型号：20%PEG-20M/GCS880 AW DMCS（80-100目）
应用： HJ/T 35-1999 固定污染源排气中乙醛的测定 气相色谱法
乙醛是一种低沸点（１９℃）、易挥发的液体。高纯度的乙醛在保存、分析含量方面有较大的难度，而乙醛水溶液分析测定是比较容易的。现有的测定方法分为间接法（如气相色谱法）和直接法，后者取样方法复杂，操作。
浩瀚色谱（山东）应用技术开发有限公司分析测定大气中乙醛的气相色谱分析方法。用１ｍｌ注射器将采集的气样直接进入聚乙二醇（ＰＥＧ）－20０００色谱柱，用ＦＩＤ－ＧＯ法，能很容易测出大气中的乙醛，zui小检出浓度可达０．４ｍｇ／ｍ３，方法简单可靠，适合常规监测。

Direct Injection Gas Chromatographic Analysis of Acetaldehyde in Air 20%PEG-20M/GCS880 AW DMCS Packed Column
Direct Injection Gas Chromatographic Analysis of Acetaldehyde in Air 20%PEG-20M/GCS880 AW DMCS Packed Column Details:
Name: Packed Column
Specifications: 2m*3mm (inner diameter)
Model: 20%PEG-20M/GCS880 AW DMCS (80-100 mesh)
Application: HJ/T 35-1999 Determination of Acetaldehyde in Exhaust Gas from Stationary Pollution Source Gas Chromatography
Acetaldehyde is a low boiling point (19°C), volatile liquid. High-purity acetaldehyde is difficult to store and analyze, while the analysis and determination of acetaldehyde aqueous solution is relatively easy. Existing determination methods are divided into indirect methods (such as gas chromatography) and direct methods. The latter has a complicated sampling method and operation.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. is a gas chromatography method for the analysis and determination of acetaldehyde in the atmosphere. Use a 1ml syringe to directly enter the collected gas sample into a polyethylene glycol (PEG)-20000 chromatographic column. Using the FID-GO method, acetaldehyde in the atmosphere can be easily detected, and the minimum detection concentration can reach 0.4mg/ m3, the method is simple and reliable, suitable for routine monitoring.
