如何提高自動進樣針進樣定量的重復性

對(dui)于現(xian)(xian)在(zai)(zai)的(de)氣相色譜(pu)分析來說，大(da)多會采(cai)用自(zi)動進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)針來代替(ti)人(ren)工手(shou)動進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)，不(bu)僅降低了(le)人(ren)工進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)的(de)誤(wu)差，也提(ti)升了(le)進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)速度和(he)效率(lv)。但是(shi)有時(shi)(shi)候在(zai)(zai)使用自(zi)動進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)針的(de)時(shi)(shi)候，會出(chu)現(xian)(xian)定量重復性(xing)不(bu)好(hao)的(de)現(xian)(xian)象，這(zhe)是(shi)為什么呢？1、對(dui)自(zi)動進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)針進(jin)(jin)(jin)(jin)行(xing)(xing)檢(jian)(jian)查(cha)。提(ti)高進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)定量重復性(xing)的(de)關(guan)鍵(jian)，就在(zai)(zai)于始終保持進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)操(cao)作(zuo)各個步驟的(de)重復性(xing)，要(yao)求自(zi)動進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)器有穩定且一(yi)致的(de)進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)性(xing)能。所以，一(yi)旦出(chu)現(xian)(xian)定量重復性(xing)不(bu)好(hao)的(de)問(wen)題，首先對(dui)自(zi)動進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)器進(jin)(jin)(jin)(jin)行(xing)(xing)檢(jian)(jian)查(cha)，看機(ji)器是(shi)否出(chu)現(xian)(xian)故障。2、對(dui)進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)針進(jin)(jin)(jin)(jin)行(xing)(xing)檢(jian)(jian)查(cha)。操(cao)作(zuo)人(ren)員在(zai)(zai)檢(jian)(jian)查(cha)了(le)自(zi)動進(jin)(jin)(jin)(jin)樣(yang)(yang)(yang)(yang)針的(de)物理運動*后，如(ru)果色譜(pu)峰靈(ling)敏度仍然無(wu)顯著改觀
