Top 5 Things You May Not Know About LC Systems
1. The Russian botanist Mikhail Tsvet is considered to have ‘invented’ the chromatographic technique in 1903 when he reported separations of different plant pigments into a series of colored bands on a packed column. He called this technique ‘chromatography.’
2. In the 1940s, Martin and Synge developed the theory of partition chromatography and used mathematics to describe the separation process resulting from the use of a liquid-coated solid phase and a moving liquid phase.
3. The technique of paper chromatography was developed by Consden, Gordon and Martin in 1944. This technique was originally used for the identification of amino acids.
4. J.C. Moore of the Dow Chemical Company was the first to investigate the technique of gel permeation chromatography, doing so in 1964.
5. The first commercial HPLC was manufactured by Waters Corporation in 1969, and was known as the ALC100 HPLC. The company also unveiled a new category of LC technology known as Ultra Performance LC (UPLC) in 2004.
Top 6 Questions You Should Ask When Buying an LC System
1. How flexible is the system? Ask about whether the system can be optimized to meet your laboratory requirements.
2. What tubes, vessels, vials can it accommodate? Can components (such as additional detectors, valves, etc.) be upgraded in the future?
3. Is the software easy to use and operate? Can a demo version be put in place to get a feel for how the software functions for your laboratory’s workflow?
4. How is the system (not just its components) qualified during installation as to meeting manufacturer performance expectations?
5. Who provides the support and service for the product? Is it the manufacturer or a third party service group? If it is a third party service group, are they factory-trained?
6. Finally, ask about cost of the purchase, installation charges, and warranty extension costs.
