大氣(qi)粉(fen)塵顆(ke)粒(li)物(wu)綜合(he)采(cai)(cai)(cai)(cai)樣器(qi)種(zhong)類很多。按(an)使用場所(suo)可分(fen)為環境采(cai)(cai)(cai)(cai)樣器(qi)、室內(nei)采(cai)(cai)(cai)(cai)樣器(qi)（如(ru)工廠(chang)車間內(nei)使用的(de)采(cai)(cai)(cai)(cai)樣器(qi)）和污染源(yuan)采(cai)(cai)(cai)(cai)樣器(qi)（如(ru)煙囪(cong)采(cai)(cai)(cai)(cai)樣器(qi)），按(an)采(cai)(cai)(cai)(cai)集(ji)對象可分(fen)為氣(qi)體（包(bao)括蒸氣(qi)）采(cai)(cai)(cai)(cai)樣器(qi)和顆(ke)粒(li)物(wu)采(cai)(cai)(cai)(cai)樣器(qi)兩種(zhong)。另外還有一些(xie)特殊用途的(de)大氣(qi)采(cai)(cai)(cai)(cai)樣器(qi)，如(ru)同時采(cai)(cai)(cai)(cai)集(ji)氣(qi)體和顆(ke)粒(li)物(wu)的(de)采(cai)(cai)(cai)(cai)樣器(qi)，可采(cai)(cai)(cai)(cai)集(ji)大氣(qi)中(zhong)二氧化硫和顆(ke)粒(li)物(wu)，或氟化氫和顆(ke)粒(li)物(wu)等，便于研究(jiu)氣(qi)態和固態物(wu)質中(zhong)硫或氟的(de)相(xiang)互關系(xi)。以下就是小編對大氣(qi)粉(fen)塵顆(ke)粒(li)物(wu)綜合(he)采(cai)(cai)(cai)(cai)樣器(qi)的(de)操(cao)作技(ji)巧進行介紹。

大氣粉塵顆粒物綜合采樣器操作技巧
1、大氣采樣器(qi)在使(shi)用前(qian)，要為內置電(dian)(dian)(dian)(dian)(dian)源(yuan)充(chong)(chong)足電(dian)(dian)(dian)(dian)(dian)。充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時，電(dian)(dian)(dian)(dian)(dian)源(yuan)引線插(cha)入儀(yi)器(qi)背面的電(dian)(dian)(dian)(dian)(dian)源(yuan)切(qie)換插(cha)座中(zhong)，同時將(jiang)儀(yi)器(qi)面板上的功能開關(guan)撥至“C”位置，此時微電(dian)(dian)(dian)(dian)(dian)腦顯(xian)示(shi)窗口顯(xian)示(shi)“一(yi)、二、三”連續串動的標志(zhi)，說(shuo)明儀(yi)器(qi)正處于充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)狀態(tai)。一(yi)般(ban)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)需16小時左右，儀(yi)器(qi)內有(you)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)保護電(dian)(dian)(dian)(dian)(dian)路，不會(hui)發生過充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)顯(xian)現(xian)。
2、采樣時(shi)(shi)，在(zai)儀器進(jin)氣口接上過(guo)濾(lv)器，主(zhu)要(yao)是對空氣中(zhong)的(de)(de)灰塵等進(jin)行(xing)過(guo)濾(lv)；另在(zai)發生誤操作倒吸溶液時(shi)(shi)過(guo)濾(lv)膨脹，可以(yi)(yi)防(fang)止(zhi)溶液吸入(ru)泵體，以(yi)(yi)免泵體損壞。大氣粉(fen)塵顆粒(li)物綜合采樣器使用時(shi)(shi)間較長，也須及時(shi)(shi)更換濾(lv)塵泡塑(su)塊，以(yi)(yi)免臟物穿透濾(lv)塵泡塑(su)塊進(jin)入(ru)泵內影響泵的(de)(de)流量。 
3、檢查(cha)儀(yi)(yi)器的(de)可靠(kao)性(xing)(xing)，除(chu)檢驗有關(guan)技(ji)術指(zhi)標外，還需檢查(cha)鎘膜泵是否竄(cuan)氣(qi)。檢查(cha)時(shi)(shi)首先(xian)用手指(zhi)堵住儀(yi)(yi)器的(de)進氣(qi)口，觀(guan)察流(liu)(liu)量(liang)計的(de)轉(zhuan)(zhuan)子是否降至低處，如果流(liu)(liu)量(liang)計的(de)轉(zhuan)(zhuan)子繼續(xu)竄(cuan)動，表(biao)明(ming)鎘膜泵竄(cuan)氣(qi)，應及時(shi)(shi)進行檢修。若轉(zhuan)(zhuan)子停(ting)滯不(bu)動，表(biao)明(ming)儀(yi)(yi)器性(xing)(xing)能(neng)良好，工(gong)作流(liu)(liu)量(liang)指(zhi)示(shi)可靠(kao)。
4、若(ruo)操作中不慎倒(dao)吸(xi)酸堿溶液時，可使(shi)采(cai)樣器(qi)斷(duan)續吸(xi)入蒸餾水(shui)清洗幾次，再吸(xi)入無水(shui)乙(yi)醇(chun)，使(shi)儀(yi)器(qi)空載(zai)運轉半小時左(zuo)右，使(shi)乙(yi)醇(chun)充分排(pai)出。一般情況大氣粉塵顆粒(li)物綜合采(cai)樣器(qi)都能恢復正常(chang)工作指標(biao)。若(ruo)顆粒(li)或纖維(wei)(wei)等雜質(zhi)進入鎘(ge)膜泵內，經(jing)清洗后無法排(pai)除，應(ying)寄回本廠維(wei)(wei)護，或到本廠地點維(wei)(wei)護。
5、大氣粉(fen)塵(chen)顆粒物綜合采(cai)樣器自(zi)動(dong)采(cai)樣，首先按數碼開關(guan)鍵確定采(cai)樣時(shi)(shi)(shi)(shi)間，然后將功(gong)能(neng)選(xuan)擇(ze)開關(guan)撥至(zhi)“ON”位置，此時(shi)(shi)(shi)(shi)微電(dian)腦顯(xian)示(shi)(shi)(shi)窗口(kou)(kou)(kou)出現設(she)定的采(cai)樣時(shi)(shi)(shi)(shi)間，當時(shi)(shi)(shi)(shi)間數字連(lian)續跳動(dong)10次，并(bing)發(fa)出蜂鳴(ming)(ming)聲(sheng)時(shi)(shi)(shi)(shi)，儀器開始(shi)工(gong)作(zuo)。采(cai)樣時(shi)(shi)(shi)(shi)間結束后，微電(dian)腦顯(xian)示(shi)(shi)(shi)窗口(kou)(kou)(kou)顯(xian)示(shi)(shi)(shi)“000”標志(zhi)，同時(shi)(shi)(shi)(shi)伴有蜂鳴(ming)(ming)聲(sheng)，儀器自(zi)動(dong)停(ting)(ting)止工(gong)作(zuo)。如需長(chang)時(shi)(shi)(shi)(shi)間工(gong)作(zuo)，將功(gong)能(neng)選(xuan)擇(ze)開關(guan)撥至(zhi)“S”位置，此時(shi)(shi)(shi)(shi)儀器處(chu)于手(shou)動(dong)工(gong)作(zuo)狀態，微電(dian)腦顯(xian)示(shi)(shi)(shi)窗口(kou)(kou)(kou)顯(xian)示(shi)(shi)(shi)”ON“開機符號，停(ting)(ting)止采(cai)樣時(shi)(shi)(shi)(shi)，將功(gong)能(neng)選(xuan)擇(ze)開關(guan)撥至(zhi)”ON“位置，微電(dian)腦顯(xian)示(shi)(shi)(shi)窗口(kou)(kou)(kou)顯(xian)示(shi)(shi)(shi)”OF“停(ting)(ting)機標志(zhi)。

6、試機(ji)采(cai)用，準(zhun)備工(gong)(gong)作(zuo)就(jiu)緒后，大氣粉塵(chen)顆粒物綜合(he)采(cai)樣器將功能開(kai)關撥至(zhi)“ON”或(huo)者“S”位置，再調節流(liu)量(liang)(liang)調節閥，將流(liu)量(liang)(liang)調至(zhi)采(cai)樣所(suo)需設定的流(liu)量(liang)(liang)，儀器便開(kai)始工(gong)(gong)作(zuo)。
