Macromolecules play an ever-increasing role in the products that we see, touch, and use in our daily lives. The research, development, and manufacturing behind these products requires detailed characterization of the composition, structure, size, and molecular weight of these macromolecules. At Houston MJ Associates, our mission is to provide hardware, expertise, and support to the polymer industry in the characterization process. The foundation of Houston MJ Associates' business is the DSV (Dilute Solution Viscometer) product line, which was purchased from Malvern in 2016. The years since 2016 have been exciting for our worldwide DSV customers as we have proven that Houston MJ Associates can provide top-notch sales, service, and support for the DSV technology now and well into the future. The recent addition of the Linkoptik line of particle size analyzers has significantly expanded the our portfolio. As a leading company in the field of particle size analysis by laser diffraction, Linkoptik has a growing number of patented technologies and extensive industry applications knowledge. This has allowed its customers to better understand a wide variety of materials ranging from pharmaceuticals to chemicals and polymers, as well as micro and nano particle suspensions, emulsions and sprays. The Linkoptik product line includes innovative, cutting-edge laser diffraction platforms, wet and dry sample dispersion units, spray particle size analyzers and powerful yet intuitive software. Technically advanced, reliable and robust, Linkoptik represents a tremendous value for customers looking to measure particle size and particle size distribution. Significant additional offerings from Houston MJ Associates include 1) a GPC/SEC and DSV sample analysis services, 2) aqueous, organic, and specialty GPC/SEC columns and 3) GPC/SEC bulk and specialty standards. It is our mission to become a one-stop GPC/SEC and DSV service provider for the polymer industry.
