鈍化的不銹鋼管硅烷化管子 詳細信息：

為減少不銹鋼管壁對氣樣中分析物的吸附性和降低對氣樣分解轉化反應的催化活性，不銹鋼管的內表面要經過特定的處理，使其具有高光潔度和惰性。

由于空氣中低濃度污染物的監測需要，對采樣定量管的內表面惰性要求大大提高，在內表面加上一層以硅元素為主體的非金屬層，以隔絕氣樣與金屬表面之間的直接接觸。

應用：
1.采集和分析環境空氣樣中低濃度揮發性有機物（VOCs）。
2.污染源中的低濃度有毒有機物的采樣和分析，不穩定或易被吸附的化合物（如含硫，含溴，含汞類化合物等）的采樣和分析，通常也需要選用鈍化的不銹鋼管。

3.非甲烷總烴的測定

規格：1/8，  1/16
長度：1m，2m，3m，特殊要求請告知。

Passivated stainless steel pipe silanized pipe
Passivated stainless steel pipe silanized pipe Details:

In order to reduce the adsorption of the analyte in the gas sample by the stainless steel tube wall and the catalytic activity for the decomposition and conversion reaction of the gas sample, the inner surface of the stainless steel tube must be specially treated to make it have a high smoothness and inertness.

Due to the monitoring needs of low-concentration pollutants in the air, the requirements for the inertness of the inner surface of the sampling loop are greatly increased. A non-metallic layer mainly composed of silicon is added to the inner surface to isolate the gas sample from the metal surface. direct contact.

application:
1. Collect and analyze low-concentration volatile organic compounds (VOCs) in ambient air samples.
2. Sampling and analysis of low-concentration toxic organics in pollution sources, sampling and analysis of unstable or easily adsorbed compounds (such as sulfur, bromine, mercury-containing compounds, etc.) usually require passivated stainless steel tubes .

3. Determination of non-methane total hydrocarbons

Specification: 1/8, 1/16
Length: 1m, 2m, 3m, please inform us of special requirements.
