標準氣體

所謂標(biao)準(zhun)(zhun)(zhun)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)就是用(yong)(yong)(yong)來(lai)校正測(ce)量(liang)儀器、評價(jia)測(ce)定(ding)(ding)(ding)方法(fa)、給出未知樣品氣(qi)(qi)(qi)(qi)標(biao)準(zhun)(zhun)(zhun)值(zhi)的氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)。它分(fen)為調整零位用(yong)(yong)(yong)標(biao)準(zhun)(zhun)(zhun)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)（零位氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)）、監測(ce)環(huan)境用(yong)(yong)(yong)標(biao)準(zhun)(zhun)(zhun)氣(qi)(qi)(qi)(qi)、工(gong)業分(fen)析用(yong)(yong)(yong)標(biao)準(zhun)(zhun)(zhun)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)、醫i療儀器用(yong)(yong)(yong)標(biao)準(zhun)(zhun)(zhun)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)、可(ke)燃性氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)泄漏　用(yong)(yong)(yong)標(biao)準(zhun)(zhun)(zhun)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)、燃燒器尾氣(qi)(qi)(qi)(qi)用(yong)(yong)(yong)標(biao)準(zhun)(zhun)(zhun)氣(qi)(qi)(qi)(qi)體(ti)(ti)(ti)(ti)(ti)六大(da)類。　由于(yu)使(shi)用(yong)(yong)(yong)了標(biao)準(zhun)(zhun)(zhun)氣(qi)(qi)(qi)(qi)，所以即使(shi)在不同場所測(ce)　定(ding)(ding)(ding)，也具有相同測(ce)定(ding)(ding)(ding)值(zhi)。

標(biao)準(zhun)氣(qi)(qi)體(ti)應用范圍很廣，在(zai)(zai)化(hua)工(gong)(gong)(gong)(gong)(gong)、石(shi)油(you)(you)　冶(ye)金、機(ji)械、航天、電子(zi)、軍i工(gong)(gong)(gong)(gong)(gong)玻璃、陶(tao)瓷(ci)、　醫i藥(yao)醫i療、汽車(che)、光(guang)纖、激光(guang)、潛水(shui)、環(huan)保、切割(ge)、焊接、食品加(jia)工(gong)(gong)(gong)(gong)(gong)等工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)部門均使用大(da)量(liang)(liang)的(de)常(chang)用氣(qi)(qi)體(ti)和(he)特(te)種氣(qi)(qi)體(ti)。其中在(zai)(zai)石(shi)油(you)(you)化(hua)工(gong)(gong)(gong)(gong)(gong)　領域對(dui)標(biao)準(zhun)氣(qi)(qi)體(ti)的(de)需(xu)求量(liang)(liang)相對(dui)較大(da)。石(shi)油(you)(you)化(hua)工(gong)(gong)(gong)(gong)(gong)是(shi)我國四大(da)支柱產業(ye)(ye)(ye)之(zhi)一。我國乙烯(xi)工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)發展(zhan)迅速，已建和(he)在(zai)(zai)建乙烯(xi)工(gong)(gong)(gong)(gong)(gong)程　均已到位。在(zai)(zai)大(da)型石(shi)油(you)(you)化(hua)工(gong)(gong)(gong)(gong)(gong)裝置開車(che)、停車(che)　和(he)正常(chang)運行(xing)中需(xu)要幾(ji)十(shi)種純氣(qi)(qi)和(he)上百種多組分(fen)標(biao)準(zhun)混合氣(qi)(qi)，用來(lai)校(xiao)準(zhun)定標(biao)在(zai)(zai)線分(fen)析(xi)儀表及分(fen)析(xi)原料和(he)產品的(de)檢(jian)涮儀器。這對(dui)于穩(wen)定　運行(xing)和(he)提高產量(liang)(liang)是(shi)非常(chang)重(zhong)要的(de)。乙烯(xi)是(shi)石(shi)油(you)(you)化(hua)工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)重(zhong)要的(de)基礎原料，其產量(liang)(liang)和(he)技術水(shui)平(ping)是(shi)衡量(liang)(liang)一個國家(jia)石(shi)化(hua)工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)乃(nai)至整個工(gong)(gong)(gong)(gong)(gong)業(ye)(ye)(ye)水(shui)平(ping)的(de)重(zhong)要標(biao)志之(zhi)一。

容積法1、適用范圍靜態容積法適用于實驗室制備多種小、少量的標準氣體，壓力接近大氣壓力。2、所需設備配氣設備：氣瓶，氣瓶減壓閥門，定體積管，壓力計，真空泵。飽和法1、適用范圍飽和法法適用于易于冷凝的氣體和蒸汽。2、所需設備配氣設備：氣瓶，標準氣體價格，氣瓶減壓閥門，冷凝器，飽和器，恒溫控制器，壓力計，循環風機。流量法1、適用范圍流量比法法是動態配氣方法，是嚴格控制一定比例的組分氣體和釋稀釋氣體的流量，經混合而得到的標準氣體。2、所需設備氣瓶，氣瓶減壓閥門，單向閥，流量控制器，壓力表，標準氣體怎么樣，管道，機箱。

由于均勻性是考察同一瓶標準氣體在制備完以后，標準氣體，多長時間量值達到穩定，由有限次測定得到的平均值，在方法的不確定范圍內應該是不顯著的。如果差異是顯著的，標準氣體報價，這個因素就是標準氣體的不均勻性造成的。穩定性編輯前言標準物質是指:“具有足夠均勻并已經很好地確定某一種或多種特性的物質或材料， 用于校準儀器、評價測量方法或確定物質的量值。”標準氣體是氣體標準物質， 由于標準氣體具有一定的有效期， 因此，標準氣體的穩定性是配制和使用過程中的關鍵問題。
