why choose us

When it comes to GC capillary columns and consumables, we know you have many suppliers in the chromatography marketplace to choose from. Over the years those numbers have actually dwindled as the industry has experienced several mergers and acquisitions and even division shut-downs where some popular brands simply have disappeared. From large multi-national corporations and conglomerates with huge R&D and marketing budgets to smaller companies such as Quadrex, you can get what you need for your critical GC applications. So, why choose us?


Our expertise dates back beyond the time of our founding in 1976. Quadrex’s founder, Dr. S.R. Lipsky, had been investigating gas chromatography instrumentation and column technologies since the early 1960s. After the 1960 Golay patent (U.S. Patent #2920478, assigned to Perkin Elmer) on capillary columns expired in 1975, the market finally opened to commercially available GC capillary columns. Since 1976, Quadrex has honed and applied its 40+ years of technical expertise to its manufacturing processes and has produced thousands of capillary columns for chromatographers around the world.


Our quality extends from our experience. We take pride in our manufacturing technology and the ability to offer a quality product. Quality control takes place at every stage of production and every column goes through extensive testing prior to leaving our door. The GC column market is highly competitive, our longevity in this market is a testament to the quality we put into each of our columns.


Quadrex is still privately owned and is now under second generation management. We care about our product quality and pride ourselves on personalized customer service. Every customer is important to us and we treat you as if you are our only customer. Think of it as the service you’d receive walking into your local hardware store compared to a big box store or sitting in your local pub “where everyone knows your name” instead of a big chain restaurant.

When recently accepting some custom work, we received this compliment, “My colleagues have been given the run around by unhelpful and sometimes arrogant column companies. Your response is so incredibly refreshing and we will definitely be doing business with you….”


The fused silica tubing that is used to manufacture today’s state-of-the-art GC columns comes in a variety of industry-standard internal diameters. All column manufacturers offer a multitude of standard column configurations to meet many common GC applications. In addition, we will produce columns in any length and any film thickness (within the given limits of the particular stationary phase). We can offer custom support cages and even put our columns onto a competitor’s support cage if you prefer it. Contact us with your analytical requirements; if we don’t have an off-the-shelf column for your application, we will work with you to develop a custom solution.

Our Commitment to You

Quadrex is committed to manufacturing the highest quality capillary columns at competitive prices. We will work with you to determine the best column solution for your application. We look forward to having you as our customer.
