使用401脫氧柱時(shí)，以下幾點(diǎn)需要特別注意：
?
老化處理：新柱或長(zhǎng)期未用的柱在使用前需進(jìn)行老化。先在常溫下通載氣約10分鐘排除柱內(nèi)空氣，再以程序升溫至最高使用溫度（280°C）老化1-2小時(shí)。老化時(shí)切勿連接檢測(cè)器，以免污染。
載氣要求：載氣中的微量氧也可能損壞固定相，因此建議使用高純載氣，并確保其中氧氣含量不超過(guò)1 ppm。必要時(shí)可為載氣加裝脫氧管。
安裝方向：安裝時(shí)注意色譜柱的進(jìn)口和出口方向（通常產(chǎn)品有標(biāo)識(shí)，如牌號(hào)面向操作者時(shí)左側(cè)為進(jìn)口）。
安全操作：拆卸色譜柱前，務(wù)必先將柱溫降至室溫，然后再關(guān)閉載氣。

選擇401脫氧柱時(shí)，需要考慮以下幾個(gè)因素：
儀器匹配：確認(rèn)脫氧柱的接口規(guī)格（如1/8英寸、1/4英寸）與你的氣相色譜儀（如安捷倫、島津、賽默飛等品牌多種型號(hào)均適用28）的進(jìn)樣口和檢測(cè)器接口是否匹配。
應(yīng)用需求：根據(jù)你的分析樣品（如工業(yè)氫、高純氧）和分析目的（脫氧或氧氬分離）選擇合適的柱長(zhǎng)、內(nèi)徑和填料粒度。
材質(zhì)選擇：常見(jiàn)為不銹鋼材質(zhì)，也可選擇玻璃柱管。
訂購(gòu)說(shuō)明：如需特殊的柱端堵頭（如不銹鋼過(guò)濾網(wǎng)）或采用

When using a 401 deoxygenation column, the following points need to be paid special attention to:
Aging treatment: New or unused columns need to be aged before use. First, let the air flow through the column at room temperature for about 10 minutes to remove the air inside. Then, use a programmed heating method to reach the maximum operating temperature (280 ° C) and age for 1-2 hours. Do not connect the detector during aging to avoid contamination.
Carrier gas requirements: Trace amounts of oxygen in the carrier gas may also damage the stationary phase, so it is recommended to use high-purity carrier gas and ensure that the oxygen content does not exceed 1 ppm. If necessary, a deoxygenation tube can be installed for the carrier gas.
Installation direction: Pay attention to the inlet and outlet directions of the chromatography column during installation (usually the product is labeled, such as the left side indicating the inlet when the brand is facing the operator).
Safe operation: Before disassembling the chromatography column, make sure to lower the column temperature to room temperature before turning off the carrier gas.
When choosing a 401 deoxygenation column, the following factors need to be considered:
Instrument matching: Confirm whether the interface specifications of the deoxygenation column (such as 1/8 inch, 1/4 inch) match the injection port and detector interface of your gas chromatograph (applicable to multiple models of brands such as Agilent, Shimadzu, Thermo Fisher, etc.).
Application requirements: Choose the appropriate column length, inner diameter, and packing particle size based on your analysis sample (such as industrial hydrogen, high-purity oxygen) and analysis purpose (deoxygenation or oxygen argon separation).
Material selection: Stainless steel is commonly used, but glass column tubes can also be chosen.
Ordering instructions: If you need special column end plugs (such as stainless steel filter screens) or
