)能(neng)(neng)顯示出(chu)其(qi)優(you)(you)越性(xing)。它(ta)(ta)能(neng)(neng)準(zhun)(zhun)(zhun)確地(di)(di)(di)提供(gong)客(ke)觀(guan)判(pan)(pan)(pan)定(ding)(ding)(ding)終(zhong)點(dian)的(de)(de)(de)手(shou)(shou)段，而(er)(er)且(qie)不(bu)需(xu)配(pei)制(zhi)(zhi)和標(biao)定(ding)(ding)(ding)標(biao)準(zhun)(zhun)(zhun)堿溶液，不(bu)用國標(biao)法所使用大量的(de)(de)(de)醚做溶劑(ji)，因此本儀(yi)(yi)器具有重現性(xing)好(hao)，無毒(du)害(hai)，費用省(sheng)、操作簡(jian)便、易于掌握和可用于流動(dong)(dong)檢測(ce)等優(you)(you)點(dian)，在(zai)幾分(fen)鐘內直接顯示測(ce)定(ding)(ding)(ding)結果。 本(ben)儀(yi)器主要用(yong)(yong)于各種植物(wu)油(you)脂(zhi)、動物(wu)油(you)脂(zhi)的酸(suan)價測定，經專項調試后也可用(yong)(yong)于大米、小麥粉、牛奶(nai)、酒類、醬油(you)等的酸(suan)度或總酸(suan)度的測定。本(ben)儀(yi)器可廣泛用(yong)(yong)于糧油(you)、食(shi)品、發酵、輕工、衛生防疫檢(jian)驗等行業和科研、教學等部門。 |
