1/16--1/8 钝化的不锈钢管硅烷化管子

为减少不锈钢管壁对气样中分析物的吸附性和降低对气样分解转化反应的催化活性，不锈钢管的内表面要经过特定的处理，使其具有高光洁度和惰性。

由于空气中低浓度污染物的监测需要，对采样定量管的内表面惰性要求大大提高，在内表面加上一层以硅元素为主体的非金属层，以隔绝气样与金属表面之间的直接接触。

应用：
1.采集和分析环境空气样中低浓度挥发性有机物（VOCs）。
2.污染源中的低浓度有毒有机物的采样和分析，不稳定或易被吸附的化合物（如含硫，含溴，含汞类化合物等）的采样和分析，通常也需要选用钝化的不锈钢管。

3.非甲烷总烃的测定

规格：1/8，  1/16
长度：1m，2m，3m，特殊要求请告知。

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
