Let’s Dive into Kimble/Kontes KIMAX Chromatographic Columns, Kimble Chase 17800-19300
The Kimble/Kontes KIMAX Chromatographic Columns, Kimble Chase 17800-19300 are a cornerstone of analytical chemistry, offering a reliable and chemically inert platform for separating and purifying compounds. Manufactured by Kimble Chase, these columns promise exceptional peak profiles thanks to their unique design that avoids free alumina. With a calibrated opening for precise retention time control and the ability to create a vacuum cavity for easy packing removal, this column stands out in a field crowded with alternatives.
My journey to these columns began with a persistent challenge in my work as an outdoor and tactical gear specialist. Specifically, I needed to analyze the chemical composition of various coatings and materials used in gear manufacturing to ensure compliance with environmental regulations and quality standards. This required highly reliable chromatographic separation.
Upon unboxing, the first thing I noticed was the robust feel of the borosilicate glass. It felt significantly sturdier than some of the cheaper plastic columns I’d worked with before. The precision of the dimensions (19mm I.D. x 300mm Length) was immediately apparent, hinting at the level of control this column would provide.
I had been using standard glass columns with fritted discs, and while they were adequate, I often struggled with inconsistent flow rates and peak tailing due to the alumina content. I also considered pre-packed columns from a competitor, but the cost was prohibitive for the number of samples I needed to process. The Kimble/Kontes KIMAX Chromatographic Columns, Kimble Chase 17800-19300 struck me as the perfect balance of quality, control, and cost-effectiveness.
My initial impression was one of cautious optimism. The promise of smoother peaks and the controlled retention time were certainly appealing, but I was eager to see how it would perform in the real world, separating complex mixtures of chemicals extracted from durable outdoor fabrics.
Real-World Testing: Putting Kimble/Kontes KIMAX Chromatographic Columns, Kimble Chase 17800-19300 to the Test
First Use Experience
My initial testing ground was the lab where I analyze fabric samples for chemical composition, focusing on things like flame retardants and waterproofing agents. I used the column to separate a complex mixture of hydrocarbons extracted from a newly developed tent fabric, using hexane as the mobile phase. The aim was to isolate and quantify the individual components for quality assurance.
The column performed exceptionally well under these conditions, providing a clear separation of the target compounds with minimal peak tailing. The controlled backbushing allowed me to fine-tune the retention time, ensuring optimal resolution between adjacent peaks. The ease of creating a vacuum cavity for packing removal also simplified the cleaning and preparation process, saving valuable time.
There were no major issues during the first use, although I did find that optimizing the packing density required some experimentation to achieve the desired flow rate and separation efficiency. This was easily overcome with a few trial runs and adjustments to the packing procedure.
Extended Use & Reliability
After several weeks of consistent use, the Kimble/Kontes KIMAX Chromatographic Columns, Kimble Chase 17800-19300 have proven to be a reliable workhorse in my lab. I’ve used them for analyzing a wide range of samples, from fabric coatings to polymer blends, and they have consistently delivered accurate and reproducible results. The column shows minimal signs of wear and tear, even after repeated use with various solvents.
Maintaining the column is straightforward; simply flushing it with an appropriate solvent after each use effectively removes any residual compounds. Occasional repacking is necessary, but the ease of vacuum cavity formation makes this process quick and efficient. Compared to my previous experiences with fritted glass columns, the Kimble/Kontes KIMAX Chromatographic Columns, Kimble Chase 17800-19300 offer superior performance, particularly in terms of peak shape and resolution.
