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(shi)(shi)表示有機(ji)物中所含(han)游離(li)酸(suan)(suan)(suan)數量多少的(de)(de)一(yi)種形式。油(you)脂(zhi)酸(suan)(suan)(suan)價是(shi)(shi)指(zhi)(zhi)中和一(yi)克油(you)脂(zhi)中游離(li)脂(zhi)肪酸(suan)(suan)(suan)所需氫(qing)氧(yang)化鉀的(de)(de)毫克數。它既是(shi)(shi)油(you)脂(zhi)的(de)(de)一(yi)項質量指(zhi)(zhi)標，也是(shi)(shi)食(shi)用(yong)油(you)脂(zhi)的(de)(de)一(yi)項食(shi)品(pin)衛生指(zhi)(zhi)標。新鮮的(de)(de)或精制油(you)脂(zhi)的(de)(de)酸(suan)(suan)(suan)價都較低，因儲存(cun)或加(jia)工不當，都會(hui)使酸(suan)(suan)(suan)價增(zeng)高。因此，只有加(jia)強油(you)脂(zhi)酸(suan)(suan)(suan)價的(de)(de)測定，才能了(le)解產品(pin)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(ji)開發 DP-YUS — 3 加強型酸價快(kuai)速(su)測(ce)(ce)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)儀(yi)(yi)(yi)（半自(zi)動）之后，又(you)成功(gong)地(di)(di)(di)研(yan)制(zhi)(zhi)了(le)(le)(le)全(quan)自(zi)動酸測(ce)(ce)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)儀(yi)(yi)(yi)。該儀(yi)(yi)(yi)器(qi)克服(fu)了(le)(le)(le)用(yong)肉(rou)眼判(pan)斷(duan)滴(di)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)終點(dian)(dian)的(de)(de)(de)(de)缺陷，從(cong)電(dian)(dian)(dian)(dian)路到電(dian)(dian)(dian)(dian)化(hua)分析操(cao)作都做了(le)(le)(le)全(quan)面更(geng)(geng)(geng)新設計(ji)。數(shu)顯(xian)(xian)(xian)器(qi)采用(yong)高亮度的(de)(de)(de)(de)計(ji)數(shu)器(qi)，既(ji)方(fang)便(bian)了(le)(le)(le)觀(guan)(guan)察(cha)，又(you)提(ti)高了(le)(le)(le)計(ji)數(shu)精(jing)度。*“電(dian)(dian)(dian)(dian)子指示(shi)(shi)劑(ji)”進(jin)行(xing)終點(dian)(dian)判(pan)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)，使(shi)儀(yi)(yi)(yi)器(qi)能(neng)(neng)檢測(ce)(ce)到滴(di)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)全(quan)過程，并(bing)能(neng)(neng)準(zhun)(zhun)確(que)(que)地(di)(di)(di)觀(guan)(guan)察(cha)到滴(di)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)的(de)(de)(de)(de)突(tu)躍點(dian)(dian)，測(ce)(ce)繪(hui)出(chu)完整的(de)(de)(de)(de)滴(di)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)曲線。我們(men)還成功(gong)地(di)(di)(di)將(jiang)感測(ce)(ce)電(dian)(dian)(dian)(dian)極(ji)和(he)參比(bi)電(dian)(dian)(dian)(dian)極(ji)微型化(hua)，并(bing)精(jing)心地(di)(di)(di)與電(dian)(dian)(dian)(dian)解極(ji)板復合在(zai)一(yi)支(zhi)電(dian)(dian)(dian)(dian)極(ji)桿上，使(shi)測(ce)(ce)試更(geng)(geng)(geng)為方(fang)便(bian)簡(jian)單(dan)。我們(men)經過反復實(shi)驗，將(jiang)電(dian)(dian)(dian)(dian)解液(ye)配方(fang)進(jin)行(xing)了(le)(le)(le)改進(jin)使(shi)其(qi)(qi)(qi)性能(neng)(neng)更(geng)(geng)(geng)為優異，即使(shi)在(zai)冬季低溫條(tiao)件下也能(neng)(neng)油(you)脂(zhi)迅速(su)溶解，保(bao)證了(le)(le)(le)測(ce)(ce)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)的(de)(de)(de)(de)精(jing)度。，因(yin)本儀(yi)(yi)(yi)器(qi)不使(shi)用(yong)化(hua)學(xue)指示(shi)(shi)劑(ji)判(pan)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)終點(dian)(dian)，在(zai)深色(se)油(you)脂(zhi)的(de)(de)(de)(de)測(ce)(ce)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)中(zhong)更(geng)(geng)(geng)能(neng)(neng)顯(xian)(xian)(xian)示(shi)(shi)出(chu)其(qi)(qi)(qi)優越性。它能(neng)(neng)準(zhun)(zhun)確(que)(que)地(di)(di)(di)提(ti)供客(ke)觀(guan)(guan)判(pan)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)終點(dian)(dian)的(de)(de)(de)(de)手段(duan)，而且(qie)不需配制(zhi)(zhi)和(he)標(biao)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)標(biao)準(zhun)(zhun)堿(jian)溶液(ye)，不用(yong)國標(biao)法所判(pan)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)終點(dian)(dian)，在(zai)深色(se)油(you)脂(zhi)的(de)(de)(de)(de)測(ce)(ce)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)中(zhong)更(geng)(geng)(geng)能(neng)(neng)顯(xian)(xian)(xian)示(shi)(shi)出(chu)其(qi)(qi)(qi)優越性。它能(neng)(neng)準(zhun)(zhun)確(que)(que)地(di)(di)(di)提(ti)供客(ke)觀(guan)(guan)判(pan)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)終點(dian)(dian)的(de)(de)(de)(de)手段(duan)，而且(qie)不需配制(zhi)(zhi)和(he)標(biao)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)標(biao)準(zhun)(zhun)堿(jian)溶液(ye)，不用(yong)國標(biao)法所判(pan)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)終點(dian)(dian)，在(zai)深色(se)油(you)脂(zhi)的(de)(de)(de)(de)測(ce)(ce)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)中(zhong)更(geng)(geng)(geng)能(neng)(neng)顯(xian)(xian)(xian)示(shi)(shi)出(chu)其(qi)(qi)(qi)優越性。它能(neng)(neng)準(zhun)(zhun)確(que)(que)地(di)(di)(di)提(ti)供客(ke)觀(guan)(guan)判(pan)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)終點(dian)(dian)的(de)(de)(de)(de)手段(duan)，而且(qie)不需配制(zhi)(zhi)和(he)標(biao)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)標(biao)準(zhun)(zhun)堿(jian)溶液(ye)，不用(yong)國標(biao)法所使(shi)用(yong)大量(liang)的(de)(de)(de)(de)醚做溶劑(ji)，因(yin)此(ci)本儀(yi)(yi)(yi)器(qi)具有重現性好(hao)，無毒害，費用(yong)省、操(cao)作簡(jian)便(bian)、易于掌握(wo)和(he)可用(yong)于流動檢測(ce)(ce)等優點(dian)(dian)，在(zai)幾分鐘內直接顯(xian)(xian)(xian)示(shi)(shi)測(ce)(ce)定(ding)(ding)(ding)(ding)(ding)(ding)(ding)結果(guo)。 本(ben)儀器主要用于各(ge)種植(zhi)物油脂(zhi)、動物油脂(zhi)的酸(suan)價測(ce)定，經專(zhuan)項調試后(hou)也可用于大米(mi)、小麥粉、牛奶、酒類、醬油等(deng)(deng)(deng)的酸(suan)度(du)或(huo)總酸(suan)度(du)的測(ce)定。本(ben)儀器可廣(guang)泛(fan)用于糧(liang)油、食品、發酵、輕工(gong)、衛生防疫檢驗等(deng)(deng)(deng)行業(ye)和科研、教學(xue)等(deng)(deng)(deng)部門。 |
