DJ-200T型頂空進(jìn)樣器是上海金凱德分析儀器有限公司專為色譜分析中需要樣品制備而特制的一種高性能低成本的經(jīng)濟(jì)型進(jìn)樣器, 它利用頂空技術(shù)(氣體萃。獬朔彪s的樣品前處理過(guò)程, 可用于氣體、液體或者固體樣品中揮發(fā)性組份的定性、定量分析。具有方便、花費(fèi)少、易于自動(dòng)化的特點(diǎn)。
頂空進(jìn)樣器特點(diǎn):
■可加熱的氣密針套,確保樣品無(wú)稀釋、無(wú)冷凝
■靈敏度高,重現(xiàn)性佳
■*多可同時(shí)加熱六個(gè)樣品,效率高
■加熱箱支持多種規(guī)格的頂空瓶
■操作簡(jiǎn)單,可方便的連接國(guó)內(nèi)外各類型號(hào)的氣相色譜儀
頂空進(jìn)樣器應(yīng)用領(lǐng)域:
■法庭科學(xué):血、尿中醇、醛、酮等揮發(fā)性毒物的檢驗(yàn)
■交通安全:車(chē)輛駕駛?cè)藛T飲酒及醉酒駕車(chē)時(shí)血液中酒精含量值的檢驗(yàn)
■釀酒/食品行業(yè):啤酒中低沸點(diǎn)香味成分的測(cè)定;浸出油中的6#溶劑殘留量的檢測(cè)
■環(huán)境保護(hù):如江、河、湖等地表水及自來(lái)水中揮發(fā)性鹵代烴的測(cè)定
■制藥行業(yè):藥品中的殘留溶劑的檢測(cè)
■材料控制:飲料瓶中乙醛殘留量的檢測(cè)

The KAILING DJ-200T sampler for Head Space technique within your reach with a low cost and high precision level
The DJ-200T sampler is the first manual system for Static Head Space that allows the application of this technique in a quantitative manner.
Until now it was only possible to use the technique of Static Head Space with automatic equipment. This “equipment” has a high cost low versatility and complex operations. For this reason the Static Head Space technique has not been fully used in most laboratories.
The new DJ-200T sampler solves these problems making the technique available to all Gas Chromatography users in an economical and simple way.
