Our extensive family of products offers a variety of particle sizes and column designs to meet all separation needs, including improved resolution, enhanced sensitivity, faster analysis and consistent performance. Contact us. Popular HPLC and UHPLC columns Normal-Phase HPLC The column is filled with tiny silica particles, and a non-polar solvent, for example, hexane. A typical column has an internal diameter of 4.6 mm or smaller and a length of 150 to 250 mm. Non-polar compounds in the mixture will pass more quickly through the column, as polar compounds will stick longer to the polar silica than non-polar compounds will. Reversed-Phase HPLC The HPLC is essentially an adaptation of column chromatography - so it might be a good idea to have a (very quick) look at that as well.

High performance liquid chromatography is basically a highly improved form of column chromatography. Instead of a solvent being allowed to drip through a column HPLC systems currently use variable loop, fixed loop, and syringe-type injectors. These are activated manually, pneumatically, or electrically. Mechanical problems involving the injector (e.g., leaks, plugged capillary tubing, worn seals) are easy to spot and correct. Use a precolumn filter to prevent plugging of the column frit due to physical degradation of the injector seal.

In all cases, don't forget to put aside plenty of funds for all of the normal consumables (e.g. many HPLC columns, HPLC solvents, High Resistance Water system, Tubing, maintenance parts) and Feb 01, 2016 · Chromatographers around the world are using HPLC techniques to ensure the safety of our food and water, develop life-saving pharmaceutical products, protect our environment, guard public health, and that’s just the start of it. The more you know about chromatography, the more you can get done with this amazing technology. Step #1: Select a Column to Compare : Select a column to compare from the list below. A similarity factor, F s, will be calculated for each of the other columns in the database (below).

We would like to show you a description here but the site won’t allow us. HPLC, column section measurements are 2.1 mm to 4.6 mm distance across, and 30 mm to 250 mm length. Additionally, HPLC segments are made with smaller sorbent particles (2 μm to 50 μm in normal molecule size). This gives HPLC high determining or resolving power (the capacity to recognize components) while isolating mixtures, Tips for better search results. Ensure correct spelling and spacing - Examples: "paper jam" Use product model name: - Examples: laserjet pro p1102, DeskJet 2130 For HP products a product number. How does one get HPLC experience? I've worked with it a bit in the academic world for doing protein purification and with MS for verifying product in organic synthesis. However, so many jobs i see now want a year or more of HPLC experience in industry, and it's infuriating. High-performance liquid chromatography (HPLC) was born half a century ago, and has since become one of the most widely used analytical techniques in the world. The demand for higher separation efficiency, faster analyses and greater throughput has been the driving force for extraordinary advances in stationary phases. As a life science researcher, you need the tools and support to help you create the scientific foundation in pursuit of expanding the knowledge-base, whether it is understanding fundamental biology, finding new biomarkers, discovering ways to improve our quality of life, or other areas of research.
