1、樣品的稱樣量

       樣品稱樣量不同,其所含的CS量就存在差別,導致分析結果落在儀器校正曲線上的區域不同。由于儀器線性范圍所限,這種校正區域的差異會造成分析結果的波動,尤其在分析儀器的上、下限附近時這種影響表現更為突出。

2、助溶劑的加入量

       影響分析結果穩定性的另一個因素是助溶劑的加入量,在分析低含量樣品時該影響非常突出。例如分析碳硫質量分數小于15μg/g的樣品時,分別加入1.5g2g助溶劑(助溶劑中碳硫質量分數分別為≤8μg/g,≤5μg/g),因為助溶劑的加入量通常不參與分析結果計算,因此兩次分析之間就引入了0.5g助溶劑所含碳硫量的波動。假定助溶劑中碳硫含量均為3μg/g,樣品稱樣量為0.5g,由于助溶劑的加入量不同 就引入了3μg/g的偏差。

4、坩堝

       坩堝的空白一直是碳硫分析人員關注的熱點。未經處理的坩堝,空白從10-100μg/g不等。預處理過程條件設置得當,坩堝空白可降至1μg/g以下。試驗證明,預處理時間長短和溫度高低對獲得坩堝穩定的地空白至關重要。例如,經800℃烘燒4h后的坩堝,用于分析鋼樣,得到的結果波動很大。而經1100℃烘燒4h后的坩堝,坩堝空白可降至1μg/g以下。

       因此,坩堝使用前一定要進行預處理,并控制合適的烘燒溫度和時間,一般建議在馬弗爐中1100℃下烘燒4h,從而最大程度降低坩堝空白對分析結果穩定性的影響。

7、溫度

       溫度對分析結果穩定性的影響主要體現在3個方面。首先,灰塵過濾器的溫度影響,在灰塵量相同的情況下,溫度越高,其吸附效果越差;其次,氣體分析的基礎離不開氣體狀態方程,紅外分析系統恒溫控制的溫度不同,會造成分析氣體體積的變化,從而造成一定量的分析氣體在不同溫度下通過固定長度洪外池的時間差;另外,紅外分析系統恒溫控制溫度的不同,會造成紅外光源的發射光強的波動以及熱釋電檢測器的輸出的差異,從而影響分析結果的穩定性。一般儀器都會配備這些部位的恒溫控制,在分析過程中應隨時監測恒溫控制效果,避免溫度造成的影響。
