氮氣吹掃這(zhe)個是(shi)可(ke)以自(zi)己直接(jie)產生(sheng)氮氣還是(shi)需要連(lian)接(jie)氮氣鋼瓶(ping)，直接(jie)安個減壓閥嗎？

    氮氣吹(chui)干儀又稱為(wei)：氮氣濃縮(suo)裝(zhuang)置、氮氣吹(chui)掃儀，簡稱：氮吹(chui)儀、吹(chui)氮儀。

    現在市面上(shang)(shang)(shang)有:干(gan)式氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)和水(shui)浴氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)，干(gan)式氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)一般是由(you)鋁塊(kuai)加熱(re)，溫(wen)(wen)度(du)可(ke)以(yi)(yi)(yi)(yi)(yi)達到(dao)100度(du)以(yi)(yi)(yi)(yi)(yi)上(shang)(shang)(shang)，而且(qie)使(shi)用(yong)(yong)(yong)(yong)起(qi)來比較方便，水(shui)浴氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)是有水(shui)當介(jie)質加熱(re)的，這(zhe)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)溫(wen)(wen)度(du)在100度(du)以(yi)(yi)(yi)(yi)(yi)內，水(shui)浴氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)溫(wen)(wen)度(du)比較均勻。氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)的原理其工作(zuo)原理是通(tong)(tong)過將(jiang)(jiang)氮(dan)(dan)(dan)氣(qi)(qi)(qi)吹(chui)(chui)(chui)(chui)(chui)入加熱(re)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)試管(guan)內，使(shi)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)中(zhong)的溶劑快速(su)蒸(zheng)發、分(fen)離，因(yin)為(wei)氮(dan)(dan)(dan)氣(qi)(qi)(qi)一般不(bu)(bu)(bu)會和樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)反應(ying)，從而達到(dao)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)無氧濃(nong)縮的目的，保持樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)純。氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)的使(shi)用(yong)(yong)(yong)(yong)氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)安裝好(hao)后(hou)(hou)，底(di)盤(pan)支撐在恒溫(wen)(wen)水(shui)浴內，打開(kai)電(dian)源(yuan)，設定溫(wen)(wen)度(du)，開(kai)始加熱(re)。提升氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)，將(jiang)(jiang)需要蒸(zheng)發濃(nong)縮的樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)分(fen)別安放在樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)定位(wei)架上(shang)(shang)(shang)，并由(you)托(tuo)盤(pan)托(tuo)起(qi)，其中(zhong)托(tuo)盤(pan)和定位(wei)架高低可(ke)根(gen)據(ju)培(pei)訓樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)試管(guan)的大小調(diao)整。長沙巴躍儀(yi)(yi)(yi)(yi)器小鄧教您：打開(kai)流(liu)量(liang)計針(zhen)(zhen)閥(fa)(fa)，氮(dan)(dan)(dan)氣(qi)(qi)(qi)經(jing)流(liu)量(liang)計和輸氣(qi)(qi)(qi)管(guan)到(dao)達配(pei)氣(qi)(qi)(qi)盤(pan)，配(pei)氣(qi)(qi)(qi)后(hou)(hou)送往(wang)各(ge)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)位(wei)上(shang)(shang)(shang)方的針(zhen)(zhen)閥(fa)(fa)管(guan)(安裝在配(pei)氣(qi)(qi)(qi)盤(pan)上(shang)(shang)(shang))。然后(hou)(hou)，通(tong)(tong)過網(wang)校調(diao)節(jie)針(zhen)(zhen)閥(fa)(fa)管(guan)針(zhen)(zhen)閥(fa)(fa)，氮(dan)(dan)(dan)氣(qi)(qi)(qi)經(jing)針(zhen)(zhen)閥(fa)(fa)管(guan)和針(zhen)(zhen)頭吹(chui)(chui)(chui)(chui)(chui)向液體樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)試管(guan)，可(ke)通(tong)(tong)過調(diao)整鎖緊螺(luo)母可(ke)以(yi)(yi)(yi)(yi)(yi)上(shang)(shang)(shang)下(xia)(xia)滑(hua)動針(zhen)(zhen)閥(fa)(fa)管(guan)，調(diao)整針(zhen)(zhen)頭高度(du)，以(yi)(yi)(yi)(yi)(yi)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)表面吹(chui)(chui)(chui)(chui)(chui)起(qi)波(bo)紋，樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)又不(bu)(bu)(bu)濺起(qi)為(wei)好(hao)。氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)應(ying)用(yong)(yong)(yong)(yong)領域(yu)：農(nong)殘分(fen)析：如蔬菜、水(shui)果、谷物(wu)、植物(wu)組(zu)織;環(huan)境分(fen)析：如飲引用(yong)(yong)(yong)(yong)水(shui)、地(di)下(xia)(xia)水(shui)和污染水(shui)水(shui)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang);生(sheng)物(wu)分(fen)析：如激素(su)分(fen)析、液相、氣(qi)(qi)(qi)相及(ji)質譜(pu)分(fen)析中(zhong)的樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)制備;食品(pin)(pin)(pin)飲料：如牛奶(nai)、酒(jiu)、啤酒(jiu)等;制藥(yao)(yao)(yao)藥(yao)(yao)(yao)檢：如中(zhong)藥(yao)(yao)(yao)制藥(yao)(yao)(yao)、藥(yao)(yao)(yao)物(wu)篩選。氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)使(shi)用(yong)(yong)(yong)(yong)注意事(shi)項：(1)不(bu)(bu)(bu)將(jiang)(jiang)氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)用(yong)(yong)(yong)(yong)于燃(ran)點低于100℃的物(wu)質。(2)使(shi)用(yong)(yong)(yong)(yong)氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)時,應(ying)當保護手和眼睛(jing)。氮(dan)(dan)(dan)氣(qi)(qi)(qi)吹(chui)(chui)(chui)(chui)(chui)掃儀(yi)(yi)(yi)(yi)(3)氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi)應(ying)當在通(tong)(tong)風(feng)櫥中(zhong)使(shi)用(yong)(yong)(yong)(yong),以(yi)(yi)(yi)(yi)(yi)保證通(tong)(tong)風(feng)良好(hao)。(4)加熱(re)時不(bu)(bu)(bu)要移動氮(dan)(dan)(dan)吹(chui)(chui)(chui)(chui)(chui)儀(yi)(yi)(yi)(yi),以(yi)(yi)(yi)(yi)(yi)防燙傷。(5)用(yong)(yong)(yong)(yong)三線接地(di)電(dian)源(yuan)使(shi)用(yong)(yong)(yong)(yong)。(6)當打開(kai)氮(dan)(dan)(dan)氣(qi)(qi)(qi)氣(qi)(qi)(qi)閥(fa)(fa)要緩慢，不(bu)(bu)(bu)要一下(xia)(xia)壓(ya)力過大，會把(ba)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品(pin)(pin)(pin)吹(chui)(chui)(chui)(chui)(chui)出(chu)。減(jian)壓(ya)閥(fa)(fa)，可(ke)以(yi)(yi)(yi)(yi)(yi)的，控(kong)制速(su)度(du)控(kong)制壓(ya)力，不(bu)(bu)(bu)觸(chu)碰(peng)液面這(zhe)么吹(chui)(c
