Jordi Labs specializes in the production of innovative polymeric media for Gel Permeation (GPC) and Gel Filtration (GFC) Chromatography. Our GPC and GFC columns represent over 35 years of continuous research and development efforts. Jordi resins are always crafted using high quality 100% divinylbenzene (DVB) or other crosslinkable packings. Jordi also operates one of the largest premier GPC service laboratories in the country. Our team’s recognized analytical expertise and dedication to customer satisfaction has significantly influenced the development of our revolutionary column media. Jordi’s unwavering commitment to quality and integrity is a promise that you are getting the finest GPC and GFC columns on the market today. We pride ourselves on delivering the best chromatography products and services, and offering expert support and advice to ensure your success.
Jordi Resolve GPC Columns: Jordi Labs has recently developed a novel packing material for GPC systems. This column packing is based on 100% divinylbenzene providing enhanced mechanical stability and utilizes a new synthetic process which results in a monodisperse polymer column packing. It is well known that broad particle size distributions in particle based columns produces variations in packing density, lowers column resolution, reduces the column permeability and generates high back pressure. New generation Jordi GPC columns prepared with monodisperse 100% divinylbenzene particles with precisely controlled particle diameter and finely controlled pore structure provide high efficiency, high separation capacity and low back pressure with greater bed stability. Scanning electron micrographs and particle size distribution of 5 μm macroporous column packing material with 10³ A pore sizes are shown in Figure 1. The uniform size distribution and perfect spherical shapes are clearly seen.
Mixed bed Resolve columns allow for separation over the molecular weight range from 200 to 3,000,000 g/mol (PS equivalent) with a coefficient of determination (R²) of 0.999. For higher molecular weights, Jordi Labs offers its Jordi Resolve DVB 13 μm columns. New generation Jordi Resolve columns (7.8 mm x 300 mm) are produced to allow separation over the molecular weight range from 500 to 12,000,000 g/mol (PS equivalent).
Aqueous applications present a significant challenge in the field of size-based separations, due to the difficulty in preventing sample-column interactions. Jordi offers three column chemistries for GFC in aqueous mobile phases including: Jordi Resolve xStream, Jordi Resolve Anion and Jordi Resolve Cation.
