I started a new thread about a benzene testing kit we developed to allow end-users and wholesalers to pull sample(s) of liquid phase hydrocarbons and have the sample(s) analyzed for purity and benzene analysis specifically for presence of benzene. $200 for the kit and our in-house analysis. We cover all shipping costs, even if you want to have the sample sent to some other lab for analysis.
An investment of a couple hundred dollars allows both resellers and end-users to confirm the accuracy of the analyses provided by their supplier(s). The benzene issue has impacted both resellers and end-users with some end-users reporting losses of tens or even hundreds of thousands of dollars by having their extractant test positive for benzene.
As an industry, we need to identify the source(s) of the butane that is contaminated with benzene. Message me here or email the address in our original post for more information. Jim
