中英文可選擇 ChineseEnglish are available 全流路自動(dòng)泄漏測(cè)試 Leak Test 使分析質(zhì)量更為可靠。如圖所示，用戶選定泄漏測(cè)試，儀器將進(jìn)入全流路泄漏測(cè)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(dòng)態(tài)和靜態(tài)任意選擇采用單針雙流路及氣路選擇技術(shù)，能很方便實(shí)現(xiàn)動(dòng)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(dòng)力學(xué)研究手段，對(duì)于一些特殊樣品，Purge模式為用戶提供了樣品處理前頂空瓶?jī)?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(chǔ)10個(gè)方法 
幾乎任何樣品中的揮發(fā)性化合物都能簡(jiǎn)單、快速地用頂空氣相色譜分析，頂空進(jìn)樣技術(shù)提供了對(duì)液相和固體樣品的無溶劑萃取，從而節(jié)約了時(shí)間并消除了其它樣品制備方法中可能出現(xiàn)的錯(cuò)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(gè)樣品位的樣品盤和15個(gè)樣品位的加熱爐，對(duì)許多應(yīng)用都可以進(jìn)行無人干預(yù)操作。在Purge模式下，可以一次性上裝13個(gè)瓶進(jìn)入爐內(nèi)，進(jìn)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(shí)容納12個(gè)樣品瓶，以確保在上一個(gè)樣品被分析完之前，準(zhǔn)備好下一個(gè)樣品的分析。這一過程，大大節(jié)約了由于分析下一個(gè)樣品所需加熱恒溫平衡時(shí)間，也使樣品的重復(fù)性得到保證。提供樣品流路的同時(shí)，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(jìn)模式（Progressive Mode） 溫度漸進(jìn)模式以一個(gè)較短的時(shí)間基數(shù)，對(duì)同等量含同樣組份的一系列樣品恒溫平衡時(shí)間以等差級(jí)數(shù)遞增，得到一組色譜數(shù)據(jù)，同一組分，當(dāng)它在頂空達(dá)到平衡后，它的分壓是不隨時(shí)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(gè)的平衡時(shí)間。在這個(gè)模式運(yùn)行過程中，儀器將自動(dòng)選擇zui短的運(yùn)行時(shí)間，即能從單個(gè)樣品恒溫平衡到多個(gè)樣品恒溫平衡的自動(dòng)轉(zhuǎn)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(duì)于同一樣品瓶的多次頂空提取，得到多個(gè)樣品色譜圖，用于方法的開發(fā)和對(duì)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(biāo)準(zhǔn)的信號(hào)接口，外部準(zhǔn)備，啟動(dòng)、停止，準(zhǔn)備輸出， 運(yùn)行輸出等。 Provided ports to connect with any gas chromatograph with a standard interface.
