Troubleshooting HPLC Injectors (Manual and Automated) Sample injectors are a critical component of a chromatography system. Understanding how they operate as well as the proper techniques to use and maintain them are fundamental skills needed to operated an HPLC system. Lets briefly discuss some of these fundamentals as applied to a standard manually operated HPLC injection valve and also in an automated mode as found in an autosampler. Maintain continuous HPCL flow between the load and inject positions and protect against pressure shock by using Thermo Scientific™ Rheodyne™ and i Sample Injectors. The Make-Before-Break (MBB) design ensures uninterrupted flow during sample injection. These stainless-steel, dual-mode injectors can use partial filling for zero sample waste or complete filling for better reproducibility. The simplest way to inject your sample into the system. Use a manual injection valve and choose from a large range of different sample loops, available for different applications. For analytical HPLC, our valves feature a wide back pressure range of up to bar with a mm bore size. All valves can be equipped with an automatic valve drive.
