特點(Features)
現(xiàn)代的用戶接口界面 Modern User Interface
智能的彩色觸摸屏用戶界面，能方便地直 接設定或編輯、存貯及調(diào)用方法，快速起動分析。圖示，*的動態(tài)圖形顯示,能清楚地展示有關樣品提取過程中各部分的動作狀態(tài)，使用戶對儀器運行過程一目了然。
An intuitive, color touch screen user interface provides instant access to system functionality. Set parameters, recall stored methodsstart sampling quickly. The modern screen graphical user interface displays a sampling process. And making user know well it.
中英文可選擇 ChineseEnglish are available 全流路自動泄漏測試 Leak Test 使分析質(zhì)量更為可靠。如圖所示，用戶選定泄漏測試，儀器將進入全流路泄漏測試（包括樣品瓶在內(nèi)的），zui大限度地保證儀器可靠性。This function will help user to complete the whole carrier gas system test with a vialget a high reliability. 動態(tài)和靜態(tài)任意選擇采用單針雙流路及氣路選擇技術，能很方便實現(xiàn)動態(tài)和靜態(tài)頂空功能。防止樣品高溫氧化功能。提供一種樣品反映動力學研究手段，對于一些特殊樣品，Purge模式為用戶提供了樣品處理前頂空瓶內(nèi)空氣置換，避免了樣品的變性，影響分析質(zhì)量。The Double holes in needlegas selecting provide dynamicstatic headspace methods. Employed the technique prevent from sample decomposition or oxidization. Employing the Purge mode, can sweep the air in vials with carrier gas. The mode is useful in kinetic studies. 高的樣品輸出特性High Sample Throughput 可存儲10個方法 
幾乎任何樣品中的揮發(fā)性化合物都能簡單、快速地用頂空氣相色譜分析，頂空進樣技術提供了對液相和固體樣品的無溶劑萃取，從而節(jié)約了時間并消除了其它樣品制備方法中可能出現(xiàn)的錯誤，如吸附和萃取。 Volatile compounds in almost any sample matrix canbe analyzed simplyquickly by headspace gas chromatography. Headspace sampling provides a method that extract sample of liquidsolid with a solvent-freeminimizes rework by eliminating many of the tediouserror-producing . The system compley rely on volatilization to separate the compounds from the sample matrix, so sample extraction, clean uppreconcentration are not necessary. 恒定模式和吹掃模式（ConstantPurge Mode） AutoHS提供了*的樣品輸出能力，40個樣品位的樣品盤和15個樣品位的加熱爐，對許多應用都可以進行無人干預操作。在Purge模式下，可以一次性上裝13個瓶進入爐內(nèi)，進行氣體置換。恒定模式（Constant Mode）使用優(yōu)化的樣品重疊模式，頂空的汽化平衡是在恒溫條件下獲得的，恒溫器可以同時容納12個樣品瓶，以確保在上一個樣品被分析完之前，準備好下一個樣品的分析。這一過程，大大節(jié)約了由于分析下一個樣品所需加熱恒溫平衡時間，也使樣品的重復性得到保證。提供樣品流路的同時，樣品輸出采用去活性襯管連接，消除了樣品間的污染。
AutoHS provides high sample throughput. Equipped with a 40-sample tray15 positions in the heating oven allowing unattended overnight operation for many applications. It can load 13 vials to be purged in the Purge Mode. In Constant Mode , automated constant heating time is employed with optimized sample overlapping for maximum sample throughput in the minimum amount of time. It can simultaneously thermostat up to 12 samples, ensuring that the next sample is always ready for analysis upon completion of the previous run. This adds up to a significant time savings since there is no need to wait for the next sample to heatget best reproducibility. A deactivated sampling path, from switch valve to transfer line, is standard on the AutoHS. The clean gas swept the sample path. 溫度漸進模式（Progressive Mode） 溫度漸進模式以一個較短的時間基數(shù)，對同等量含同樣組份的一系列樣品恒溫平衡時間以等差級數(shù)遞增，得到一組色譜數(shù)據(jù)，同一組分，當它在頂空達到平衡后，它的分壓是不隨時間變化的，平衡后所得到的色譜峰面積也就zui高。從而獲得一個的平衡時間。在這個模式運行過程中，儀器將自動選擇zui短的運行時間，即能從單個樣品恒溫平衡到多個樣品恒溫平衡的自動轉換。 In the Progressive Mode, the vials are thermostatted for an increasing time, representing a multiple of the first thermostatting time. It is used in the determination of the necessary equilibration time, where a number of vials containing the same sample are to be thermostated for increasing periods. Automatically optimized samples. 多次頂空模式（MHE mode）對于同一樣品瓶的多次頂空提取，得到多個樣品色譜圖，用于方法的開發(fā)和對特種樣品的分析。The technique requires multiple extractions from the sample vial. This is very useful for developing methodrunning special sample. 儀器接口 Input/Output Port 與各種氣相色譜儀連接，提供各種氣路樣品傳輸接口，電路輸入/輸出接口采用標準的信號接口，外部準備，啟動、停止，準備輸出， 運行輸出等。 Provided ports to connect with any gas chromatograph with a standard interface. They includes: Ready In, Start In, Stop In, Ready OutRun Out.
