毛細(xì)管柱測(cè)定依地酸二鈉中甲醛殘留量 詳細(xì)信息：
浩瀚色譜（山東）應(yīng)用技術(shù)開(kāi)發(fā)有限公司建立依地酸二鈉(EDTA-2Na)中殘留甲醛的測(cè)定方法。方法:采用頂空氣相色譜法測(cè)定。HH-WAX氣相毛細(xì)管柱(30 m×0.25 mm,0.25μm),分流進(jìn)樣,分流比為2∶1;載氣為N_2,流速為1.0 ml·min~(-1);檢測(cè)器為FID;進(jìn)樣口溫度為230℃,檢測(cè)器溫度為260℃;采用程序升溫法:起始溫度40℃,保持6 min,再以40℃·min~(-1)速率升溫到230℃后,維持10min;進(jìn)樣量為1μl。分別取對(duì)照品溶液和供試品溶液,95℃加熱平衡25 min,頂空進(jìn)樣,按外標(biāo)法以峰面積計(jì)算含量。結(jié)果:甲醛標(biāo)準(zhǔn)溶液在5.10~102.00μg·ml~(-1)濃度范圍內(nèi)與峰面積的線(xiàn)性關(guān)系良好(r=0.999 7),平均回收率為84.60%(RSD=3.82%,n=9)。結(jié)論:本方法簡(jiǎn)單、快速、準(zhǔn)確,可以用于依地酸二鈉中甲醛殘留量的測(cè)定。

Determination of Residual Formaldehyde in Disodium Edetate by Capillary Column
Determination of formaldehyde residues in disodium edetate by capillary column Details:
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a method for the determination of residual formaldehyde in disodium edetate (EDTA-2Na). Methods: Determined by headspace gas chromatography. HH-WAX gas-phase capillary column (30 m×0.25 mm, 0.25 μm), split injection, split ratio of 2:1; carrier gas was N_2, flow rate was 1.0 ml·min~(-1); detector was FID; The temperature of the injection port was 230 °C, and the temperature of the detector was 260 °C; the temperature program was adopted: the initial temperature was 40 °C, maintained for 6 min, and then heated to 230 °C at a rate of 40 °C min~(-1), and maintained for 10 min ; The injection volume is 1 μl. Take the reference solution and the test solution respectively, heat and equilibrate at 95 ℃ for 25 min, inject the sample into the headspace, and calculate the co
