氦離子化檢測器的*能優(yōu)勢
VICI PDDs (脈沖放電檢測器)利用在氦氣中穩(wěn)定的、低能耗、脈沖DC放電作為離子源。過柱的洗脫液沿著從放電區(qū)發(fā)出的氦氣流相反的方向流動,被氦氣放電發(fā)出的光子離子化。斜線電極聚焦發(fā)生的電子到收集電極,在那改變穩(wěn)定電流,電流再被量化為檢測器輸出。*能與帶常規(guī)放射源的檢測器相當(dāng)或更優(yōu)。 在氦氣光化電離模式下的PDD為石油化學(xué)或煉油廠環(huán)境的火焰離子檢測器一個(gè)極好的替代產(chǎn)品,而它火焰和氫氣的使用存在問題。另外,當(dāng)氦氣放電氣體與適當(dāng)?shù)亩?氣體如氬、氪或氙(決定于期望的截止點(diǎn))混合時(shí),PDD 可作為特殊光化電離檢測器用于脂肪族化合物、芳香族、胺以及其它物質(zhì)選擇檢測。
使用PDD(脈沖放電檢測器)測定呼吸用氧氣中的氣體和輕烴雜質(zhì)PDD檢測器為通用型、非破壞*檢測器,所以在測定氣體中無機(jī)和有機(jī)組分時(shí),靈敏度高,測定簡單快速。下表中為測定化合物的允許值。
注意:
HID最突出的*能特征是:①級的靈敏度的通用*的響應(yīng);②*作中必須小心控制污染;③常有異常響應(yīng)出現(xiàn)。此三特征是相互聯(lián)系的,且均與檢測條件密切相關(guān)。載氣純度、色譜柱流失和系統(tǒng)的氣密*等均是通過雜質(zhì)污染方式影響靈敏度;極化電壓、載氣流速和氣密*通過靈敏度變化產(chǎn)生正常和異常響應(yīng)等。下將討論這些檢測條件的選擇,從中加深對*能特征的理解。
載氣純度和流速載氣純度對HID的響應(yīng)起著十分重要的作用。載氣純度低,噪聲大、靈敏度低、線*范圍窄。
應(yīng)用 HID廣泛用于其他氣相色譜檢測器難以檢測的化合物(如無機(jī)氣體、全氟碳、水、甲酸和甲醛等)的痕量檢測。如高純氣中痕量雜質(zhì)的分析、氣體和液體樣品中痕量水的檢測、某些芳香族化合物和空氣中某些污染物的直接測定、以及氣相色譜裂解產(chǎn)物的分析等。
