How to collect C4 raw materials
Thread Content
Our company produces isooctane, with the main raw material being C4 after etherification. Typically, samples of this raw material are collected using tin foil bags for analysis; we are wondering if there are other methods that allow for faster sample collection and better analysis results. I wonder how other units collect it. Thank you for the guidance.

A liquefied gas sampler is a stainless steel cylinder with valves at both ends; it allows sampling under pressure, and it enables the immediate discharge and cleaning of the sampled material, eliminating any risk of fractionation during sampling. It offers good representativeness and a large sample size; depending on the analysis requirements, either liquid-phase or gas-phase composition analysis can be carried out. As shown in the following images: http://img008.hc360.cn/y3/M04/44/53/wKhQh1UG4_uESiuxAAAAAH5WgEU484.jpg http://file3.hi1718.com/productsimage/2015/05/15/20150515115339116.jpg
It is usually called: sampling cylinder. Additionally, the sampler modified from a six-way valve is also very useful, as it allows for direct quantitative sampling using a measuring tube.
